u/NoradIV · 16 pointsr/askcarguys

Yep. These devices are made for that application.

If you store your car outdoor, I'd recommend getting a car cover similar to this (get one that fit your car), which will reduce paint damage from UV exposure. I also put the car on a tarp to reduce rust under it (I live in Canada, this is good for winter especially).

If you live in an area where it can go below freezing, leave your fuel tank completely full.

Fuel stabilizer is a good idea, but not necessary for 5 months.

If you want, you can also over inflate your tires to prevent them from flat spotting. Again, this is not necessary, more like the cherry on top.

​

So, to summarize, get a battery maintainer and a tarp if outdoor. Change the oil when you come back. If you stay for like 6 months, then leave the oil in the car when you leave and change when you are about to drive it.

If the battery is getting weak (especially in these colder temps), check the charging level of the alternator. If it's ok, pick up a battery charger that will automatically switch to float once reaching full charge. Throw the battery on there overnight.

Keep cold out of your gear. Like in hiking, being cold is worse than wet since it'll sap your energy. I wear a balaclava around my head and just picked up a fleece neck warmer to keep cold wind from entering my coat and helmet.

Pinlock visors are great at keeping your visor from fogging up if you wear a full face helmet.

Reflective tape on your helmet, bike and gear will add to your visibility.

Keep track of your tires and brakes. Give yourself 20 minutes to gear up and check the bike before you leave. You don't want to forget a piece of gear because you were in a rush.

Don't override your ability in lousy weather and know alternate, safer and slower routes if you need to get off the highway. It happened to me once in Skagit Valley when a rainstorm pushed me three lanes over (I shouldn't have been going so fast in the left lane) so I exited and took a really slow trip on some farming roads, then the old 99 highway all the way to Seattle.

Be aware and cautious, especially in the dark and wet around the unmindful cagers in this town, but have fun! These cold, sunny, dry days have been a blast to ride.

u/ACDRetirementHome · 9 pointsr/lowcar

If there's a plug nearby, you might want to pick up a battery tender. This should monitor and keep a "float" charge on the battery.

Example: http://www.amazon.com/Deltran-Battery-Tender-021-0128-Charger/dp/B00068XCQU

There's a cheaper Jr version that might be more appropriate for you.

Also, your battery may need replacement anyway since deep discharges damage the battery chemistry.

u/Bing803 · 9 pointsr/bonnaroo

This is what we used this last year Stanley J7CS 350 Amp Battery Jump Starter with Compressor https://www.amazon.com/dp/B00RZXVQSU/ref=cm_sw_r_cp_api_0dYryb53RQN05

Jump starts your car and comes with an air compressor. My group of four was able to charge our phones and play music all weekend. Just get a power inverter ( BESTEK 200W Power Inverter DC 12V to 110V AC Inverter with 4.2A 4-Port USB Car Adapter https://www.amazon.com/dp/B00EY6RJKA/ref=cm_sw_r_cp_api_8kYryb7XBT29W ) and you can power anything with it.

u/WannabeNomadic1 · 8 pointsr/vandwellers

> the frankenfridge

I like the term frankenfridge! I just got my freezer all hooked up a few days ago. Something that I didn't realize at first was that some inverters aren't easy to set up with the relay. I originally got this Krieger one but it doesn't automatically turn back on when the relay gives it power (so the relay would turn off the inverter/cut its' power when it got below 38°, but when it went back above 38° the relay would switch but the inverter wouldn't turn on unless the power button was physically hit). Ended up returning that one and getting this simple Madpower one that just has a physical on/off rocker switch (no other buttons or remote switches) and it works flawlessly. Just something to keep in mind, wish I had realized before I started!

u/Cool_Bastard · 8 pointsr/preppers

Here's what I got, though I was going to consolidate it in another post this week.

So I posted this on Reddit last month after I finally got around to getting the gear we needed. There are many non-emergency items that go in the emergency kit. This guy's post really made an impact on my way of thinking. I see the car kit as not exclusively for EMERGENCIES but for all situations where you need something that you would normally have at home and you simply just don't have it, like a pair of socks or knife and fork. There are two parts to the car kit, the Emergency Car Kit (which goes in a pack in the back of the car) and the Supplemental Car Kit which goes in between the front seats which is for a specific emergency where there's an accident and you need to get out and help someone asap. Some of the stuff is duplicated, because I like redundancy and they're needed in both scenarios: asap (supplemental) and general purpose (main car kit).

Supplemental Car Kit:

  • Road flares (electric and olden fire type kind)
  • Small first aid kit
  • High visibility reflector vest - for when you need to cross the highway and not get hit by other cars, especially at night.
  • Car Jumper - This needs to be charged and ready to go.
  • Hand crank flashlight - Not very bright, but it's for dire emergency where you don't need to worry about batteries.
  • Inverter for AC power - I just happen to have one of these that I got a while back. I think it's more of a luxury item but can still be handy in a pinch. You can charge a laptop on it along with phones or whatever.
  • Garbage bag - Not for emergencies, but for picking up garbage when you're in a place that has trash all over and humans suck. This makes picking up garbage easy, so there's no excuses.
  • Gloves - For picking up garbage, doing car work, getting in fight (I'm serious) and pulling someone out of a broken window.
  • Parachute cord - An impulse item. I always need the stuff when I don't have it.
  • Knife - You can never have too many knives
  • Tire pressure gauge

    Here are the additions to the Emergency Car Kit:

    Emergency Car Kit:

  • Small back pack - My thinking is that this is better than a big plastic tub. In the event of a true emergency it's ideal to be able to grab & go, which you can't do with a tub.
  • Windproof matches - Because.
  • Knife & Fork Kit - You need utensils (for each person) in the event that you need to eat. There are many non-emergency items that go in the emergency kit.
  • Steel tweezers - because the plastic ones in first aid kits suck ass.
  • Extra AA & AAA batteries
  • 2 Garbage bags
u/Kristeninmyskin · 7 pointsr/EatCheapAndHealthy

How about selecting what he will eat off of the healthy list and have a contingency plan for hot food? I think I can help you out here. There are several devices to heat food even on the go. The Mini Crockpot Lunch Warmer is about $15-$20 (depending on color choice) and is great for soups, stews, (turkey?) chili, and pasta with sauce. There is also the Hot Logic Mini Oven ($30-$40 watch for sales!), which is a hot plate inside an insulated, zippered bag. You can put a frozen dinner still in the box, cooked leftovers or raw chicken or fish and it cooks/reheats slowly at a low heat. Plug either of them into the car's lighter with an AC Car Converter ($17) in the morning/beginning of his work day and it will slowly come to temperature and hold it until he's ready to eat!
They took away our microwave at work and I've had to adapt. I love them both!

u/rbandit · 7 pointsr/vandwellers

I didn't have the space, money or time to put in a deep cycle house battery and all the wiring that goes along with it, so I bought two of the phone bank batteries you linked to.

All of my lighting runs off of 5v USB outlets (as well as my phone and tablet,) and I can last a week without recharging the power banks.

I also have a simple cigarette lighter inverter like this one so I can run the occasional 120v tool.

This set up lets me charge my batteries while I'm driving, in a coffee shop or at work, or from a portable 20w solar panel if I'm boondocking.

u/alshayed · 6 pointsr/SleepApnea

Personally for local or camping (not air travel) I like the 35-55 AH AGM SLA scooter batteries. (SLA = sealed lead acid aka non-spillable) If you turn of heated hose & humidification (passover humidification is okay) they will last a few nights. See the ResMed battery guide for more detailed run estimates at https://www.resmed.com/us/dam/documents/articles/198103_battery-guide_glo_eng.pdf.

Basic list of parts you need:

u/joshu · 6 pointsr/CNC

you want a buck converter. there are plenty of adjustable ones. eg http://www.amazon.com/dp/B019RKVMKU

u/uzikaduzi · 5 pointsr/askscience

you got some good replies... just want to be a little more specific. something like a battery tender is good to leave connected. it will cycle on and off to keep the battery charged... Trickle chargers are manual and push a constant amount of amps until you turn them off.

the manual type are still not obsolite... for one you can charge a battery quicker because you can choose the amperage to charge at. Another benefit is if you have a very discharged battery, the newer battery tender types will not charge it because it's measuring too low of voltage and is programed to assume it's damaged... the manual type, sometimes you can set it very low and charge it up enough to switch to back to the battery tender type.

u/SuperConfused · 5 pointsr/BMW

I have a different idea for you. A guy I work with has a 2007 that had the same issue, but he simply did not have the money for a new one. He was stranded at work, again, when we were talking about it. His battery was in terrible shape; he put it on the charger every night to be able to get to work.
I thought about getting him an extension cord, but he was 200' from the closest outlet, so I told him that if he tried one of these solar trickle chargers, I would buy it from him if it did not work. He has managed to get to and from work for over a month in this North Dakota weather with no issues. I just plugs it in when he parks.

u/Nomorekidzplz · 5 pointsr/beyondthebump

Some cars have an outlet (like you just plug anything in that can go into a house outlet), but usually you can get an adapter that plugs into the cigarette lighter/battery port and then your pump can plug into that. I believe this one is the one I used.

Disclaimer: I'm American and this worked with my car. I don't know if it's different in other countries/car makes.

u/dhanson865 · 5 pointsr/leaf

It's an ideal use of a Leaf. Your only issue is the little 12v battery won't get charged in short trips.

Either use the windshield wipers on every trip (the leaf charges the 12v faster when the wipers are on and for 2 mins afterwards) or buy an external charger like https://smile.amazon.com/dp/B004LWVEKS and charge the 12v every month or two.

Really you can drive it and not worry but if you want to be preventative so you don't have to deal with a dead 12v someday by surprise you can do so.

Note this isn't true just for the Leaf, it'd be the same for any car you drive on that short of a trip.

u/rainwhite · 5 pointsr/vandwellers
  • The couch pulls out and lifts up like this.

  • It's about 60 inches square. I'm 5'11" and can sleep fully extended on it if I sleep diagonally. I also have a foam pad that I can put on top of the safe for additional leg room. I usually sleep in a hammock though.

  • I can stand up fully. There's about 6'4" of head room in the center of the van. My friend is 6'3" and finds it to be a bit cramped.

  • Electricity is provided by four 100W solar panels on the roof and three 100Ah batteries up front. This powers a fridge, a vent, lights, and outlets. I have 12V car outlets and USB outlets. For odd proprietary plug A/C-only devices I have a little inverter.

  • I have a little fridge. I left space for a propane tank in the big cabinet and will probably get a little propane burner at some point.
u/motoman701 · 5 pointsr/PS4

I've successfully powered a PS4 and computer monitor in my car, works very well. The tech specs for the PS4 say 165 watt maximum. Any monitor or TV you use should have it's specifications listed as well. Here's an example of a pretty inexpensive one, it says 24 watts. Then just buy an inverter that exceeds the total of the PS4/Monitor/anything else you'll be using at the same time. Here's a reasonably inexpensive inverter that says it'll provide up to 150W if you're powering it using the cigarette lighter, otherwise you have to hardwire it to your cars battery (that's what I had done, the hardwire route) and it'll provide up to 500W which should be plenty

u/HaiImBRIAN · 5 pointsr/prius

I use my car as a generator when camping and it is awesome. I usually use it to run a few lights, charge electronic devices, and speakers. It burns very little fuel and probably burns at a rate of 1/10 a gallon per hour.

I've been using this inverter and I really like it because it displays the output. It helps me ensure I'm not overloading my car. With all my devices, I'm using only a max of 30 watts. Although it's rated for 500w, I heard you arn't suppose to run it that high without it directly connecting to the 12v Battery.

u/bedpimp · 5 pointsr/vandwellers

Congratulations on your first night out!

What about a battery jump pack? Some come with inverters built in. You could charge it while you're driving, and unplug it when you're using it.

https://www.amazon.com/Stanley-PPRH7DS-Professional-Inverter-Compressor/dp/B01DLYQ4DS/ref=sr_1_5?ie=UTF8&qid=1486318416&sr=8-5&keywords=jumper+inverter

As mentioned above, knowing what you need the electricity for makes it easier to determine a solution.

u/Rubcionnnnn · 5 pointsr/motocamping

Heres a couple things I like having on my bike when I travel:

AC inverter: gives you a 110v outlet in case you need to power something like a phone charger and you don't have a 12v usb connector.

Water purifying tablet: They take up about a cubic inch of space and may save your life.

Large wet wipes: For giving yourself an on the go shower in case you meet your future wife and there is no shower access.

Small mess kit: I have a serbian mess kit and I love it. The knife included has a can opener and a bottle opener and is serrated and well made.

Head lamp: Because holding a flashlight while its cold and you are trying to do something sucks. I prefer ones that have single large diodes instead of lots of little ones as they are brighter and have better color. Also I try and get ones that use 18650 batteries so I can share a charger and batteries.

u/2comment · 5 pointsr/PlantBasedDiet

I used to puncture (not open) cans of veggies, like corn, drain 1/3 the liquid, and heat them in the engine compartment of my car while driving. Think I moved beyond that.

Hard pretzels are consistently the one snack that's with low/no oil. Still would check ingredients. Not quite WFPB, but widespread, vegan and low fat. Still, I find snacks like these don't give good satiety and I keep reaching for them. Easy energy.

Taco Bell is vegan with modifications. Enough oil in it though but food on the go. The two easiest and cheapest things to order is thus:

  • Bean Burrito. Make it fresco (means replace dairy/cheese with pico de gallo).

  • Crunchy or Soft Taco. Make it fresco. Remove Beef. Add black beans.

    Grande meals composed of this are huge and cheap. Check your orders before leaving. Some locations really are bad at screwing it up.

    Some equipment I recommend in your situation:

  • A good chef's knife for chopping and prep work and a short knife (2-3") for peeling and other work.

  • a foldable mat to do chopping on. These are cheap and much easier to clean and portable than wooden blocks.

  • A collapsible silicon colander. Portable. To clean greens. I don't use a salad spinner much anymore, takes up a lot of room and I don't want my greens that dry.

  • Like before, a collapsible silicon bowl for salads and other prep plus to microwave and eat direct from. Easier than constantly tossing paper plates.

  • small glass jar (from marmalade or anything used) to mix dressing with.

    For much of your cooking, a microwave will actually be enough. Oatmeal, potatoes, rice, beans. Sure spaghetti and the rest will work too with practice.

    Panfrying and searing isn't a major requirement in the WFPB kitchen and much could also be done in a conventional oven. You can get a toaster-oven for around $50 if you stay in the same room consistently although I don't think it's necessary. You can get yourself an countertop cooktop for $50-100, but the room will unlikely have ventilation or an outdoor, so this or toasteroven can backfire if smoke occurs.

    There is one product I don't necessarily recommend for the hotel with the microwave, but if you are out on the road with a car a lot, and that's a HotLogic Mini Oven:

  • https://www.amazon.com/HotLogic-Mini-Personal-Portable-Black/dp/B00EC7XJ00/ref=sr_1_3?ie=UTF8&qid=1550340406&sr=8-3&keywords=portable+oven

  • https://www.amazon.com/Foval-Power-Inverter-Converter-Charger/dp/B01H2XD2DY/ref=sr_1_6?s=automotive&ie=UTF8&qid=1550340598&sr=1-6&keywords=car+inverter

    Consider this not for cooking but for reheating. It's a glorified hot plate that won't burn anything. I recommend the 12v with an good inverter in the car over a 12v version for the simple reason that you can use it in hotel rooms without modification. If you buy a 12v version and buy an adapter for outlets, you are much more likely to forget the adapter in hotel rooms.

    If it's in the running due to extra people, 2 mini size is better than one family size imo.

    The pyrex 6 cup they sometimes bundle with it is not spillproof so it was useless for soups and other wet stuff, but I got a 46 or 54oz glass glasslock-style spill-proof container at a local Marshalls that was perfect.

    There is also those Indian Heat n Eat meals. Kohinoor and the like. Many have butter but there were some vegan varieties.

    Also, up raw food eating. Fruits, salads, etc.
u/[deleted] · 4 pointsr/collapse

Multipurpose waterproof match case. I prefer this case because it's not much bigger than other waterproof cases, but has other stuff built into it. I put waterproof matches in it along with the striker strip from the package. The whistle is good for signaling. The other functions are marginal, so I supplement them with the actual things, which consist of a signal mirror, lensatic compass, and emergency fire starter.

A stove and solid fuel. I was pretty impressed with this particular one when I received it. It's stainless steel, well constructed, and you can store four fuel tabs inside of it.

A multitool and a fixed-blade knife. I don't have either of these specific models, but they seem pretty decent.

A folding shovel. These are good for burying waste, helping a car gain traction in the winter, etc.

A self-adhesive bandage. This is a three-pack. The single one cost $4 locally. Buy this one and leave the other two in your medicine cabinet. Wrap the remaining one around a piece of cardboard and put it in your emergency pack.

Disposable antibacterial wipes.

Antimicrobial silver gel. Like Neosporin, but better. Stays on a wound for multiple days without covering, and the colloidal silver is a strong antimicrobial agent. See the oligodynamic effect.

Dust masks. This is for a 50-pack, but for half the price, you only get 10 at a local store. These help prevent you from spreading germs if you're sick, and keep you from inhaling macroscopic particles if you're in a dusty/dirty area.

QuikClot sponge bandage. This helps to stop bleeding from major injuries. Along with an Israeli battle dressing you have two great ways to help stem major bleeding, separately or combined.

Local anesthetic for stings. Good for numbing injuries other than stings, too.

Sterile pads, 4” x 4”.

Sunscreen.

Cigarette-adapter power inverter. Good for charging small electronics.

Hand warmers.

Work gloves and watchcap.

All of the following are probably best bought in stores or scrounged up around the house:

Toothbrush, toothpaste, floss, all with obvious uses.

Aspirin, for heart attacks and pain, ibuprofen for pain, anti-histamine for allergic reactions, and Imodium or off-brand equivalent for diarrhea. I can't stress having Imodium enough. Having cramps and shits can render you unable to do anything for long periods of time, even more so than other ailments.

A disposable razor can be used to shave to keep up appearances, or to shave the area around a wound for better bandaging.

Maxi pads and tampons can be used as intended as well as to prevent bleeding from wounds.

Toilet paper. Wrap it around a piece of cardboard to save space.

Bandanas or an old shirt can be used to make a sling, protect yourself from the sun, filter macroscopic particles out of water, filter dirty/dusty air, etc.

Hot chocolate with caffeine added can be used to help stay alert.

Lighters are a must-have to start a fire.

I also have a Ziploc bag containing about ten cotton balls soaked in petroleum jelly. They're great firestarters.

Cash. Keep various bills and coins in an amount that you think is suitable for emergencies.

Maps. Carry folding maps of your area, state, and surrounding states.

I think that covers everything that I have. There's a lot of redundancy, but it all fits in my bag, so I'm happy with it. I'm definitely interested in hearing thoughts as to what can be added or changed.

u/t0ny7 · 4 pointsr/photography

What you should do is buy a sealed lead acid battery, a power inverter, 12v clips to cig lighter and a charger.

I just picked those products as examples but that would work and would cost around $50. It could probably be cheaper if you look around.

Also the batteries in most small UPS are around 2 amp/hour while the one I picked is 8Ah.

And that would be pretty easy to use.

u/Rich700000000000 · 4 pointsr/preppers

I have no idea why more people don't have a power inverter: You simply attach the clamps to a car battery and you get power.

They come in Low-Range, Medium-Range, and High-Range. You can even get an Industrial-Model for long-term use.


u/Bonneville865 · 3 pointsr/Triumph

I use this one:

https://www.amazon.com/Battery-Tender-021-0128-Maintain-Damaging/dp/B00068XCQU/

But this one would probably also do the trick:

https://www.amazon.com/Battery-Tender-021-0123-Junior-Charger/dp/B000CITK8S/

Should be able to find them at your local auto parts store, or even Walmart or someplace like that.

u/elislider · 3 pointsr/Cartalk

Shouldn't be a problem at all, batteries are made to be charged and discharged. Everyone should invest in a Battery Tender, they're really great chargers (and great for intelligently keeping a battery topped up for cars in storage). Not too much more expensive than shitty harbor freight ones, and they work and will last a long time.

u/Clapcheeks69 · 3 pointsr/kansascity

You pretty much have your question answered but I wanted to show some winter car accessories that I use and they have made life easier.

When my car is parked overnight I use a cover like this and it keeps ice and frost off your windshield. There are various types and sizes of these. Mine had side mirror pockets to hold it on and covers the wipers too. Putting in on and taking it off is much easier/quicker than defrosting and scraping.

Very cold temps can result in a dead battery, or one too weak to start the car. This happened to me yesterday and I used one of these to jump start it. I have jumper cables too, but with this I didn't need anyone's help.

When I got home, I trickle charged my battery with this. I just parked in my driveway and ran the charger's 25 foot cord under the garage door and clamped them onto the terminals under the hood. Started nicely today.

I also keep an air compressor in my car all the time. If I'm out on the road and my tire pressure sensors start beeping I can pull over anywhere and top them off.

You don't need a special thing. It's just a trickle charger with constant voltage charging.

u/seant117 · 3 pointsr/MechanicAdvice

You should be fine. Hook it up to a battery charger though. http://www.amazon.com/Deltran-Battery-Tender-021-0128-Charger/dp/B00068XCQU/ref=sr_1_2?ie=UTF8&qid=1422682919&sr=8-2&keywords=battery+tender

Those are great to own. Really helps prolong the life of the battery.

u/09RaiderSFCRet · 3 pointsr/motorcycles

Personally I’d consider selling it and get another when it’s time. Don’t you think it will sell for at least what you owe? Didn’t need payments or insurance when I helped raise my two boys, bought another later. But if you can’t decide and choose to store it, here’s an exhaustive checklist.

http://www.clarity.net/~adam/winter-storage.html

Here’s a great battery tender.

u/H2Oengineer · 3 pointsr/SleepApnea

I also have an AirSense 10 Autoset. The power "brick" provided with the unit is a conventional 120-240 VAC to DC converter. With the Ego Lawn Mower and Inverter you're converting electricity from DC to AC to DC. There will be substantial power-to-heat losses due to less-than-optimum efficiency of the power conversion.

Additionally, the AC output of the Ego Inverter (see manual, page 9) is limited to 150 Watts. At 120 Volts, this means that the current maximum it allows is 1.25 Amp. The maximum current demand that the AirSense 10 requires is 1.50 Amp. This is why the inverter's overheat is being triggered and it cuts power to your APAP; too much current is being demanded by the unit for the inverter's circuitry to handle.

I recommend following Resmed's Battery Guide using stand-alone, deep-cycle batteries.

I take my AirSense 10 camping and I recently purchased the following items, totaling to $205.56

  1. $68.99 12V 35AH Group U1 Deep Cycle Scooter Battery
  2. $11.36 Group U1 Snap-Top Battery Box
  3. $45.03 Battery Tender Plus 1.25 Amp Battery Charger
  4. $69.99 Rockpals DC Converter Compatible with S10 CPAP Series
  5. $10.19 Battery Tender Female Cigarette Adaptor for Quick Disconnect

    12V 35AH batteries ship factory-charged. If used with tube heating and humidification switched off, and maximum IPAP pressure of 16 cm H2O then a single battery will last you for two 8-hour nights. See Page 7 of Resmed's Battery Guide for details of power consumption if using any of the heat settings.

    I hope this helps. Feel free to ask me questions.
u/xj4me · 3 pointsr/Jeep

If it sits a lot then use a battery tender like this. You leave an adapter always connected to the battery then route it somewhere like the front grill. When you get home, plug it in if its going to sit a while into the adapter on the tender. That's it. It will keep it charged and ready to go. We use the smaller ones (not the one I linked) for the house generators out here and they work great. Still would be a good idea to start it and run it around the block every few months

u/karlmoebius · 3 pointsr/geek

http://www.jamesdysonaward.org/projects/micro-wind-turbine/

I'm always wary of someone promising me a thing without technical specs, or hooking up a multimeter to the output under either ideal (wind tunnel) or real life conditions. But in the most ideal method, to generate the stated 5w of power, that thing's spinning at ~10hz, and I'm not seeing it spin at ~10hz. While the closest solar panels are around ~1ft x ~1ft for the same max wattage. https://www.amazon.com/Sunforce-50022-Battery-Trickle-Charger/dp/B0006JO0TC

I'm also curious if it going to be anything more than an interesting concept, I expect that in october there's going to be a delay or a problem, and the next "new release" date will be sometime middle next year.

So color me skeptical.

u/nanan00 · 3 pointsr/collapse

I got two PM's about the battery/inverter rig so here is what I told others and a bit more.

I seem destened to live in areas with crappy power so when I moved to my new apartment and again found that the power here flickered like a candle in the wind I hit up CL and found a nice big APC backup PSU that had no batterys for $50($600 new), also on CL I found a set of two Exide sealed Gel cell marine Deep cycle batteries for $50 each($200/ea new). The system has run for 3 years now flawlessly, the computer will run for 7 hours on backup power.


When the hurricane hit I knew I could use the batteries to charge stuff with my inverter but they weigh like 80lbs so I wasn't about to drag them down to my car to charge them so after talking to a neighbor who is a boat guy I hit up a marine supply place down the road and picked up the biggest(that I could afford) solar charger, it was about $120, the next step up was over $300. I didn't think 20w would totally make up for energy drain so my computer use was very limited but I was able to keep my cell and ipod charged for the duration. I just hung the solar charger off my balcony(its a 2'x2' square of 4 1' square PV cells) and left the batteries where they were out in my storage closet on the balcony and ran an extension cord outside to it, the inverter runs on demand so I never had to mess with it. The inverter is a 1500w unit that I got from HomeDepot about 8 years ago to run some power tools at a camp site, it is way over kill for the use but given that I already had it oh well. If you just want to run a TV or computer you could get away with half or less wattage, heck a 500w unit would be fine for most non power tool or appliance uses and can be had for under $50 from radioshack.


The solar panel looks like 4 of these in a collapsable frame, the writing on it is all Chinese...

I don't trust anything but OEM chargers.

Were it me, I would definitely go with an inverter. It saves from having a specialized charger and allows you to use your home charger. The home charger would "level out" the power output (though modern inverters are pretty good) and make it safe to use.

The mag-safe chargers are 85W, so this would work

u/Baron_Von_D · 3 pointsr/boston

If you keep a power inverter in your car, you can run anything off of that plug.
I also have a jump box, which are great for many purposes. Some don't have a power receptacle but you can connect the inverter to the box and have a large portable battery that can be recharged in your car.
They are also good as a small power source for camping.

You can plug a [12v charger] (http://www.ebay.com/itm/For-Nintendo-3DS-DSi-DSi-LL-XL-New-Black-Rapid-Car-Charger-/112036859354?hash=item1a15eacdda:g:NP4AAOSwc1FXbI97) into the lighter socket, or you could get a cheap inverter that plugs into the same socket and just use a wall charger plugged into that. This way you could also plug other things in besides a 3DS. 75watts is enough for even the WII U.

u/Shnifty · 3 pointsr/RX8

Don't listen to this guy. WTF? If the battery is getting drained that has nothing to do with compression. The most likely scenario is an alternator issue. A brand new battery will work great until it gets drained and then it will stop working. What I would do is buy a $20 trickle charger and leave it on the battery. If it continues to start fine, it's because you're keeping it charged with the charger and that would imply that your alternator isn't charging your battery. I have had similar issues when not driving mine for a while because the battery will slowly drain over time from the onboard computer and alarm. My alternator works though so i just use the charger when I'm not driving mine.


This is what I bought and it works great: http://www.amazon.com/Black-Decker-BM3B-Battery-Maintainer/dp/B0051D3MP6/ref=pd_sim_sbs_auto_3


Seriously dude... why would this guy start saying scary things about compression when that has literally nothing to do with a constantly draining battery?



Edit: I missed the part about it not starting again even while jumping it. This is possibly because of flooding. If you don't let rotary engines warm up all of the way, they can flood. Best way to avoid this would be to leave the car running until it the temp gauge gets to the middle where it is straight up and down. I still think you main problem is the alternator though.


Another question I have is whether or not the engine is turning over or if your starter is going bad.

u/randolf_carter · 3 pointsr/AdviceAnimals

You would still need to plug the charger into an AC outlet. This is one I own that has an adapter for the accessory port.

Old fashioned bulbs are 40W / .34A per 100 bulbs. LED are 5W / 0.04 per 50

max 800 bulbs = 320W.

Since this is to be romantic event, I would suggest running the extension cord, or get a battery and a 500W inverter.

No motor running in the background to distract.

If using LED's you could likely run for a few hours. Regular, a hour, maybe 2 on a large car battery.

u/Scrabbydoo98 · 3 pointsr/aquarium

Get an Inverter like this one. Fill large bucket halfway with Tank Water. Move fish to bucket. Plug in Inverter into the car's cigarette lighter and add an air pump and a heater to the bucket. Plug air pump and heater into Inverter. Enjoy your drive!

For the tank itself after you have moved the fish to the bucket you can go ahead and drain the rest of the water from the planted tank. Then move the tank into your car. Once there just refill the tank and dechlorinate the water. Add the heater and air pump back to the tank and move the fish back into the tank once the water in the tank is back up to temp.

An Inverter may cost more than a battery powered air pump they can also be used for a lot more stuff. You can also get Inverters at almost any department store.

I didn't include a filter in the bucket since it's such a short trip. Don't really need a filter for two hour trip. If you were driving a long distance just add your filter to the bucket also.

I love my Spectra -- well as much as one can love a machine that sucks your nipples. I started pumping in the hospital with a Medela Symphony, and I get so much more milk with the Spectra.

I exclusively pumped for several weeks while LO was getting the hang of latching, so here are some tips:

I'd recommend getting a power invertor so you can pump in the car if you ever need to. I have this one from Amazon and it works great.

Prepare a "pump bag" to hold all your supplies -- hands-free bra (I have the Simple Wishes bra), pump, storage bags and bottles, permanent marker to label storage bags, a little container of olive oil to lube up my flanges (helps to prevent rubbing), small kitchen rags to wipe up milk, extra pump parts, etc. I use an LL Bean tote bag to transport everything.

In between pumps, I store all my pump parts in a gallon ziploc bag and stick it in the fridge so I don't have to wash them after every pump.

This may be a bad idea, but off the top of my head, maybe you could use a small inverter plus a battery tender to recreate a setup similar to your old one.

Edit: Also these are not cheap but there is a company called All In Charge that makes setups for charging your boat or RV battery while you tow.

u/myotheralt · 2 pointsr/motorcycles

If you know you are going to park the bike for over a week, put the battery on a tender. If you are parking for a week, usually it ends up longer.

u/LongUsername · 2 pointsr/geek

So the solution for camping and common power outages are pretty close to the same.

If you live somewhere where the power goes out often, get yourself a 12v adapter for your machine (varies by machine), buy a AGM deep cycle trolling motor battery (~$100) and a Battery Tender. Plug the battery tender to the wall, hook it to the battery, then hook the 12v adapter to your machine. Congratulations: the battery tender keeps the battery topped off, the CPAP runs off the battery, and you never miss a beat when the power goes out. If you're looking to lose power for more than one night (say you regularly have to wait out hurricanes) you'll want a bigger capacity deep cycle battery if you want to run the humidifier.

For car camping just leave the battery tender at home and turn off the humidifier. Fully charged battery should easily last you 5 nights.

If you're more of a backpacker/rough camper pick up a large USB battery pack that supports 12V out. People with Philips Respironics machines report that pack gives them 2 nights without humidifier. If you have a Philips machine it actually comes with the right size barrel plug, so no 12v adapter needed.

u/ChumleesCumRag · 2 pointsr/motorcycles

A good battery will bounce back and give you enough juice to start. Do that enough times and the battery says "F this. I quit."

Get yourself a battery tender and leave it plugged in when not riding.

Do you have a battery trickle charger at home? I would charge the battery for ~24 hours. I have one of these, and plug my battery in once a week.

u/Fulmario · 2 pointsr/Dashcam

The optima suggestion isn't going to solve the battery drain issue. Yes, it's a heavier duty battery. But if you keep pouring out 1/2 cup of water out of a jug and only replace it with 1/3 cup of water, you'll eventually run out of water.

Really needs to do a battery tender and get in the habit of plugging it in when they get home. A setup like this would be a good idea. http://s279.photobucket.com/user/NotMoneyGuy/media/IMG_3749_zps1edf0d2c.jpg.html

Have a quick disconnect say dangle through the grill of the car and plug the charger in nightly.

u/canurelaxwow · 2 pointsr/Justrolledintotheshop

Maine here. A good AGM battery and a smart charger if you're getting some extreme temps in the winter. My batteries are a few years old but they are still 13v and hold a charge like they are brand new. By no means do you have to charge the battery when you're not using it, as AGM's are much more resistant to the cold, but it's not a bad idea to charge it over the weekends.

u/fuzzyfuzz · 2 pointsr/motorcycles

I got my '15 PCX new in early 16 for around $3000 (if I remember correctly) + extra to build it and shipping fee. I think the build fee was like $100-$200 and another $100 for "shipping" it to the dealer. I think your getting an average deal.

Make sure the helmet you get is Snell certified. From what I remember the Snell cert is higher than the DOT cert. If this is your first helmet and you don't know what your doing, have the dealer fit you for a helmet. Its very important that it fits properly or it wont be as effective in an accident. When I got my PCX I got an HJC helmet from the dealer since I had no idea how to size one correctly. They are very nice helmets.

As far as bluetooth, make sure you read local laws. Some places make it illegal to use headphones while riding. Also, if your a new rider I would suggest not using them for a while and concentrate on the road.

As far as other stuff to buy, I would suggest a good jacket with pads and good padded gloves. If you hit the ground, you will be happy you had them.

Before winter, get yourself a small battery tender to maintain the battery while its in storage. If not, you may be buying batteries every year. My step dad has a Harley, never puts a tender on it over winter and wonders why he needs a new $125 battery every year. I got this one and it works great:

I use a 35ah deep cycle SLA battery like this one:

https://www.amazon.com/gp/product/B01HC57NXC/

SLA doesn't require any venting and works fine even upside down. They can also be left trickle charging forever, which makes a great backup if the power ever goes out. I get 3-4 nights at 14/18 on BiPAP without the humidifier. Humidifiers can be used, but it more than doubles the discharge rate. I still hook up the humidifier, but I leave it set at zero. This gives a bit of passive humidity. Your trolling motor box is fine. I use a toolbox with some plastic glued in to keep the battery in position. All the wiring can go inside (just like your trolling box), with a 12v cigarette adapter on the outside. This makes for a compact unit.

A voltmeter on the outside is really handy to know how much juice you have left. Also, I leave it charging all the time, so the voltmeter lets me know that everything is 100% ready. This one I picked up has USB too:

https://www.amazon.com/gp/product/B00QKDXB8E/

I use this cheap charger (The "Battery Tender" ones are recommended, just a bit more expensive):

I recently took a road trip with my mother (60), a 10 year old and a nearly 3 year old. We drove from North Texas, to Southern Ontario Canada and then to the Jersey Shore then back to Canada. Just under 4000 miles, lots of time on the road!

This made our trip a lot easier to manage.

My sedan only had two car chargers and between my phone and my mothers-not to mention the DVD players the kids had, the computer, our Kindles etc. I knew charging various things would be an issue. This one was around $20 and worked well. It has a fan inside, but I was able to put it under the seat while in use and the sound couldn't be heard.

You might consider one!

u/Piscea · 2 pointsr/DIY

you probably want to use leds for the lighting as you can very cheaply aquire and run some 12v leds straight off the battery without needing an inverter.

Same goes for a cell phone charger. Use a 12v car charger.

If those are the only 2 things you need to power you'll have plenty of juice in that battery.

Why that battery in particular?

If you're getting a solar panel you'll need a charge controller, and neither of those will be super portable anyway.

Consider a 12v 7ah sealed lead acid battery.

They are super cheap for their capacity.


As far as the solar panel, something like this would work.


it includes a charge controller.

I can run just about anything with this setup.

12v devices and wires can be connected straight to the "Load" terminals on the charge controller.

u/ItsBail · 2 pointsr/CampingGear

Has a much bigger battery, has an AC inverter. Only issue is the inverter is rated up to 120w. This mean you can run a laptop and other small devices but don't expect to get to run things throughout the weekend. Much better than what op linked. However w/ the panel it's almost 4x the price.

It sucks that the solar panels cost extra but if you were to buy now, the 25w panels are on sale. I would get two and hopefully get up to 50w (under optimal conditions).

It would be nice for car camping or a camper. If it's a permanent or even semi permanent installation, It would be better to purchase a larger panel, solar controller/charger, deep cycle large capacity battery and an inverter.

Ends up being a $270-$300 investment. That's not bad. If you were to buy the monoprice system w/ larger solar panel, it would be close to $300 and it wouldn't anywhere as efficient as if you were to make your own system. Only thing are sacrificing is portability and weight. A 8Ah battery will be much smaller and lighter than a 100Ah+ SLAB but won't last anywhere as long. If you have a rainy/cloudy week, good luck.




u/dharmon555 · 2 pointsr/musicians

Is that 15 watts of power consumption or 15 watts of output. A 15 watt tube amp will consume much more power than it puts out.

That unit will put out enough power to run an amp, but probably not for very long. It's designed to be able to dump a ton of power for several seconds to start a car but doesn't have enough battery storage to add up to any kind of sustained use.

Maybe an extension cord and find a kind soul that will let you plug in.

Maybe a 12v car battery (borrow one from some car or boat or something, big 12v batteries are everywhere and store tons of power) then get a 12v to 120 volt converter for relatively cheap.

This would work https://www.amazon.com/POTEK-Inverter-Converter-Charging-Smartphones/dp/B01B3ZQG4O/ref=sr_1_4?s=electronics&ie=UTF8&qid=1492750241&sr=1-4&keywords=inverter

and doesn't start your car or pump up your tires or other things you don't need.

Your play time would be limited only by how much power you consume and how much battery you've carted with you. With a small solid state amp and small mixer, expect to go for hours off of a car battery.

Edit:Another possible strategy I've sometimes used is to keep a car idling close by, put an inverter on it, then run an extension cable from the car over to the music. I've run a small band off of that.

Some people have meantoned that you need a pure sign wave inverter. This is absolutely false when you are using a charging brick. The ac to DC transformer in the brick will output the correct power no matter what.

I think you're fine on the battery / charging situation and others have already done a better job than I could explaining why.

I've got one with an air compressor, inverter, and lighting and I use the thing all the time around the house. The inverter portion is especially handy when you need power out in the yard for a project and the tire inflator has been used twice as much as the jump start function.

FUCK YES to making festivals a larger part of your life. One of the best decisions I’ve ever made :) I don’t know about the best shoes for dancing, but I always wear Vans to shows and festivals and I’ve never had an issue with my feet hurting. I think they’re a great option :) As for things to take the night of or after partying I would recommend a multivitamin, tylenol and a smoothie. The best thing you can really do to help yourself out is to eat lots of fruits and veggies in the days leading up to an event (or all the time!). Also constantly drinking water. I’ve tried a lot of extra supplements and misc. vitamins but they all are kinda extra and not needed to me. Also I constantly eating Cliff bars at festivals even when I’m not hungry. I feel better usually when I really really load up on calories. Healthier ones though!

Just bought this air mattress this year so haven’t tested it longterm, only used it for one festival so far. It stayed inflated well for the first 2 days and then we just topped it off with some more air for the remaining days and it worked great for us. Super comfy and it’s nice being higher off the ground. We put the air mattress in the tent before we inflate it, way easier. No air pump needed we use a car plug adapter and an extension cord. Its super easy to run your car for 5 minutes to inflate it. Make sure you pay attention to the number of prongs on your plug so you don’t buy the wrong adapter or extension cord too! For camping without a car nearby this method won’t work obviously but we always have the car by us.

My boyfriend and I purchased this tent 2 years ago and its made it though a decent amount of festivals. No signs of wear or damage. I know you mentioned a black out tent. I’m assuming to help sleep once the suns up? The heat usually gets me out of the tent before the light, it gets so unbearably hot once the suns up. You said you’re not new at this though so I’m sure you already knew that! :)

For staying cool I would recommend a cooling towel. Get it wet in your cooler ice water and it’s great to keep around your neck. Also small hand fans are a GAME CHANGER for guys and girls. It’s shocking how much they help honestly. Sitting with your feet in a small pool, bucket, or cooler when you’re hanging out at the campsite is super nice too. Just fill with water and some ice cubes and it really helps cool your body down!

I'd say forget what you see on youtube, thats some made up fantasy shit. If you try living on the beach prepare to be rousted every time you try to sleep.

Mosquitos will destroy you, be ready to deal with that. Mosquito netting over your bed area is a good idea(I use a king sized bed sheet and a clothes hanger rope over my cot). Also I have one of these I run if unwanted biting insects get into the van, I just full charge my battery before I go to bed and leave it on all night.

You will need a minimum of two 100w solar panels and a 100amp hour deep cycle battery if you plan to have any kind of electronics. I run a laptop(acer e5-575-338m) two cell phones and a 27" monitor on this all day every day. Once the sun goes down I unplug the laptop from the charger and can get ~6 hours off the laptop battery and the deep cycle will run my cell phone(internet) and my 27" monitor all night with power left over. The 27" monitor uses 28w of power(acer K272HL).

Currently I use this so I can have the panels out in the sun while I'm in the shade:

You will need a commode, I have tried them all and this works best in my opinion. Use either dirt or mix black water deodorizer in a gallon of water and poor it over the waste. Pee into a separate bottle, combining pee and waste is what cause most of the smell. Then tie off the garbage bag and put it in a gallon freezer bag and store that in a 5 gallon bucket from home depot with an airtight lid. This way you can throw out the waste with your regular garbage.

​

You will need the best cooler you can afford, ice is a serious pain in the ass to keep having to get every day. A Yeti knockoff will work and you can get one for under $200 but a dometic compressor cooler/freezer is best, but it will cost you like $800.

Another thing I found very useful is a salt shotgun for flys and other annoying insects(its a never ending battle). They make one you can buy but I made my own instead, you just cock the bolt pump it up and then use a funnel to poor a pinch of salt down the barrel. It will kill any bug you shoot as if it was hit by a mini shotgun.

I would recommend a cheap propane burner instead of the fancy coleman butane burners, personal preference but when I had the butane burner I would go through butane like crazy and its kind of expensive. Not to mention you can't always find butane in store but you can always find the little propane canisters.

​

Wet wipes are your friend.

Apple cider vinegar with water works for a diy sponge bath.

Keep a well stocked medical kit

Get a big can of bear spray or two for self defense, just know it won't work on mountain lions. I keep bear spray and a marlin guide gun for large animals(moose/bear) and a 9mm for two legged predators. I have had death threats and all kinds of crazy shit happen so just be prepared.

​

Locking gas cap is a MUST, lost one of my vans due to some asshole pouring water in my gas tank.

A Verizon phone with the cheapest unlimited tethering plan($70/mo), Verizon has by far the best coverage in the USA.

​

It is going to be hard, extremely hard, you will suffer. Don't expect it to be a vacation, its a survival skill not some pretend shit you see on youtube unless you have unlimited money to spend.

​

Gas will be your biggest expense, I spend more on gas that it would cost to rent an apartment. The only way to cut down on that is to find a spot you can stay long term(which is VERY hard, people do NOT want homeless guys in vans living outside there house).

For a MBP you’ll want to use a power inverter , something like this one. I think the 15” MBP has a 87w charger so you’ll just need one that provides in the 100w+ range.

A DC to DC charger would be more efficient, but if your only AC need is charging a laptop, the smallest inverter would probably work.

I spent a week in an RV “off grid” with the following solar setup to charge electronics and power electric blankets at night for warmth while sleeping:

Battery with three prong outlet plus USB charging ports:
https://www.amazon.com/gp/product/B01MA4YVNP/

NOTE: I paid $350 for that battery, but it looks like it is no longer sold. This one looks even better for $175: https://www.amazon.com/CHAFON-Upgraded-Generator-Rechargeable-Emergency/dp/B07142Z1XL/

Solar panel to recharge battery:
https://www.amazon.com/gp/product/B01N1FLGQO/

I paid $120 for the solar panel.

I don’t know if it is the cheapest solution, but it worked wonderfully and didn’t require ANY complicated integration, just plug together and done! If the solar panels did not keep up the charge, my backup plan was to run the generator built into the RV to charge up this battery, but it was never necessary!

This particular battery pack comes with an LED light, kind of a flashlight with a gigantic battery. I originally thought that was silly, but I ended up liking the feature for off grid living -> if you get up in the night and need a bit of light, toss the light switch and you can see what you are doing.

After my “off grid” camping trip, I turned the setup into a UPS for my computer, and it works great for that also. Plug the battery into a wall outlet, and computer into the battery, and when the power goes out, the computer still runs off of the battery for a few hours. I even used the solar panels to charge it back up during a 20 hour residential power outage a couple of weeks ago.

What I learned: normal computer UPS (Uninterruptable Power Supply) batteries are lead based which is heavy and clunky, and this battery pack is lithium ion so smaller and lighter. But lithium ion costs more for the weight savings.

By connecting an inverter to the 12v battery in the car. The 12v battery gets charged by the traction battery when the car is on and ready to drive.

I have a pure sine wave 300w car inverter like this one:

https://amazon.com/gp/product/B07KQ4Q2L5

I also have an adapter to connect it directly to the battery with clips, as the cigarette lighter jack in the car probably will not deliver enough amperage to run the inverter at anywhere near its full power output.

https://amazon.com/gp/product/B0759D724W

Both the inverter and the adapter are fused for extra safety.

u/tiekey613 · 2 pointsr/Herbalizer

I will cut off the cigarette lighter attachment, and connect directly to car battery via a fuse.

u/ocelotpotpie · 1 pointr/Ducati

Nah it's just a standard 12V battery. You don't need a fancy tender. Anything that connects to your connector will work. And all the ones I've seen come with the pigtail so you can yank yours and install it.

I like this one because it has a few more amps for quicker charging if I'm in more of a hurry:

https://www.amazon.com/Battery-Tender-021-0128-Maintain-Damaging/dp/B00068XCQU

But any tender will do.

u/BornOnFeb2nd · 1 pointr/diyelectronics

If you want to keep it permanently mounted, I would adapt influx's idea to a 120v signaling relay, that connects the wire between the tender and the battery. Plug it in, relay closes, tender gets connected. Unplug it, relay opens, tender can't pull juice.

Also, I don't know how many places you plan on charging your bike up but the Delran tenders have detachable cables. When I want to put it on the tender, I untuck the cable from the storage compartment, plug it in, and when I'm done, unplug and tuck again.

u/CaptRon25 · 1 pointr/motorcycle

Get yourself a Deltran battery tender

u/gunslinger_006 · 1 pointr/sportster

Verify your stator is healthy before you throw a new battery on your bike.

Do you keep the bike on a battery tender when you aren't riding it? You definitely should.

As for batteries, any AGM battery will do fine. The very best batteries are the Lithium Ion models from Shorai, but they are VERY expensive (about $150-$250), but they deliver massive cold crank amps which is exactly what you need, especially if you are trying to start a 1200 conversion with the 883 starter/gearing.

  1. Verify your stator is putting out the correct volts across the entire RPM range. Your service manual will have the correct voltage values for various points in the RPM spectrum.

  2. Start using a battery tender.

  3. If you decide to buy a new battery, any AGM battery will be fine, but you really should consider saving up for a Shorai Lithium Ion battery, as it will meet your needs and then some. Here is a direct link to the Shorai battery for your bike: http://shoraipower.com/products?action=vehicle&type=175&make=941&model=7529&year=7529 It is $250, which I know is a lot to spend on a battery. It also puts out THREE HUNDRED AND SIXTY cold crank amps which is enough to start a big block V8.

  4. Also verify the resistance of your plug wires and the health of the plug boots and the connections between the boots and the coil and the boots and the spark plugs. I doubt a hotter ignition module will do much good for you, but its possible that your current plug wires are not as good as they used to be and if the resistance is higher due to internal corrosion...that can suck away juice that should be getting to your plugs.

  5. Verify your carb is healthy and in good working order. When was it last cleaned?

  6. Inspect and gap your plugs, or just straight up replace them if its been more than a few years.

Yeah, everyone who wants to maintain their battery (especially for storage and through cold weather) should put it on a battery tender. $40 will save you a new battery and many headaches.

That probably is the most feasible solution. My only question with that is if I use an inverter like this, can I gut it and remove the fan? Or will passive cooling not be sufficient for long-term use at 5 watts?

This ships from Hong Kong, so be patient if you order, but I have made dozens of orders through DX over the years and they are great.

Alternatively, you can buy a small inverter and plug your wall charger into it. This is what I did on a week long road trip last week and it worked great even though it is a little hokey to convert DC to AC and then back to DC.

Mine is about 7 years old, but this one from Amazon has a 2.1 amp USB port as well as the AC outlet. Shop around, but this is the popular one that showed up in an Amazon search.

Are you going to be using them in parallel for 12v or series for 24 volt? If your end goal is 70ah of 12v you can just connect the charger to the batteries positive and negative respectively with the two batteries still connected together.
If you dont plan on draining the batteries much or don't mind longer charging times something like
this will work just fine. If you want faster charging time or plan on draining more amps out of the batteries then I would buy one of the higher amperage charger offered in the link.

u/Lost_electron · 1 pointr/batteries

Some batteries will show a C rating. That's the charging rate relative to the battery capacity.

For instance, I have a 7.2Ah battery that mentions a 0.3C charging rate. That means that I should charge it at 7.2Ah * 0.3 = 2,16 amps.

15 amps is probably too much for a 18 Ah. From what I see online, a certain battery mentions 5.4A max. Yours should be around that, too.

Plus, most modern deep discharge SLAs are AGM (Absorbent Glass Mat) and will need a bit more voltage than car batteries. Mine should be charged at 14.7V.

For that reason, I would suggest using a charger designed for AGMs. I have this one that can charger both my car and my AGMs and it works well.

Feel free to ask any question if you have some :)

u/redditmemehater · 1 pointr/MechanicAdvice

That was my worry.

I have a "smart" battery charger linked here but it refuses to start charging unless the voltage is above 1.8V. I have read in the reviews that it might require at least 3V to understand what battery it is dealing with.

Thats why I was asking if there was any charger that would trickle charge it manually to get it up to a higher voltage. Like would something like the famous "Battery Tender Junior" work?

What would you say if I were to just jump the battery from the portable charger that I linked, run the car for 10 minutes just to get a little bit of voltage, then use my slow "smart" charger to slowly charge the battery over the course of many hours or days.

I feel like this will put the least amount of strain on my battery, prevent me from having to risk some other car, and not have to undo the battery, its bolted bracket, and lug it somewhere.

What is your honest opinion on this course of action? Do you think the alternator and\or dead battery will suffer severe damage from this plan?

Power / Inverter Question:

With out going into too much detail, let's just say my rig will be connected to shore power on most excursions, call me a weekend warrior.

Somewhere down the road I will probably add Solar but that is not within the next 1-2 years.

When connected to shore power my LED lights would still be on 12v power. So here we go...

​

  1. If I am on shore power I can get an all in one inverter / charger to keep power to my batteries and my LED lights. Could I go even cheaper and just have my 12v batteries topped off by a battery charger such as a NOCO Genius ? Reason being it only needs to keep the battery charged for the LED lights. It would also then allow me to spend the budget on the best Inverter, and solar would eventually be what keeps the 12v battery charged in the future.

    ​

  2. How long can you run LED's on battery? I know this is loaded as there are tons of factors in play. But I'm wondering if I even need a power solution like the one mentioned above if I only plan to run 6 LED's that say 2W on the package. I'd really just need them to last the weekend until I drive the rig home.

    ​

    Thanks!

Your solar panel produces DC energy while a charging station offers AC energy for a different type of charging system.

You could bypass everything and use a conventional battery charger. What type of battery(s) are you charging?

u/banzaiburrito · 1 pointr/amateurradio

THD is total harmonic distortion, basically if it's over a certain point it begins to affect the sound quality.

The easiest option for power is a standard lead acid battery, they're a bit heavy and large but are also safe and cheap.

Here's an example.

And because they are standard you could use a small car charger to charge it up like this one.

u/silverfox762 · 1 pointr/Harley

If the bike is going to sit for months at a time, get a tender, but you should be able to find a good one for $20 USD or so. They all charge the battery the same way to the same 12V+ level, no matter what brand. I bought one from Black and Decker for $20 USD since I now have two bikes and one sits for longish periods.

u/EorEquis · 1 pointr/astrophotography

IMO, any and all of the "power stations" are overpriced.

It's just a battery...in the case of most of the "power stations", it's not even a very good one for its task.

You could :

Find a 35Ah (twice the capacity) deep cycle (superior technology for what you're using it for) battery for about $30

Buy a nice red LED flashlight for $5-$10

Throw together a power distribution panel with whatever types of plugs you like for $20-$30 or so.

Finally, for our purposes, any reasonable 12V battery charger will do.

Now you've got twice the capacity, all the same gadgets, customized hookups that suit your needs, and you've spent $50 less. :)

u/ChunkyLug · 1 pointr/Harley

First, check to make sure the battery connection is tight; second, check to make sure battery has a charge; lastly, do you have fuel? When the bike is parked, keep it on a trickle charger. Attach a pigtail to your battery so you hook it up easily when you get home every night. If you're getting a click-click-click when trying to turn it over, it's probably the battery. I bought this trickle charger a while back and haven't been sorry at all. It also comes with a pigtail. Good luck.

First off, whoever said there isn't a drain on the battery could easily be wrong. Cold temps dont drain batteries, it just reduces the battery's potential output current. A cold battery cant put out as many amps as an equally charged warm battery. If there is a drain it can be really hard to find, you basically need to monitor the drain on the battery while disconnecting one thing at a time to see what makes the drain on the battery drop down to where it should be. Try turning on the headlights for a few minutes before trying to start the car, if the problem is that the battery is too cold to push the amperage you need to start, that might warm the battery up enough to start the car.

if the headlight trick doesn't cut it, you might want to get a battery charger, it will continuously trickle-charge the battery so it stays fully charged throughout the winter. I would ultimately recommend that you find someone who knows how to diagnose battery drains, but this could be a decent way to handle things in the meantime.

here's a cheap one I found on Amazon

You're good on the kickstand, just roll the bike forward a few inches every few weeks so the tires are not always resting on the same spot all winter. Also, you can pick [this Black and Decker] (https://www.amazon.com/Decker-BM3B-Battery-Charger-Maintainer/dp/B0051D3MP6) tickle charger up for $20. If you don't have the $23 to spend to get a trickle charger, well you mentioned Christmas gifts. Ask for one and wait another 25 days.

u/Froggypwns · 1 pointr/NoStupidQuestions

This would be fairly simple to do. You would need a power inverter to convert power from your truck's 12v system to the 120v the projector needs. The link you posted shows it uses 50w of power, so it is in the same ballpark as a laptop. Power inverters come in all kinds of shape and sizes, depending on the number of outlets or watts you need. Smaller ones plug right into your cigarette outlet, bigger ones need to be tied directly into the battery. Also before buying anything, find out if your power outlets still work once the truck is off, on some cars the outlets are on 24/7, some only with the key on. If your truck requires the key on, either you will have to leave the truck running or hook directly to the battery.

I have no experience with it, but this one is highly rated, and can attach directly to a battery or your cigarette outlet - http://www.amazon.com/ENERGIZER-Inverter-cigarette-lighter-compatible/dp/B00ATXERNO

One thing to be advised of is that running these will drain your truck's battery, I can't say if 2-3 hours would leave you low enough to not start the truck as it depends on how good the battery is, but it is a possibility. If you have another battery you can borrow, maybe use that. Another option is to bring a portable jumpstart pack ( http://www.amazon.com/Anker-Portable-Advanced-Protection-Flashlight/dp/B010DP8PIU ), I have this one and it has saved my bacon before. I recommend having that in your glove box regardless

u/securitywyrm · 1 pointr/electricians

Okay so... let me see if I'm doing this right.

Assuming this power inverter: http://amzn.com/B00ATXERNO
And this device: http://amzn.com/B0061FSZZ0
Hooked up to an SLA battery (Link needed)

The device would have plenty of power, because the inverter can put out 500 watts, and the bubble machine uses 45 watts. So even factoring in the 25% loss, this kind of setup could easily run 6 or 7 or those bubble machines until the battery is depleted, correct?

I ask because I'd like to put more on the machine than just the bubbles. I'd like to upgrade it over time to two bubble machines, lots of lights and perhaps even a small fog machine. Again, weight is not an issue because we can pass it between performers.

u/Snops1017 · 1 pointr/audiophile

So this weekend I plan on playing music through speakers and a laptop power through my car. I am using this which has a stated output of 200W Rated, 250W Max, 500W Peak (AC). The speakers I am using are LSR305s which have an LF Driver Power Amp 41W Class D and a HF Driver Power Amp 41 W Class D. I am using two of these and at times I'll need to charge my 2012 Macbook (simultaneously maybe) which uses a 60W charger.

I'm kind of lost looking at all these numbers. For example, do I add the LF and HF amp and multiply by two an add the charger wattage? The back of the LSR305s say 127W Max, is that at full volume?

u/rknw · 1 pointr/VisitingIceland

-- If you email them they can answer your questions about the inverter, and that might be a good idea because it can vary from what's pictured, but the pic looks like it has one USB port and one plug port for European plugs. I brought my own inverter, this one which has 4 USB ports and 3 US outlets. The red version has better USB ports (4x 2.1a instead of 2x 2.1 and 2x 1a). With this I never needed to look for an outlet to charge any of my gear.

-- The stoves are usually butane fuel and come with one bottle. On my trip fuel was readily available at gas stations and some campgrounds. They may have supplies from previous renters you can pick through as well.

-- I bought all my food there (my van had a fridge) so I'm no help on this one.

The Schumacher will certainly do the job - but for [$125 you get to carry around 24 lbs. of 22 amp hour battery and a compressor] (http://www.amazon.com/gp/product/B004EIAADG/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B004EIAADG&linkCode=as2&tag=battleforthew-20). The thing is so heavy that I hate carrying it back and forth to the car after I charge it up in the garage.

I bought this thing 3 years ago, and it has served me well, but I wouldn't buy it again now that lithium batteries have come down so far in price.

u/SVKissoon · 1 pointr/vandwellers

Do you have a recommendation for the inverter? A part of the appeal of the Krieger was that there is an LED readout showing the input and output, and the dual USB ports. The closest thing I can find is the same inverter in 1100 watts.

I think the roof rack is the way to go for securing the panel as well. That will likely be the way I go. Im thinking of going with crossbars as Id like to put in a rooftop fan vent as well, as soon as I get the guts to cut into the ceiling.

As far as the charge controller, do you think the low cost of a PWM controller is worth the power efficiency offered by an MPPT controller at a higher cost? This is just based on things Ive read in my research.

And I am using a 2013 Toyota Tacoma with a 4cyl. you can try to hook up a second battery. But I am not sure how much room you have under the hood to do that. There is plenty of room in a Tacoma and many overlanders mount 2 batteries. But it the kit to do that is several hundred dollars, and is more than I want to invest in.

You could also use a buck DC converter to step down the voltage to dim instead of a dimmer like that which is PWM. PWM is more efficient, but be aware that if the dimmer's PWM frequency isn't really high (10Khz+), you will see flickering/banding in any video recorded from the lighting.

Here is a buck converter that uses a little screw to step down the voltage as much or as little as want. As long as the DC voltage out is less than the DC in, it can step down. This type of converter wont affect any video/photography since its not PWM.

That one does have a built in current limiter that is controllable ... so you need to make sure the output is 12vdc, and the current out is either unlimited or 1amp or more... It is possible to starve a fan for current and slow it down

If you really want to be sure you have enough power to charge your batteries and phones, consider picking up a spare car battery and an inverter that'll hook directly up to it. Something like this:

Yes it hooks up to your car battery. Your fridge/freezer mostly likely pulls 800+ watts, a direct 12v inverter will be necessary. This wiring kit comes to set that up to the inverter. They were really popular during hurricane season. https://www.evextend.com/Emergency-Power-Kit.php
Bit of a sticker shock on the price, but in my experience with car stereos which require a similar set up, it is not outlandishly expensive.

Cigarette lighter circuit for sure won’t be able to power any fridge greater than a mini fridge, which this inverter can do if you’re interested.
