Reddit reviews Jackery Portable Power Station Explorer 240, 240Wh Backup Lithium Battery, 110V/200W Pure Sine Wave AC Outlet, Solar Generator (Solar Panel Optional) for Outdoors Camping Travel Hunting Emergency

A battery does not have to be special built just for a CPAP, any battery that provides 12-volts DC will work (which is the same type of power your car battery provides). CPAP specific batteries are a scam. You just need to get the right DC power cord for your machine and hook it up to any 12-volt battery.

Now how many days will you need, and does your battery need to power anything else? Do you need it small enough to be legal to fly with (limit is 100wh (watt-hours) or 160wh depending on your airline).

The smallest and cheapest solution is the Easyacc Portable Power Bank 38000mah rated 144wh and costs $81. It is the size of medium paperback book and about 2lb. It has a built in cigarette outlet, usb ports, and a built in white light plus flashing red emergency light. Using my Dreamstation (without humidifier) it has enough power to give me approx 4.5 8-hour nights. Best of all, it's still under the 160wh limit the FAA has so it's legal to fly. It is also about 50% more capacity of a CPAP specific battery which are typically only 99wh.

Going larger you have the Renogy 222WH Laptop Power Bank or it's bigger brother the 266wh

If you need a built in inverter so you can get normal 120-v AC power (which will drain your battery quickly) something like the Jackery Portable Power Station Explorer 240, or Jackery Portable Power Station Explorer 500

There is also countless other chinese knockoff style power banks available. Most of them will be perfectly The only thing I would stay away from is anything that looks like this because they do not actually have a cigarette outlet (you have to get a barrel to cigarette adapter) and they tend to be actual garbage systems.

The gold standard for battery systems is the Goal Zero Yeti 400 Lithium Portable Power. I happen to also own this and it provides me with enough power for over 11 nights of power on my CPAP and still wasn't completely drained. It also comes in larger sizes. It is the most expensive option but the best designed. Weighs about 11lb, and can be charged pretty much from any solar panel big or small.

Other people will say the best thing to do is buy a lithium mobility scooter battery and build it yourself. Which I feel is only a good answer if you are handy wiring electronics. Some people just want a prebuilt answer.

These "solar generators" or whatever you want to call them are coming down in price. They are not enough to run major appliances but it can give people an option to run lights and charge phones if you cant run a generator. Can recharge them during the day with a solar panel so its good to go again at night.

I just finished building something similar that can run 2 cpap machines for a night, was kind of looking forward to testing it today if the power goes out. So far no outage in Dartmouth.

That model is likely overkill to charge ~50%...sounds like you really only need a small top up (20% or so) to get you back home under power:

This one would almost certainly get you what you need to get home under power:

I suspect this would get you 15-20% increase in charge over what you pulled in from your commute with.

if you wanted to go with one of the hefty jackery ones, this one would likely get you 60% from 0 or more charge into the battery of the rev (67k mah):

no need to spend 425 USD.

PS: this one is crazy cheap and would likely charge you to at least 60% from 0 (great reviews to boot) - at 64.8k mah slightly less mah than Jackery hefty one, but nearly identical spec wise, and much cheaper:

I may even give that a go for the price!

Source: I own this one and it charges my rev from 50% to about 95% (42k mah, while the two bigger guys above are around ~65k mah):

I can't recommend the one that I own...had some issues with it.

You’re not going to find an affordable battery, and certainly nothing that you can support with Velcro, that can run that stuff.

There are “battery generators” that are designed for tailgating and camping but they’re not small, and the ones that are, aren’t that powerful.

Here’s an example; it has a max 200W output. My little Krups coffee grinder pulls 110W according to the label. I’d guess a juicer to be more like 500.

I think it would make your life worse, not better, to have to charge your kitchen every night.

They have ones that passthrough when they are being charged specifically for dashcams, they're expensive (Celllink B comes to mind). And the solar batteries are specifically meant for passthrough, but they are SUPER expensive. Something like this combined with some panels.


Edit: Celllink B only lasts ~20h. A big solar battery would make it a few days, would need to be charged at home I think.

I have and use one of these - Jackery Explorer 240.

In my case though, this is NOT just for charging phones, I unfortunately need a CPAP machine, which this will power for a weekend. Also, I use it to power the fish finder in my little boat.

Yes. Jackery has solutions for this that people have posted great results with. both 12v and 110v capable, both are commonly used for pellet grills while camping/traveling.

Sorry no idea. It shouldn't be so difficult to reproduce the id signal, but I'm not aware of anyone in this business, so there is only the Dell 18000.

USB-C PD seems a natural alternative, but 60W+ are rare and costly. Should go up to 100W, but search for 100W mostly finds crowdfunding projects ;) The circuit gets much more complicated.

Should I get something like this for recharging my phone/laptop? https://www.amazon.com/Jackery-Portable-Power-Station-Generator/dp/B07D29QNMJ/ref=mp_s_a_1_3?keywords=camping+battery&qid=1566344296&s=gateway&sprefix=camping+batt&sr=8-3

not sure what the recharge rate is but i would imagine unless your directly tethering to the terminals then you would be limited to the fuse amperage, typically like 15 amps on a cigarette plug i think?


back on the main topic, maybe something in this article might help? https://teslatap.com/articles/12-volt-battery-compendium/ they dont mention exact rates that i saw but it says "

>The Gen 2 DC-DC converter in the refreshed Model S accepts 220 to 430 VDC at 15 amps, and outputs 9 to 16 VDC. When outputting 12 VDC, it can deliver about 200 amps.
>
>The Model 3 integrates the charger and the DC-DC converter into a single package, the PCS (Power Conversion System)

​

IMHO i would just invest in one of those Portable power stations from the likes of Jackery, Anker or Goal Zero especially seeing as how the replacement battery is going for about $500 on Amazon.

I found this pump.

Could I connect a panel and the pump to something like this?

Could look into getting something like this. But the insulated pump thermoses are pretty awesome, too.

How is that on battery life of car? If I used it 3> hours should it be fine? I was looking at portable charging stations, how would those work in a vehicle? Ex: power station

Thank you so much for your detailed reply!! I really appreciate it.

So I went ahead and got an electricity usage meter so that I can see how much power the devices I plan on taking with me will use. Like you said, this will allow me to better plan my setup. I should have done this first actually.

Another setup I'm considering is a power generator similar to something like this. What I'd like though is that it has 2 inputs for charging: one from the car and one from the solar panel. I don't want to be having to change inputs when I drive, and then change it again when I'm stopped. Most of the power generators/stations I've seen only have one DC input though. I tried looking for a male to female DC splitter but the ones I've found I don't think are strong enough to run the current from the two charging sources simultaneously.. the only one on Amazon I found is 22 AWG, which according to wikipedia can handle at most 6-7 amps. Did I understand that correctly? Does a DC splitter with a lower AWG even exist?

Another feature I'd like is the ability to use the generator while it's charging, but unfortunately even here most of the units I've seen cannot do this.

I'm going to wait till I have a better idea of the max amount of power I'll need before I research this again.

Thanks for the advice on how to run the fridge efficiently btw. I didn't even consider this. Those are excellent points. Also your idea on the passive water supply for the evap cooler, that's brilliant! I'm going to try fitting that into my design. And I say this bc it can't be that big, but I can perhaps have a half a gallon bottle..

In Canada it's also on sale ($390 CAD - $25 coupon), but not as nearly as good as US sale - https://www.amazon.ca/Jackery-Portable-Power-Station-Generator/dp/B07D29QNMJ/ref=as_li_ss_tl?ref_

amazon.COM doesn't ship this product to Canada, at least to my location anyways...

I apologize,I had been thinking of something like the Jackery Portable Power Station Explorer 240 which I misremember as 240 amp hours rather than 240 watt hours. They also make a 500 watt hour model for ~500 dollars. That’s probably two recharges a day for most mini fridges with the 240.

I did find this fridge the Ausranvik Car Fridge Portable Freezer which uses 32watts DC when it runs apparently (and won’t run all the time) so except in the hottest weather it should keep you on once a day recharge, or a few days with a big block of ice.

You could also lean on friends in the dorms to keep a big jug of water in a communal freezer for you and swap it out every few days.

Something like that? I always just suggest not spending anything to do with charging limes, thats just a cost youll need to recoup before making profit.
