There are three different sizes - S, M, and L. I got the M (the one for Samsung Gear VR).

As for battery pack, I don't have mine yet. But I have this one on order, and should receive it tomorrow: https://www.amazon.com/gp/product/B005NF5NTK. I expect that it should easily fit in the case with everything else.

Just go third party: http://www.amazon.com/gp/product/B005NF5NTK

It has twice the charging capacity.

Second the motion. USB batteries are a dime a dozen, but they aren't all equal. Anker makes the best batteries IMNSHO. They have sizes ranging from a little lipstick-style battery to a monster battery with more power than anyone needs. I have their penultimate battery with only 20,000 mAh of juice, and I've never run out of power.

Anker also makes the PowerLine+ cables, which are the only third-party cables I'll buy these days. Cables aren't complicated, but it's important to have good ones.

It's a battery charger for iPhones and other USB gadgets. Handy for when you need to charge something and don't have an outlet nearby.

Strap the battery somewhere to the headstrap. That should mode than double the runtime.

You could grab this portable charger for only $20 http://www.amazon.com/dp/B005NF5NTK/

Here is what I typically carry on a normal day.

• Backpack:
  
  
• 15" MacBook Pro
  
  
• iPad Pro + Smart Keyboard + Apple Pencil
  
  
• Classic moleskine notebook
  
  
• Extra small hard cover moleskin notebook
  
  
• "Write drunk edit sober" notebook
  
  
  
• Parket ballpoint pen
  
  
• Beats Studio wireless 2.0
  
  
• Anker Astro Mini 3200mAh battery
  
  
• Foam ear plugs
  
  
• iPhone 6s
  
  
• Leather wallet (not sure what brand)
  
  
• Classic chopstick
  
  
• Car keys w/ gym pass
  
  
• Knife (not sure what it is, found it at a yard sale can anyone identify what it is?)
  
  
• 42 SS Apple Watch
  
  

You can get a range of sizes depending how much you'll need to charge. The smallest one below is enough for one full charge of most phones.

Edit: Swapped out the big one with a newer one...

I have one of these, and it works great. Provides more than a full charge for my iPhone 4S, and is very portable. I don't use it much anymore though, after buying a case with a built-in battery. The case is just a bit more convenient.

i was able to fit a fury 2 (with cover on), a external battery with cable ( https://www.amazon.com/gp/product/B005NF5NTK/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1 ), a doob tube with ground up bud, the brush, and a plastic bag for abv all inside this smellproof pouch: https://www.amazon.com/gp/product/B01M0X9B5E/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

it was as mobile a setup as i could assemble

get a couple of USB Chargers. You'll be able to use them to give your computers some more juice when batteries get low and recharge everything at night. I think one of these will recharge an iPhone 2 or 3 times without being recharged itself.

I found this

I always had good luck with Anker or Limefuel they hold here charge a pretty long time and have more juice then you know what to do with. I dont own a RAVPower but my friend does and has good things to say about them and there the most bang for your buck. Basied on the amazon reviews dont get with the one you linked it seems to be fake... Also consider getting a lipstick changer for when you dont feel like luggin that big o pack around something like this Anker or this RAVPower that also has a great built in flashlight that my sister loves.

I think these small synths that double as controllers are often used in music production (or even on stage) where they are powered by a host computer. It can be powered by a cell phone charger through it's USB port. I think an increasingly common assumption is that cell phone chargers are readily available for anyone who needs to run small electronics off a wall outlet. I have small computers that didn't come with AC adaptors for that reason.

It doesn't run off of built in batteries. However a mobile booster/charger should easily power the Korg. Anker has a good reputation.

https://www.amazon.com/Anker-bar-Sized-Portable-High-Speed-Technology/dp/B00P7N0320/ref=pd_lpo_107_bs_t_2?_encoding=UTF8&psc=1&refRID=9XTN1NX6H6K78V79CAE8

There are lots of larger battery powered portable keyboards with built in speakers similar to this Yamaha but the small controller/synths are usually powered by a host computer or an AC adaptor. Built in speakers in something as small as the Korg couldn't be very good.

Ultimately I chose the XKey I mentioned which is powered by my iPad. However before settling on that keyboard I was also looking for something small with built in sounds. The choices of small instruments that were battery powered was so restrictive I decided I'd need something like the Anker booster for portability.

I am going with this guy for size and weight. It's $10 in black, worth a shot. Will charge your phone one whole time.

For power consumption ill have a sansaclip+ for music on the trail. My USB cable, wall adapter, maybe even my phone will be in my bounce box.

In terms of brand I personally have an Anker first gen 10000mah that does charge my phone but no way I'd carry it with me all the time. It actually does 2xUSB but also 9V and 12V DC which I use to power my DSLR camera for like 8+ hours.

They do have an Anker Mini which is the small round size in 3200mah.

Another popular brand is Intocircuit known for their Powercastle, but again they have a mini tube as well.

Prices can range from $3-$30 for those small ones, with varying capacity. They are all just various 18650 cells (ranging in quality probably), a plastic shell, and a usb thing that lets you charge it.

Amazon will have many, reviews will most likely be telling of quality.

This ankor astro mini! Because I can definitely count on my phone to be drained whenever I need it most. Thanks for the contest and happy cakeday!!

Anker makes some of the best stuff, very solid and reliable. I like this one (also have bigger ones): http://www.amazon.com/Ultra-Compact-Portable-Lipstick-Sized-Technology-Smartphones/dp/B005NF5NTK

Say "hello" to the portable charger.
