  • Looks amazing. I'm sure lots of people would like to know how long a RPi can (really) run off one of those. Commented Mar 12, 2013 at 6:16
  • Looks good. Specs say: USB Output: 5V / 0.5A~2.1A Max output: 3.5A It has 4 ports, so say just over 1.5A per port you could in theory run four Pis from it. If anything, I would say it's overkill for running one Pi. At a max of 3.5A There shouldn't be a problem running a Pi with various peripherals plugged into it.

  • Just had a look in the comments on the product and people are using it to power a Raspberry Pi. One enterprising guy is even running the Pi, a wifi dongle and a Liliput screen off the battery. No word on how long it will last, but you've got to figure 9 hours at least for just running the Pi and a dongle off of it. Apparently you can also hot-charge it so you can charge it from the mains at the same time as running the Pi off of it. Very nice indeed.

  • @Raspberry_pi_eater Have you solved this issue yet? If so, could you please either mark the answer that solved it or create a self-answer with what you did and mark it as such. We are trying to get the site Q:A ratio up and that would be great. Thanks! Commented Mar 3, 2014 at 17:18

Have a look at this USB battery pack.

I found it when I was looking for an 10" LCD for my Raspberry.

It seems some people already tried it.

I got the USB battery pack mentioned above (EasyAcc 12000mAh External Battery Charger Pack)

When the pack is 100% loaded, my Pi runs about 13-15 hours (headless, w/o usb devices)

  • That's pretty darn good if you ask me!

Battery packs are good, but when they're dead they don't let the Pi know. So the Pi dies and you risk SD card corruption. Anyone else remember SCANDISK or NTFSCHK? That, but worse.

The MoPi board takes pretty much any battery and powers the Pi with it, without the risk of sudden cut-off. They get 8 to 10 hours on 8 Ni-Mh 2600 mAh AA rechargeable batteries.
