Battery for Raspberry Pi 3?

post #1 of 10
Thread Starter 
I am looking into making my Raspberry Pi 3 portable. Are there any batteries that would work well with it? Honestly, i am wanting to make it portable to charge phones due to it's 4 USB ports on it.. Which, of course brings up the second question. Would the USB ports on there work well enough to even charge a phone? Id'e also hope the battery life if it does charge won't die super fast.

If you'd get a nicely shaped laptop battery with a converter to 5v, you could plug it into your Pi and charge things with that. Battery should last quite a bit too.

You just need a way to charge that battery, so buying an old laptop that works enough to charge the battery would be ideal.

Interesting idea but I'm using this: https://www.amazon.com/dp/B009USAJCC?ref_=ams_ad_dp_asin_1

It powers the Pi just fine and has an extra port in it if you wanted to charge a phone as well. I'm not sure what capacity you are looking for but I just wanted something small so I wasn't fumbling with it. The only complaint I would have is this backup battery touts itself as adaptive, so when the Pi ramps up the demand you will get that little rainbow square in the corner indicating a low power source. It still functions just fine though.

Regarding "... looking into making my Raspberry Pi 3 portable"
if you have a spare UPS (e.g., like the ones ISPs sometimes give you when you get Internet service),
then you could use it - it is a battery with power regulation circuitry.

I have a couple of these Romoss-brand USB batteries for powering Raspberry Pis. Cheap and effective.
