Powering gaming Raspberry Pi 3 and official Touchscreen

Mon Mar 12, 2018 6:48 pm

Hiya

So I am running a Raspberry Pi 3, with an official 7" touchscreen, in a nice case that I got. Now I want to power it with a battery/phone charger. I have tested with a couple of the small chargers as below, but that gave me 1hr 43 min, and another about 2hours

Can any of you lovely people recommend a good powerbank/phone charger that will give me maybe 4 hours life to power the screen and the Pi ????


Thanks in advance

What was the mAh rating on the one that gave you 2 hours? Or better yet, if available, the wh rating.

Find one that has roughly 3 times as much and you should be okay. Beware that you may want a powerbank that can sustain 5v while supplying ~1A or more.

Don't blindly trust the numbers on the sellers page though, they're usually misleading and some are outright blatant lies.
Tip: 20,000mAh will NOT fit in your pocket.
