Hello. I want to try a power bank with a raspberry pi, but will it break it? I looked up the correct voltage to use, but I am still a little conserned.
I'm not sure if the Pi4 models still have this special USB jack issue, but in theory you should be able to use a power bank as power supply. For recent pi models you will need 5V/3a to power up the device and have some overhead for periferals. I once tried with a Pi3 model using a power bank which had around 26.000 MAh, the Pi ran for about two days before I had to recharge the battery.
