Does anyone know of a recommended battery or power bank for the Raspberry Pi 3? I would like to be able to bring my Pi 3 along with me. I know that the Pi 3 gobbles power very fast but I want something that stores power enough for a decent amount of time. I also want something that is a little slim and not enormous and chunky allowing me to carry the battery and the Pi with ease. Does anyone have suggestions on different batteries for me?
You can use any cheap battery powerbank for charging mobilephones. I suggest you to use some powerbank caapble of supplying at least 15000 mAH or more. But if you draw too little current out of them (100 mA or less) the baattery pack may go to sleep mode. Cutting of supplying power to your raspberry. To prevent this there's a little circuit here: http://www.dorkbotpdx.org/blog/paul/battery_pack_load
