Intocircuit Battery Bank on Amazon: br The Intocircuit 3,000mAH battery bank is a travel sized battery bank that can give your phone the extra charge that it might need to get throughout the day. This battery bank charged my phone from 0 to 90-100, depending on usage while charging. It also comes with a USB to micro USB cable and a nice little traveling pouch. A really nice added feature is that it has a built in LED flashlight, which is very nice to have if you can't get to your phone or if you phone has a terrible flashlight. I would definitely recommend this battery bank to anyone looking to carry around some extra power for their devices. I know I will continue using this, and it is a great gift for Christmas.
