This is one of the better power banks I have found after doing a bunch of research. This power bank features 10400mAh battery capacity and can be used to charge your portable devices on the go. It comes in handy because everyone knows bluetooth and apps that use more processing power can eat up your battery’s charge pretty quick.

$ 17.56 and free shipping, this includes the power bank and a microusb cable.
