The RAVPower 26800 External Battery Pack is a 26800mAh 5.5A 3-port power bank. It charges any USB powered device including smart-phones. A great gift for a person who travels or is a camper and needs to be able to charge their device when there isn't any power. We use it even at home, as a way to use a mobile device on the couch or keep it portable even without a power plug. We love ours and use it more than we thought we would.
