Running out of battery power in the middle of playing a video game is about as fun as pizza burn but most of the combination battery pack phone cases either triple the size of an otherwise sexily-slim phone or looks plain ugly. Mophie has found a way to charge and protect smartphones without sacrificing aesthetics. Enter the Juice Pack cases that are available for every popular smartphone out now. Instead of fiddling around with cables and a separate battery pack, Mophie cases stay attached and are activated with the flip of a switch. Best part of all is that there are a number of options to fit any gamer's style.
