The Samsung Galaxy S III juice pack case virtually doubles the Galaxy"s battery time by housing a 2300 mAh battery. It’s one of the slimmest S III battery cases on the market, yet the juice pack’s comfortable, ergonomic design and tough, light-weight materials fully protect your phone. There’s no need to give up any features or functions, because the juice pack lets you easily access all of the Galaxy’s controls and keeps your ports, buttons, speakers, camera and flash free from obstruction. Keep sharing through touch, since our case won’t interfere with your phone’s NFC or S Beam capability.
