Another day another iPhone 4 battery case. Pinned as the slimmest battery case for iPhone 4, the Snap Battery Case features a 900 mAh battery and durable hardshell construction to protect the handset. On the back are a set of LED lights to convey battery life, while a switch controls the power. 900 mAh won’t provide a full charge to your iPhone, but should add an additional 40% of juice, at least according to InCase, which sounds conservative since that’s more than half the size of the iPhone 4′s battery.
You can snag the Snap Battery Case directly from InCase starting today for $59.95. For a little more bang for your buck, they’re including a USB to 30-pin cable – usually these cases are mini USB to USB.
