This leather case protects and recharges an iPhone, providing up to 13 hours of additional talk time. Simply connect an iPhone to the dock inside the case and its integrated Li-ion battery immediately begins to recharge the phone. The durable leather case protects your device and snaps shut to ensure secure, confident storage. The case is slim enough to stow comfortably in a pocket, and you can turn off the charger at the touch of a button for use as a traditional protective cover. The case can recharge an iPhone up to 2 1/2 times before the case itself needs to be recharged. The case recharges in five hours using a USB cable or an iPhone AC adapter (neither cable is included); works with your existing iPhone cable. Provides up to 40 hours of audio playback, 12 hours of video, and 10 hours of Internet use. 5" H x 2 1/2" W x 1" D. (4 1/3 oz.)
