This leather case protects and recharges any iPhone 3G/3GS or iPod Touch, providing up to 3 1/2 hours of additional talk time. Simply connect an iPhone or a second or third generation iPod Touch to the dock inside the case and its integrated Lithium-ion polymer battery immediately begins to recharge the phone. The durable leather 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 and iPod Touch up to 1 1/2 times before the case itself needs to be recharged. It comes with a USB cable for recharging via your iPhone's or iPod Touch's AC adapter, or with a computer. Provides up to 36 hours of audio playback or seven hours of video viewing. 5 1/4" H x 2 1/2" W x 1" D. (4 1/3 oz.)
