This mobile power hub is smaller than a deck of cards yet recharges and provides instant auxiliary power to an iPod, BlackBerry, digital camera, or cell phone, eliminating the need to carry multiple chargers and power cords or locate an AC outlet when traveling. The charger has a USB port and a pivoting USB arm that plugs directly into a device, ensuring compatibility with most electronics, including the PlayStation Portable video game system, Game Boy Micro, Motorola phones like the Razr SLVR, and Rokr, and more. Multiple devices can be powered simultaneously, or the unit can recharge an iPod nano seven times or a BlackBerry three times on a single charge. With built-in protection against power and temperature surges and high-input voltages. The unit's built-in lithium-ion battery recharges in three hours via the included AC or DC adapters, or in six hours using the included USB adapter. 1" H x 2 2/3" W x 3 1/4" L. (5 oz.)
