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.)
