The Dual Device Backup Battery

Was $79.95 NOW $49.95

This is the pocket-sized battery pack that simultaneously extends the running time of two electronic devices. The rechargeable 6,000mAh cell stores enough power (accessed via its dual USB ports) to charge two tablets or two smartphones to full charge twice before needing a charge itself. The battery automatically detects the type of device to which it is connected and adjusts the amount of power delivered accordingly. About the size of a pack of gum, the battery has built-in surge protection that prevents damage to devices while they are charging. Recharges via USB with included cable or via AC with your device’s AC adapter. 1" H x 1 3/4" W x 3 1/2" L. (5 oz.)
