For those who have made the mistake of packing your phone and its charger separately when traveling, the Portable Backup Battery will resolve those travel headaches. Designed and produced by Photive, the $28 device works for cell phones, smartphones, eBooks, PDSs, and most other USB-powered devices.
Packing 2600mAh of battery power with a 1A USB output, the Portable Backup Battery is especially useful for those traveling long distances without having a plug or outlet immediately available. The device itself is shaped like an ordinary lithium battery holder, and is small enough to be carried together with your phone. It is charged by a smaller, input USB port, while the external USB port is compatible with most devices.
