Card Type Emergency Charger – a handy external battery

USBFever has recently introduced an external battery that is almost as thin as a credit card.

Card Type Emergency Charger is only 7mm thick, it has 400 mAh and can be used to synchronize the iDevice with a computer.

The battery can charge an iPhone at approximately 25% of its capacity, but that’s enough to solve urgent problems.

Card Type Emergency Charger from USBFever can be purchased here for $ 12 and it works with almost any iDevice.
