It seems like we’ll soon forget about the painstaking of having to worry about your battery draining and not being in the proximity of a charging device.
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.
