This system includes a slim case for the iPhone 4 / 4S as well as an optional modular battery, which has a capacity of 1250 mAh and easily slides onto the back of the phone’s case to charge it. Up to six batteries may be combined. The best bit is that the battery can charge other devices, such as smartphones by other manufacturers thanks to the micro-USB cable included. A universal charging device with a sleek, modern design. It’s about time.
