Capacity: 1800mAh
Refill+ is our winter collection series designed for iPhone 4/4S. It is a slim iPhone case with a detachable battery pack. Unlike other backup battery products, it is portable and of much higher capacity.
Refill+ is made for iPhone certified. Like refilling a hot coffee in the cold winter, Refill+ helps to refill energy for your iPhone battery. We provide six theme colors: black coffee, vanilla, green tea, chocolate, sakura tea and morning glory.
By attaching the battery pack to the ultra-slim protective case, Refill+ can be easily connected to iPhone charging port, and provide at least 0.5~2 times backup power for your iPhone 4 battery.
