Keep your iPhone 4/4s protected and charged with the mophie juice pack air Battery Case in black. This case features a built-in battery and protects your device's back panel and sides. The lithium-polymer battery extends your device's battery life by up to 105%, so you can stay connected for longer. Internal rubber bumpers absorb shock, and a raised front bezel lifts your screen away from dirt and dust when placed face down.
The juice pack has LED indicators on the outside so you always know how much power it has left, and an on/off switch gives you control over when the case's battery kicks in. It also features digital power management and pass-through charging and syncing, so you can safely charge your phone's internal battery and transfer data via the included micro-USB cable without removing your juice pack.
