Mophie Juice Pack Air for Verizon

The Mophie Juice Pack Air for Verizon is a rechargeable external battery case for the iPhone 4. With its 1500mAh rechargeable lithium polymer battery, the Juice Pack Air for Verizon just about doubles the battery life of your iPhone 4.

This battery is equipped with five hundred milliamp fast charge technology. Besides contributing to battery life, this case also offers protection from bangs, bumps and drops, thanks to its rubberized finish.
