Mophie has just outed the Juice Pack Plus external battery case for the iPhone 4. The 2,000mAh battery more than doubles the iPhone 4′s life and is the largest-capacity and the first to work with both GSM and CDMA iPhone 4s. It’s made of durable rubber and don’t worry about it bulking up your iPhone too much, it adds just 1mm to the thickness of Mophie’s Juice Pack Air case.
To celebrate the launch, a special edition of the case in purple is being released. Only 3,000 will be made. Other colors available include all black or black with cyan, magenta or yellow banding.
All feature a four-light LED battery status indicator, a standby/charging switch and a design that enhances the sound of the iPhone 4.
