Mophie Juice Pack Air

Most users of the iPhone 3G and 3GS identify two primary problems with the device—its battery life, and the tendency of its case to pick up scratches, fingerprints, and dings. The Mophie Juice Pack Air solves both of them by integrating an external battery into a hard case. On its face, the Mophie Juice Pack air is a smooth plastic hard case available in black, white, purple, or soft-touch red. It does a good job of protecting an iPhone from the bangs and knocks that are a part of modern life. However, inside the case, Mophie has hidden a 1200 milliamp hour lithium polymer battery. Although its capacity will vary depending on application, third-party tests have born our Mophie's claim that it will double the iPhone's battery life. Excitingly, it does this by adding only a small bit of thickness to the phone, and just twenty percent more weight. The Mophie Juice Park Air can be left connected to the iPhone at all times, since it can pass iTunes synch signals through the Micro-USB port located on its case that is also used for charging. To make it easier for users to gauge the condition of its battery, the back of the Mophie Juice Pack Air features a 4-LED power level indicator. This device is the perfect companion for any iPhone 3 or 3GS, as well as for future iPhone and iPod Touch models to be released.
