The juice pack air is a rechargeable external battery concealed inside of a protective form-fitting case for the iPhone 3G and iPhone 3GS. It offers you the full protection of a hard-shell case while providing virtually twice the battery life of the iPhone alone; all in an ultra-thin, light-weight, low-profile design.
