mStation | mophie announces juice pack air, the world’s thinnest apple-certified external battery for iPhone 3G. The rechargeable 1200 mAH lithium polymer battery housed in an ultra-thin case virtually doubles the amount of time you have to rock, talk, surf, and send.

Juice pack air features an innovative “standby mode” that allows users to control when they want to take advantage of additional battery support versus simply using it as a protective case.
The integrated 4 LED charge status indicates how much juice is remaining in the external battery. Unique pass-through design allows users to simultaneously charge their juice pack air and sync their iPhone 3G with iTunes with the included USB cable. Juice pack air will be available world-wide this spring at Apple stores for $79.95 in Black, White, and Purple.
