Apple’s new iPhone didn’t get the aesthetic overhaul some people were looking for, which is a big win for third party manufacturers. Forget clearance prices; accessories like the Juice Pack Air carry over seamlessly, and in the case of Mophie’s gadget, actually improve.

According to Mophie, the Juice Pack Air, a combination protective case and battery life extender, nearly doubles the battery life of an iPhone 3GS. The company cites the following specs for their battery:

* Standby Time: Up to 270 hours
* Talk Time: Up to 4.5 hours (3G) Up to 10 hours (2G)
* Internet Use: Up to 4.5 hours (3G) Up to 8 Hours (Wi-Fi)
* Audio Playback: Up to 27 hours
* Video Playback: Up to 9 hours

For $80 the Juice Pack Air is tough to beat. You can have one in purple, black, or white.
