Mophie ships $80 juice pack air for iPhone 4
As speculated last week, Mophie has released a Juice Pack Air case that doubles as an auxiliary battery for the iPhone 4. The seventh in the line, the pack is made of soft-touch plastic and can nearly double the battery life of the iPhone 4. The pack is said to provide up to six hours of extra talk time on 3G networks and up to 12 hours on 2G, with up to 36 hours of added music or nine hours of video.
The 1,500mAh lithium polymer battery has overcharge, short circuit and temperature protection. A four-light battery indicator LED is built in, and a pass-though USB connection is provided, letting users sync the device with iTunes without the need to remove the case.
The juice pack air is now shipping for $80.
