More iPhone juice, less bulk

摘要

The scoop: Juice Pack Air, by Mophie, about $80. What it is: An update to the original MophiernJuice, the Air is a rechargeable external battery case for iPhone 3G users. Not only will the Air give you extra battery juice when you need rnit, but the hard plastic case provides additional protection for your iPhone 3G. Mophie says the battery provides users with an additional 270 hours of standby time, up to 4.5 extra hours on 3G (9 hours on 2G), and up to 4.5 hours of data time on 3G (extra 5.4 hours on Wi-Fi). For multimedia use, the Air provides as much as 20 hours of additional audio playback time, and as many as six extra hours of video time. A button on the back of the Air and four LEDs give you quick notification on how much battery power is left on the device. Cases come in three colors: white, black or purple (interesting color choice!).
