The latest iPhone battery pack is another from Mophie, this time in the form of an iPhone 3G case, the Mophie Juice pack Air.
The Mophie Juice Pack Air is a case for the 3G iPhone with a built in battery pack, and from the look of the photos it certainly looks a lot slimmer than the current Mophie Juice Pack.
The Mophie Juice Pack air will give you up to 270 hours of standby time, 4.5 hours of talk time on 3G or 9 hours on 2G, internet usage comes in a 4.5 hours on 3G and 5.4 hours in WiFi.
There is also up to 20 hours of audio playback and 6 hours of video playback, whilst these specifications are less than the current Mophie Juice Pack, it is a lot slimmer and more like an iPhone case rather than an add on battery extender.
The Mophie Juice Pack Air is available to pre-order for $79.95 from Mophie.
