mStation|mophie is shipping the US$99.95 juice pack iPhone 3G
(http://www.mophie.com/products/juice-pack-iphone-3g), for the iPhone
3G. It offers an extended battery and a case all in one with an
ergonomically designed, soft-touch, non-slip rubberized finish.

An included USB cable enables you to simultaneously charge and sync
your iPhone to iTunes without having to remove it from the juice pack
3G. Intelligent power distribution instructs the iPhone to always
drain out the juice pack first. When you’re done with the juice pack
3G, detach and you still have a fully charged phone.

The juice pack’s integrated LED status indicator tells you exactly
how much juice is left and also displays how much time remains during
the charging process. According to the folks at mStation/mophie, a
fully charged Juice Pack 3G give users more than twice the power of
the iPhone 3G’s standard battery life.
