I have been using a Mophie Juice Pack for my original iPhone for a long time now. The device gives me much more call time and lets me play games and music longer before the phone is dead. Using the Juice Pack I get roughly twice the run time on my iPhone.

Mophie has announced a new version of the Juice Pack for the iPod touch 2G that promises significantly more run time when used. The touch 2G Juice Pack fits onto the iPod like a case and provides up to 72 more hours of playback for audio and up to 7 hours more for video.

A pass through charger allows the use of the stock charging cord to charge the Juice Pack and the iPod internal battery at the same time. Technology inside the Mophie uses the external battery before switching to the internal iPod battery. The iPod touch 2G Juice Pack retails for $99.99 and is available now on the Apple store.
