Aside from the on-screen keyboard of my iPhone the thing I dislike most is the battery life. If I watch YouTube videos for an hour or so the battery is nearly dead. If you have the same problem with your iPhone or want to get more music and video playback from your iPod, i.Sound has come to the rescue.

i.Sound has announced a new 2-in-1 Charger & Battery Back Up solution that is compatible with the first generation iPhone, the coming iPhone 3G and all iPod’s using the 30-pin connector. The battery looks pretty cool and features LEDs on the front to show at a glance how much battery life is remaining.

According to i.Sound the battery back up is good for an additional 30 hours of music, 6 hours of video and 3 hours of voice calls. The battery will also act as a charger when connected to your iPhone and charges the iPod/iPhone and its own internal battery at the same time. The device ships with a USB AC adapter and a retractable USB charging cable. The price for the i.Sound Battery Back Up is $49.99 and it is available now.
