Need some extra power time for your Apple iPhone?
The new iPowerRush can add up to 10-15 extra hours of use time, and up to 120 hours of standby time to your handset.
The device is basically a 6 AAA battery pack with a built-in voltage limiter, which connects to the phone and provides additional power. It has one downside though: with a size of 2" x 3.5" x .5" it is pretty large and inconvenient to be carried around.
The price is $29.95.
