Fusion Audio Technologies has introduced the iPowerRush, a battery charge extender for the iPhone and iPod. It costs $29.95.
The iPowerRush is powered by six replaceable AAA batteries (not included) and features a 30-pin dock connector, making it compatible with iPhones and all iPods that use the dock connector interface. A power switch and a push-button power indicator are also integrated into the unit, and a limiting circuit prevents it from overcharging the iPod or iPhone.
The manufacturer suggests that the iPowerRush can extend the iPhone's talk time by up to four hours, three more hours of Internet use, 3.5 additional hours of video use, 14 hours of audio use, or 120 additional hours of standby time.
