The iZAP was originally designed for users of Apple’s iPod, but now that the iPhone is on the market the iZAP has found a new use.

"The iZAP battery was a life-saver during my business trip to China last week," said iPhone owner Steve Schneider, Chief Executive Officer for ZAP. "Frankly, if an iPod runs out of power, losing your music and video is not as critical to your business trip as the iPhone. You lose your cell phone access, text messages, Internet and email access, time zone clock, business notes, scheduling software, driving maps, calculator and all the other news and information for which the iPhone was designed."

Schneider says that during his testing with his iPhone that you could get about triple the battery life from your iPhone when using the iZAP. No additional cables or adapters are needed to adapt the iZAP to the iPhone.

The iZAP is a 2100mAh battery with a charge time of 5 hours and a 5.0V output voltage. Charging is done via the USB port on your computer. The iZAP also comes with a belt clip. The MSRP for the device is $79.00. Via ZAP World
