Powerstick gives more power to USB devices

Considering that most devices require a usb drive just to get power to them, you would think that someone would simply invent a USB device that holds power. In other words, why use a USB drive to power a battery when a battery can have a USB drive.
Okay, that was a little confusing, but this is the basic concept behind the Powerstick. This device can fully recharge in just 90 minutes, and can (supposedly) double the battery time of any mobile device. It even has 9 different connectors for all kinds of cell phones, the iPhone, and iPod.
The Powerstick is available on the Powerstick site (of course) for $69.95.
