Greetings, I found a product today that some of you may be interested in. It's a portable power pack that utilizes USB to supply power to any device that can be charged from a USB port. The device is from Lenmar and is called the PPU2100B. This device is approximately the same size as the iPod Touch. It is slightly thicker but just a tad shorter than the Touch. It has a mini-USB and a regular USB port along with a power switch and dual-color LED to indicate charge state. The company claims that you can get approximately 5 charges from this power pack each one lasting about 10 hours. Naturally this will depend on what you are charging and how you use the device after it is charged. It comes with tips for iPod, PSP and mini-USB devices along with a 3 ft cable with a USB connector on one end and a barrel connector on the other end for the tips. They apparently have another version of this that comes with the wall-wart that you can plug a usb cable into. I bought mine at a local Radio Shack for $39. Seems like the perfect solution for long flights where charging power is not easily accessible.
