powerless travel charger

[dan-htc-touch]

hey all, I stopped in at wal-mart today looking for nothing in particular, and I came across a travel charger for usb device that runs off one AA battery. I am not sure how much of a charge one would get out of one battery, but it was only $10 so I am not too worried if it turns out to be not all that great. Just thought I would let you all know it existed, for those who might have been planing to build the minty charger seen on an online tutorial.

I'm considering trying this:

OPTI-UPS SCS001 Solar Panel Charger for Mobil PHONES, MP3/MP4,CD PLAYER, CAMERA, PDA, W/FLASHLIGHT $51.60 (http://www.ncix.com/products/index.php?sku=22984&vpn=SCS001&manufacture=OPTI%2DUPS)

Though it's 1100mAh Lithium Battery is less than what most of our phones have, at least it will provide more juice than an AA along and provides a solar panel to slowy recharge.
