USB CELL

I found these via StumbleUpon and was a little intrigued. Seems like they would be quite convenient for some people.
 
Oh, and it looks like they also sell a 9v version, among other sizes. Hmmmm... so I could charge a 9v via my car stereo or laptop on the way to a gig, pop her in and rock on! Assuming, of course, that they actually hold a decent charge.
