I have been using a power pack from APC that is twice as thin and considerably cheaper...I'm at work so don't have the model number, but functions the same way, with a short USB cord used to charge on the go...as a matter of fact, I can fit the phone, attached to the APC, in the front pocket of my shorts, it's that thin...I'd say it probably has the capability to charge the phone 1 1/2 to 2 times, so not quite as much juice as the one above, but certainly a lot cheaper and I believe thinner...
