Inflight USB Power Unit Charges Gadgets from Airline Audio Jacks

The Inflight USB Power Unit pulls power out of your in-seat audio jack and bridges it to a USB connection, allowing you to charge any device that can be charged over USB. I have to admit, I'm a little surprised an audio jack on an airplane would have enough oomph to recharge even small gadgets, but I suppose as long as it's enough power to trip the internal "I'm getting juice" switch, good enough.

The basic model is $35, although they'll sell you ones with custom tips for $10 more. (Just bring your cable from home and get the basic USB model.)

Anyone have one of these who can testify to its effectiveness?
