Nice idea, lots of energy.
But instead of using an inverter to go from 12v to 120v AC and thenusing a transformer to go back to 5v DC, why not get a 5V regulator,whack a heatsink on it and then wire the output to a couple of USB portsthen you can plug your iPod and phone into the USB port. Would be alotmore efficient and a voltage regulator is cheaper than an inverter.

yes and i explained that in the instructable, while that would be moreefficient to not step it up to step it back down, it is just an exampleof how it can be used
