Hi Les,

If the the current carried through a USB connection doesn't fry the iPod
Having too much "Current" can never fry anything. Too much voltage can. The Current rating on a power supply is the maximum amount of current that the power supply can provide at a certain voltage. The device using the power supply determines how much current will be attempted to be drawn from the power supply. If the device tries to draw more current than the power supply can provide, then, depending upon the regulation ability of the supply, the voltage will drop and the supply can overheat or malfunction.
As long as the power supply is rated at the corrent voltage and has, as a minimum, the required current rating, then the power supply can be used. Of course, polarity is very important. Make sure you don't get it reversed.
The nice thing about devices being powered through the USB connector, is that there is no way to get the polarity wrong. And any of the USB power devices can be used. I use the Griffen power cube with the USB cable to power my Ipod, Dell Axim, and a MIO GPS unit. I also have a Belkin USB lighter plug adapter that lets every thing be used in the car.
