Griffin Technologies makes a great line of iPod products.

There is an iPod mini iTrip available here.

Well you actually dont need a power inverter to charge an iPod. I think there are many 12V adaptors you could use that have fuses on them in case you're wondering about shorts and stuff.

Here's one from Griffin.

I've never tried the Griffin one before. I personally just use the one made by Belkin.
