Query: Does not charge, only runs iPod

I bought this to use to charge my video iPod while at a cabin with no electricity. Turns out, it will run an iPod while you listen to it, but does not just charge an iPod. This is problematic when using an iTrip to run the sound through a radio, since they both plug into the same slot. I did get it to slowly charge a friends Nano though...
