I've used something like this for years at Oshkoah:

Small, fairly light - take a couple and you'll have all the power you

I'm going to be in plane camping at Oshkosh this year, and I'm wondering
how I'm going to keep my camera batteries and iPod charged. I know from
harsh experience that keeping the airplane master on to use a cigarette
lighter adaptor runs down the plane battery pretty damn fast, so that's
not a good idea. Is there such a thing as a battery powered portable
generator?
