Hi all,

A friend and i are planning to do a trip down south and out of the city lights to have a day of photography including camping at night doing timelapses etc..

The problem is.. well, battery life. Is there any way to directly feed power from the car's cigarette lighter port to the camera?
i have a Nikon D5100, yes a very simple camera (saving up for a better one!) does anyone know of such adapter for doing this?
i know there are AC adapters but don't think there will be any power supply as such over there..

Are there alternatives? (need something cheap) perhaps getting an external battery and hooking it up to there?

I'm interested in finding some ways to make this possible and not only take 400 shots before it dies

Any recommendations would be gladly accepted!

Thanks

Andrew
