Does nikon have a car charger for their cameras?

I'm looking for a car charger for my Nikon D60, any help out there

No, nor do any other dSLR makers. Not yet anyway.

It takes about 3 hours to fully charge a camera battery and most of us are not on the road that long and of course when the car is not running, the 12 v access point in your car is not hot.

When I travel in a motor home, I carry a generic 12 v charging device and IF I have to use it, I set a timer so I do NOT over heat or overcharge the batteries when using it. Usually using the AC outlet on the coach when hooked up at a RV park is the best way to go
