I have a car charger piece that takes a USB cable and plugs into the cigarette lighter of a car. It was for a Palm Pre but technically any USB chord can plug into it. How do I know that it's safe and provides enough (but not too much) power if I plug my Nexus S into it?
I think what it says is:
INPUT 10-26 VDC
OUTPUT 5.0 VDC
