Found this on Ebay. Plugs into cigarette lighter and shows voltage and ambient temperature. Less than 5 bucks shipped. Temperature is in Celcius but I can convert that in my head fairly quick. Love it..164160

It would be nice if the temperature displayed both C and F

There is another very similar one that does display Fahrenheit.
