I don't know about others. But I just wanted to throw in that my magnet mount has a internal temp control(250F if I remember correctly). So I'm guessing that style probably wouldn't work with 12V.
If you just do the math of Volts x amps = watts.
200watts at 12V = 16.666amps
800watts at 12v = 66.666amps
I believe that's per hour correct? I'm a little rusty with the power calculations.
