That doesn't make sense (to me): This furnace is running from a 12 Volt
battery. Power is Current multiplied by voltage (In other words P=IE).
So, for something to use 10 amps, it would need to draw 120 Watts. Right?
(120 = 12 * 10).
50 watts at 12 Volts would be around 4 and some amps. (48 = 12 * 4)
And, 400 watts draws about 33.3 amps.
Again, what am I missing about these heaters?
