Don't know if this helps.
Ohm's law... V * A= W
Volts times amps equals watts. Or watts divided by amps = volts, or watts divided by volts = amps
Use this to figure fuse size minimum for things like lights. Two 55w lights, 110 watts total at 12V =9.2 amps.
So in theory a 110v inverter putting out 75W should put out.7A But it would take 6.25A @ 12 vo;ts.
Confusing myself, time for my last beer for a while. back on the pager for a week starting in the AM
