Inverter question about 12v draw
At 50 watts of draw at 110v, how much will an inverter draw off house batteries? I know 50 watts at 110v equal about .45 amp. What is the formula for converting it to 12v less the efficiency loss of...

What it takes to run the inverter is a function of how big the inverter is, whether PSW or MSW, and varies with load. By that, I think there is a certain loss even if there is no load, plus there is an inefficiency loss proportional to the load the inverter is serving. I wouldn't doubt that there is also a difference from manufacturer to manufacturer, but I don't know what any of these are, and I don't know how to go about guesstimating the sum of them for an arbitrary and unspecified inverter.
As for the equation, it is volts x amps = volts x amps. (110 volts) x (.45 amps) = (12 volts) x (solve for amps) OR (110 volts) x (.45 amps) / (12 volts) = (solve for amps).
