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...

Loss will be 10% to 15% so 50 watt load is ~55 watts out of the battery.
55w / 12.4v = about 4.5 amp battery load.
55w / 12.4v = about 4.5 amp battery load.
