a step down transformer lets say 2:1 requires 1/2 the wattage, correct? For every watt it uses it provides 2 watts, excluding of course whats lost in the windings. I have a 220 to 110 transformer. The output says "110v", that's all. The input side says "220v "VDE" step down transformer max 300 watts". Now if the max it can safely use is 300, then the 110v side could pull 600 watts safely, right?"
