So I did a little testing and want to post the results I got (if anyone wants to put it into an easy to read graph that would be great).
So I measured the voltage out of the wall socket at 118v which goes to my 3,000 watt step up voltage converter/transformer.
I can't help think that you're losing efficiency by stepping up the voltage. Transformers aren't very efficient, as quite a bit of power is lost due to heat.
Yes, I agree. I pointed that out in a earlier post.
