transistor

 

I see pictures but what is the question???

 

I have two of the smaller inverters sort of similar to that, one rated 400 watts and one rated 800 watts. I checked both with a100 watt light fora load, each required a bit more than ten amps to provide 120 volts to the 100 watt light. so 120 watts in 100 watts out. not by any means the best efficiency, but adequate for running a power tool from an auto battery if I can have the engine run to keep the charge up.
