I am certainly not recommending this machine. But I am commenting on the fact that it uses a toroid (donut shape) transformer which is very much more efficient than a standard "E" transformer.
The plus minus eight percent regulation is realistic. The fact that it offers 120 / 240 operation means it can be connected to 240 and yield 120 or connected solely to 120vac.
Might be the way to tame psycho crude generator voltage output.
China is building this stuff for third world countries. Pretty tough to beat the price. Toroid transformers themselves are not cheap.
And it is obvious this critter is not weather resistant.
My Mega Sola ferro resonant line regulator is like housing a 6'5" 15 year old. Tips the refrigerator forward and everything slides into an insatiable mouth. At best it is around 83% efficient but this biggie is it's almost 180 watt burden just sitting there humming the theme song to "Are You Bankrupt Tonight?"
