Terry is correct. I was implying that many chinese things don't achieve their "rated" outputs. Cheaper electronic and electrical things from china are notorious for this. So the joke was if you actually tried to pull 3.5 kW from that (American kW, if you will) it would fail and provide low voltage, and destroy your things. They are *supposed* to put out 220/110V 60hz AC.
FWIW I have an 8750 HF Generator. The engine is a direct copy of a Honda (by direct, I mean I can put Honda parts on it), but when hooked to a load bank and spun really pushed, I get about 7.5kW before it just gives up, and only about 7.3 kW before the voltage starts wandering. I'm fine with it, because I knew going into it that it the rating was more of a guideline than a hard rule.
Same thing with a couple VFD's I have. I buy about 1-2hp more drive than the motor I plan to attach to it, and it works fine. Try to run a 3hp motor on a 3hp Chinese VFD, and you should have a fire extinguisher handy. Even having to spec up the stuff, Chinese components are cheaper than "smaller" US, European, or Japanese ones. Slave labor will do that for a business, I guess.
I recommend HF generators for occasional use, because they are cheap, and work well if you realize you are buying ~80% of the generator on the label. Except the two stroke one. That things a POS.
