I have never used one, but have searched for info.This is what I found,buyer beware,it's all hearsay.The Power House is supposedly a Chinese knock off of the Honda units and Harbor Freight sells,or sold, the same thing, just re-branded to their brand.I have checked out the PH next to the Honda.The PH was a little lighter.Just enough to be able to feel it.I don't know if the weight difference means the PH is lacking quality, because of inferior metals, or if they had to change the design a little to keep from getting sued by Honda.That is all I can really say for them.I don't know about noise levels,reliability,or longevity.I plan to try one.
Chinese engines is something I can give some info on.When I buy them,first thing I do is drain the crankcase of oil and refill with kerosene.Shake the engine around for a few minutes,being sure to get it up all the sides.I let the engine sit for about a half hour at an angle with the drain port down.Then I drain off the kerosene into a pan.I do this as many times as needed, until I can't see debris coming out.Then I refill with good conventional oil,usually 30w Castrol GTX.Then I run the engine at half speed for a half hour,drain the oil,and check for debris.I do this until I can't find debris.The silver stripes in oil will be normal as the engine breaks in and should get better over time.The debris I find is casting sand,cast flashing,and machining shavings.I have went as far as disassembling some Grey Hound (Harbor Freight) engines and cleaning them out.I would consider buying the extended warranty with either brand.I have had good luck with no question asked exchanges when those motors crapped out.I see no reason why it would be any different for the generators.
