I am using 800W from HF for like 5 years and for mountain camping prefer to run it, keeping the build-in 3600W inverter propane generator quiet.
Even the muffler is small, with the engine size it does not make much noise.
That thing runs everything in my camper but AC, but camping in the mountains I never need AC.
Great buy for $80.
Harder to start than my electronic Honda, but I've been dealing with small engine since I was 14, so lot of experience.
Keep the fuel valve off when not in use.
