One of my generators running. PepBoys 1200w Peak (850w rated). It’s still compared to alternative incomparable units as well as essentially has a great sized muffler. we wouldn’t run it overnight in a city area but, it’s still sufficient for day use. It’s has a dual cadence 2hp gasoline engine which requires a 50:1 oil premix. And, it’s utterly small. Compare it to a emporium flare in a video for size.
