I actually have 2. a 650w honda that only weighs 40 lbs and runs for hours on a liter of fuel. Its enough to run all of the essentials on the tank and is super quiet when running just outside the sliding glass door. I also have a 2150w crappy tire model that really is just a rebadged mitsubishi
Not so quiet or frugal but will run the whole tank + other stuff. I really bought this one for running stuff in my RV tho.
