Lots of folks have two Honda 2000i because of ease of handling
(around 50 lbs each) and very low noise.
One 2000w could put a strain on the AC comprssor and even cause damage that's why you don't want the start up load of the AC coming on and off. Some take the chance and run with one.
I have a 3500w with the 30amp 120AC output also 220AC should I need 220. However; it's heavy and not as flexable as the smaller Honda 2000i units.
Then again I paid $650 for mine with a 6hp Honda engine while the 2000i run $800 plus each.
