Yeah it is
We decided to get one last winter when rhw power kept going out
I'd have to check the exact numbers but it is somewhere in the 5000 watt range
Perhaps not strong enough to run the entire house, but I got my breakers divided in essential and non essential and it did just fine last nite
My freezer stayed on, the sump pumps worked and we had light in the rooms we were in, so all is well
If I ever strike it rich I may have one of the general units installed, that run on natural gas and fire up automatically, but for now, this worked just fine
