Yeah, I've got a portable a/c unit that I move into our bedroom when the power goes out.I have a 4800 Watt inverter that does propane or gas. Getting a manual transfer switch in the garage soon, problem is it will only do 110 so can't run heat, air, or dryer. No issues there I got fans and can plug in electric heaters. It's mainly for my mothers oxygen creator which she definitely needs. I can live without the rest.
