Powering my house with my C5
I wouldn't try to run a refrigerator off a car inverter unless you get a 5000 watt one, and they are more expensive than a small gas generator. The cheapie inverters that run a few hundred watts would be OK for a few lamps.
As I write this, my 11kw whole house natural gas generator has been running for 24hrs. It looks like another day or two before they get power on, due to Noreaster in NJ. We lived through Sandy in another house with the small Honda unit to run the refrigerator, router and a few lamps, but now I'm in the woods with a well pump that draws a lot of current. My neighbor has a large gasoline powered generator, which works fine but goes through about 10 gallons a day. The problem I had during Sandy even with the small Honda unit was finding gasoline stations open, although it would run for 8 hours on a gallon of gas. Stations are open here now, so not an issue, but still a PITA to have to refill multiple 5 gal cans for a large generator.
