We had a power outage Friday, Nov. 6, of about 1.5 hours. I backed the NHW11 to the car port. Started it up and turned on the inverter and ran an extension cable into the house.
We ran the TV and a lamp. Then I took my wife's Prius to get dinner. I got home just in time for the power to come back on:
Start: 52.4 MPG, 27 miles, 0.515 gallons
End: 41.2 MPG, 27 miles, 0.655 gallons
0.14 gallons for 1.5 hours of power
When I came back home, the utility company truck was on the street and as I gave my wife her dinner, the lights came back on.
