Honestly I kinda already did. Connect 2000W pure sine inverter to terminals on 12v battery in trunk. Plug in extension cord.

It's not terribly sophisticated, but it keeps my pipes from freezing.

Refueling a car is as easy as it gets, though. To refuel anything else, you'd have to put it in a car and take it to the fueling station anyway. This way you just refuel the car the normal way. You can also store whatever gasoline you'd have used in a generator at home too, but the Prius' 10.9 gallon tank holds a lot more than your average portable generator and runs a good, long while.
