Then you are basically using your car as a generator.

That is true.

Anyone can do that.

That is also true, but the Prius has the advantage of only running the
gasoline engine as required. Most other vehicles will run the engine
continuously at idle. ... That's not a show stopper, but it wastes
energy. A properly sized generator is more efficient than either one,
but I already have the Prius and don't need power backup very often.

Thanks to you and all the others who provided input.
