It's great for rural folks or others with power issues. For a few thousand bucks, you have a backup generator in your garage.

The only question is range when those rural folks go to the big city (if less than an hour they do this once a week because groceries in the suburbs of a big city are so much cheaper. If farther than that they still go once a month because of things they can't get. Though I don't know anyone who lives so far out that they can't get to a city and back in a long day.

Otherwise rural folks often have something to fix on the other side of their property that needs tools. Cordless tools do a lot but sometimes are not enough.
