I never got the refrigerator thing as a modern refrigerator does not "run" very often, but it works.
My problem was moving the fridge (out/in) in a narrow galley kitchen.
I've also successfully used vacuum cleaners and power tools in the past (with the aid of an adaptor), but now my vintage heavy duty Kirby vac's have been replaced with lightweight Dyson's, and I can't think of the last time I used a power tool (outside of a Dremel or a food processor).
Maybe a space heater set to a low setting (< 750 watts)?
