As a sidenote: during the 80s I was traveling a LOT. I used to pack a small electric fondue pot (aluminum) to take with me. Although it would take awhile for anything to actually come to a boil, I could cook a variety of things in that pot.
People would stop by my room often to see what I'd have cooking. Armed with my fondue pot and an electric timer, I would always have something of a hot meal ready for me when I got back from a flight mission.
