How about what you put under your stew? I'm looking into buying a portable hotplate to use during power outages when I have access to a powerline run from the next door neighbor's generator behind their home. It seems the higher-priced induction burners are less likely to overheat the base of the unit, and appear to be stable. Duxtop is a brand I'm seeing. Least expensive are the coil burners with a knob, Black and Decker, etc. There are plenty of other appliances in the kitchen to plug into the power strip such as the electric kettle or the microwave. But to actually cook something when I can't use the regular electric stovetop, that's what I'm investigating.
