Induction cooker doesn't work on grid AC frequency (50-60Hz), it converts grid AC to DC then converts it to high frequency (24 kHz), so possibly induction cooker can be modified to run straight from DC power

so possibly induction cooker can be modified to run straight from DC power

I ass-u-me that's how the induction stoves in modern RVs/caravans work, rather than wasting house battery inverting DC only to convert it to something else.

EDIT: well, I guess that's why "assume" is hyphenated. According to the company that makes stoves for Winnebago, from their manual: "1. Plug into standard 110 outlet."

That's because running #0 copper gauge is expensive. You use the inverter to go from 24 (or 12)V to 110 or 240, run your standard wiring and then wherever you need power you step back down again. It's far more cost effective that way, and much safer as well because the connections do not carry nearly as much current. Even a small resistance will cause a lot of heat at currents in the 10's or even 100's of amps.

most RV's don't have all that hefty of house battery capacity (my parent's house battery is 2 deep cycle lead acid batteries). Heating things takes a lot of power, probably run those batteries down before you got much more than a single kettle of water hot. Anything that's going to use an electric stove is most likely going to have a generator.

Or gets plugged into an outlet at a campground.
