FWIW the portable ones are great when you live in cheap apartments with shitty stoves. One of the few good investments I made in college...

I have a portable induction for the vehicle, if I am camping in an emergancy it works great to boil water extremely fast.

Though, as a student, if I lived in an apartment with a gas hob I don't know if I would have bought a portable induction unit to replace it.

How did you power it from the vehicle? Not from the 12V outlet, right? Don't those stoves draw hundreds of watts?
