My car charger can boil water really fast [video]

Great video, but coincidentally two weeks too late for me:

I never knew about the boil auto-shut-off mechanism and the overheat/"boil-dry" protection circuit being two different things in some kettles. In those, pouring out the entire water before the auto-off had a chance to kick in can cause a situation where the kettle stays on (due to not enough steam being present to trip it), but the boil-dry protection circuit continuously engages and disengages until somebody notices or the thing self-destroys – ours did the latter.

Now we have one with a switch at the bottom, and I'm hoping that due to that construction, the boil-dry protection will also disengage the switch if needed. (It also helps that the switch automatically disengages when lifting the kettle off its base.)

It is always fascinating to see unforeseen failure modes created by automation.

I have a kettle with 5°-settable temperature targets that has transformed my tea drinking.

It also has a function to hold temperature for up to 30 minutes, and because it has actual logic going on inside, when you lift it off the base it knows this and won't turn back on when you put it back.

I have an electric water boiler like that also. I have to be very mindful to press a button to turn it off if i return it empty to the induction plate/holder otherwise it starts clicking and beeping and freaking out.
