My car charger can boil water really fast [video]

He mentions induction 'hot plates' towards the end, and says that they're limited to the same 1800W and 120V as kettles, but there are "commercial" portable induction stoves that are 220V and can go up to 3500 and 5000W; e.g.:

Just need a NEMA 6 plug (GFCI/AFCI per code as well probably):

In the US. In the UK 2200W induction plates are readily available with a standard plug for ~£40, or if you spend a little more you can go to 3kW - [0] which is about the limit of most domestic circuits but is hotter than most gas hobs.

If you _really_ want more than that you can go a little mental and use one with an integrated battery which can push out 10 kW [1]

This begs the question, and I've genuinely thought this before, of why we don't just strap a battery to a kettle and end this silly debate. If it takes 5 minutes to boil a cup of water in a 1000 watt kettle, that's somewhere around 80Wh... I guess it would be kind of expensive, but couldn't you make a pretty fast kettle with some number of high discharge battery cells?

(Well honestly, I guess the real answer is outside of Internet debates most people probably just don't consider 5 minutes to boil a cup of water to be a problem.)

That seems a terrible waste of batteries to me. A boiling water tap seems like a better idea to me - electric heater with a pressurised insulated vessel that just dispenses from your tap.
