Are we really talking about the same thing? Did your's get hot, heating the pot or pan that way, OR did it stay cold, and heat only the pot/pan inductively via magical magnetics!1!!, which means a piece of paper would not even begin to burn if you'd put it between pot and 'cooking field' when for instance boiling water, making scrambled eggs, or something like that?

Inductive heat, not radiative. Fairly high frequency coil coupled to the pan, pot, etc.

  Then I can't understand why it would be slow. Because even the cheapest ones limited to 1500 Watt at 230 Volt heat water in about 2 minutes to boiling bubbles, 100°C. And then you can play with it, some allow steps of 10°C, some others only 20°C. Response is instant, trailing maybe 3 seconds max. Maybe you had the wrong pots? Or, as I have written initially...inferior electrics :-) edit: Or the thing was partially broken/defective.

    Maybe with a cup or two of water, not a whole pot.

    1500W for 120s gives you 180kJ. Energy required to heat water by one degree 4.19 kJ/kg/K Then, heating by 80K (20C to 100C) requires 335.2 kJ/kg. Thus, at most, you were able to heat 180kJ/335.2kJ/kg = 0.53kg~0.53liters. A large tea mug. Hardly the 'large pot' that was mentioned above.

      Sorry, I've been unclear there. Mine are 2500W. Those I have direct and continuous experience with. But I've seen the 1500W and 2000w in action, too. I could also switch the display to Watts and use that as unit, but didn't do that, except for testing when it was new. Degrees C is the most practical for me. Anyways. They aren't that slow. That would be unacceptable for the people where I've seen them. Btw. for tea and coffee I use a dedicated boiler with about 500ml because my mug is 390ml :-) However, when new, I tested with exactly one Liter.

        You were very clear: “ 1500 Watt at 230 Volt heat water in about 2 minutes to boiling bubbles, 100°C” when replying to a comment about a large pot of water. That’s simply not true, courtesy of thermodynamics.

        Then I've been tiiiiireeeed, or whatever. Maybe even tired of reading the same shit over and over again. Of https://xkcd.com/386/ https://xkcd.com/386/ and so on. In general that inductive heating stuff is good, and has excellent handling. If it doesn't it's either underpowered, defective, or used with the wrong pots. BASTA!
