Hi. Here the power output varies from 1kW to 1.8kW from one model to
another. Also how well pan and ring contact makes a difference. So
yes, its fair enough.

Long ago, cooking rings were often a bare coil of live heating wire
with an open grid over the top. And they were generally rated at 500w.
It took 20 minutes to boil, lemme guess, 1 to 2 pints anyway. And if
it boiled over your cooking was all over the live element, connecting
it to the metal case and thus to the pan. Nice. They're still common
in Japan, despite being none too safe.
