Yeah. Our new five-quid kettle here can do that.

And I really doubt their efficiency claims -- a standard immersed-element electrical kettle is damned near 100% efficient to begin with.

Just tried our reasonably fast boiling flat bottomed kettle. With a single mug of water (which is after all what we should be comparing the Tefal heater to) it boils in about 50 seconds. However with that little water in it takes quite a long time for the boiling sensor to trip so the element is actually on for 65 seconds.

Assuming the element in the Tefal has the same rating as in the kettle, then that would fairly closely match their 65% claim. Though of course with the kettle I actually end up with boiled water.
