I have to admit the 240v (2kw) kettles are impressive. Evidently the Brits and their offspring down under are pretty impatient when it comes to their tea. The delta on a liter of water is over 50 degrees a minute. You can boil it in about 2 and a half minutes from room temp water. It goes a lot faster if you only make a cup or two at a time. We were in a hotel room and I cooked hot dogs in an empty beer can by filling it with boiling water a couple times.
