Yeah thats a strange US only quirk: lack of kettles and 120V power. I have a 3Kw kettle at home. I boils 2l of water in a few minutes. If I add just enough for one hot drink, then it finishes before I have my mug and ingredients ready.
I cannot imagine a home without a kettle, its the first appliance I bought when I moved countries. I also cannot abide by a kettle less than 3Kw anymore either.
