A kettle, sometimes called a tea kettle or teakettle, is a type of pot, specialized for boiling water, with a lid, spout, and handle, or a small kitchen appliance of similar shape that functions in a self-contained manner. Kettles can be heated either by placing on a stove, or by their own internal electric heating element in the appliance versions.The heating element is typically fully enclosed, with a power rating of 2–3 kW. This means that the current draw for an electric kettle is upwards 10 A, which is a sizeable proportion of the current available for a typical home: the main fuse of most homes varies between 20 and 100 A. For this reason electric kettles, while available, are much less popular in countries with 110 V mains electricity, where electric sockets are often current limited to providing around 1.5 kWs.
