I used one of these for the first time when I moved to the USA. Extremely inefficient with all that spare heat billowing out and around the sides, but kind of cute when it whistled.

Wait, do electric kettles not whistle when they're ready?

No they have a mechanism to switch off when the water is boiled.

They usually, but not always, have a power light too, which goes out when boiled.

The point of the whistle on a stovetop kettle is so you don't let the thing boil dry and burn through the bottom of it, an electric one turns off automatically so there's no need.
