The highest rated 115V kettle I’ve come across here is 1500W with the majority on offer being only 1000W – I saw one rated at 750W! Morning tea is a must and time is short at that time of day. One cannot beat 3kW of grunt to raise 2 pints of cold water to boiling point in about a minute.
I own a 500W kettle. You fill it up in the evening and plug it in. In the morning it has hopefully reached boiling
(I barely dare to use it. It is all metal and make strange noises as it heats up. My dad bought it when he went to high school a long time ago)
