An automatic kettle brings water to a boil and cuts power by itself, so you can fill it, press one switch, and walk away until it clicks off.
- Capacity and wattage together decide speed: a 1.7 liter body at 1500W suits a household, while 1.0 liter heats faster for one or two cups.
- Look for auto shut-off plus boil-dry protection, and a lid that opens wide enough to clean inside.
- Check whether the model offers set temperatures or a keep-warm hold, which matters for green tea and pour-over coffee.
Compare cord length, base rotation, and water window placement before you choose.
