Ours is a Smeg model. The two large rings are 2.3kW, with a outer booster ring to 3kW. The problem is if I'm just boiling water for my tea with a saucepan, only the inner ring is triggered. I can put a large pan on there and get 3kW to match the 3kW kettle, but then I've got to warm a large metal pan too, whereas the kettle has very little thermal mass and is lightweight and easy to fill too.
A properly sized tea kettle would solve that but since you already have the electric kettle there’s no sense in buying a new stovetop vessel until the electric kettle burns itself up.
US induction cooktops/stoves are almost always 240V, unless you get a little countertop burner.

As am I. The first time I put a small pot of water on my induction cooktop and turned it on maximum power, I laughed out loud. If I'm only doing enough for a cup of coffee or tea, it starts boiling so fast you don't want to step away.
