"The thing is, how many amps you can pull without melting your wiring depends on how heavy the wire is. This limits US appliances to 1.8 kw. "
1875 watts, actually.
Which is quite enough for a kettle, unless you are trying to boil the water in roughly the time it takes to put water in the kettle. Having 30 seconds more to contemplate tea type choices is not always a bad thing.
