Interesting what power do microwaves in US deliver. In EU the regular micros are about 900W range give or take 200W (that is 1500W from wall because microwaves are not efficient machines) but kettles have usually range 2200..3000. So it is obvious why everyone uses kettles. I myselft have 3kW one and it heats 0.35 litres to boiling in 51 seconds. To have similar microwave it would have to be 3000W micro that is 4500W from wall and have not seen that kind of monsters, also regular 1 phase EU socket delivers max 3600W so that limits it also.

A typical US microwave draws 900-1100 watts too. I can't even find a 2000-watt microwave listed for sale in the usual consumer places. That'd be like a "pro chef" level luxury item, likely needing beefier electrical wiring and so on. US electric code requires a dedicated 20-amp circuit for microwave, which isn't supposed to serve a 2000-watt load.

Wh? It’s definitely less hassle, and maybe faster, to fill a cup/mug and stick that in the microwave

Than it is to fill a cup, pour that into the kettle, boil it, then pour it back in the cup. Or you have to put more water into the kettle than you need, because you can’t measure it accurateLet, and then it takes longer to boil

Standard wall outlet in the US is 15 amps, so a maximum of 1800 watts. 20 amp outlets (which can supply 2400 watts) are getting common, but I've seen very few home appliances that actually use the extra amperage (as determined by having a plug keyed for such an outlet).
