Here in the UK electric kettles are cheap, sold everywhere and fast boiling.
That is not the case in the USA.
UK electric kettles are often about 13 amps load at 240 volts, or about 3,000 watts.
USA kettles are 120 volts, and normaly therefore limited to about 1,600 watts, that will take twice as long as long to boil a pint of water.

Electric kettles are probably much less in demand in the USA since filter coffee is very popular and is normaly made in an electric percolator, this should take some minutes and does not require a high powered heating element.
In the UK, tea is far more popular, and this requires a kettle, preferably fast boiling.

It would be possible in the USA to use a UK 240 volt, 3000 watt kettle, but this would require a special 240 volt outlet, and might be a violation of the NEC.
