They use different methods of putting heat into water.
A microwave turns the electricity into RF radiation that is absorbed by the water. To produce that radiation, the input electricity is converted to thousands of volts by a DC power supply. So regardless of whether it’s 120 or 230 input voltage, it all gets converted to the same high voltage DC to run the magnetron.
A classic electric kettle works by running the current from the outlet through a resistive heating element. Double voltage means double heat.
Induction heaters use a power supply to reduce the input voltage while increasing amps and frequency to heat metal through inductance. So, similar to a microwave, the voltage of the outlet is largely irrelevant.
Tl;Dr: microwaves and induction heaters change the supplied voltage to function, so they work the same in UK and US; resistive heaters work faster on 230v like the UK uses.
It’s only faster because your half ass electrical system is only 120V Also the microwave makes the mug to hot to touch
The electric kettle is still faster on 120v

And our stoves get 400V. Don’t pretend that your system is superior, it just isn’t.
And safety is a non-issue if you don’t stick your fingers in the outlets!
Even if you do stick your fingers in the outlets, it’s not a problem if you use a good socket
Especially if the entire house is protected by a GFCI.

You still get shocked by 110V, you don’t die from 230V.
Okay, so tell me about the pros, please.
So does an oxy acetylene tourch, what’s your point. Leave me with my glowing red hot coffee mug.
Wait how does the microwave go faster when it’s also on half the supply voltage?
