    120V vs 240V.

    One has much more power available to achieve the same in a different time.

    For example: I can easily boil 0.5L to 100°C of water in about 2-3min.
    And the kettle is rated for 2kW.

      actually that the why they are slower. most plug in devices in the usa are limited to 1.5 Kw. weather you used a 120v or 240v current it would just change how many amps it draws

        Well yeah.
        But if both are rated for 6 or 8 Amps and can only supply 240 or 120V, you are bound to that.
        Thus the volts are important as well.

        2 kW @ 120 V is 16.7 A, which exceeds the 15 A limit on most household wiring in North America. To be able to achieve that you’d need to get a 20 A rated circuit installed by an electrician which means pulling out and replacing the wiring with a heavier gauge.

        The advantage of 240 V rating in the UK is that you can draw more power with less current, so you don’t need the wiring to be so heavy for a high power appliance like a kettle.
