    Common misconception about the voltage though, the US does have a 240v system (well in houses, some places have three phase power which gets weird). The breakers can be wired to give 120v or 240v. The large appliances like driers or electric car chargers and things that do need a large ampunt of current get wired up for that. It’s really only a slightly slower electric kettle to deal with as a minor inconvenience. Or maybe if you wanted an absolutely enormous electric space heater or something, but those are dangerous as it is. Not a lot of things used need more than the 1800 watt maximum. As far as I can tell it’s just a relic of history, Edison ran his generators at about 110v originally and that’s the voltage original light bulb filaments wanted and higher voltage filaments weren’t used until after the US had already been electrifying to a good extent. Theoretically 120v might be a little safer from a getting shocked standpoint, but electrocutions are pretty rare as it is, just a historical artifact and not a conscious design choice as far as I can tell (and yes, volts do matter too, not just amps. Especially if what’s being shocked has very high resistance, like human skin).

      I’ve used electric kettles in the US and Europe and they’re barely slower. I think the difference is overstated. It’s often used as the reason that fewer Americans have kettles but I think the real reason is just that Americans drink fewer hot beverages other than coffee, and most people have a machine for that.

      While 120v is safer for shocks I think the greater safety reason for 240 is lower fire risk which is more common and dangerous that shocks in either system.

        just get a hot water tap. boiling water on demand for serious tea consumption.

        Great for french press too.
