Yeah, come to think of it a coffee machine is solving a very similar problem to an electric kettle. Whats more, I’ve even used a drip coffee maker as a makeshift electric kettle before. So that was just a dumb argument on my part. Thanks for bailing me out with actual data on the diminishing returns of dumping more power into an electric kettle!
The UK versions from the same brand are 3000 watts, but only reduces the boil time by 1 minute.
I'm not sure about efficiency one way or the other, but it's interesting to note that double the power does not yield one half boil time.
Additionally, at this elevation I would estimate my morning coffee, Americano (Italian coffee that requires boiled water), takes less time to make than it would at higher wattage at sea level. I'm only guessing.
