High wattage appliances
3,000 watt rapid boil electric kettles are common place here in the UK, I wouldn't go back to the old fashioned 2,200 watt ones we used to have, it would take too long to make tea!
Power outages in the UK are rare in the extreme, the national grid takes care of peak demands, although I gather due to underinvestment in recent years they have come very close on a few occasions to not being able to meet demand. Last outage we had must have been over a decade ago, I was told by a neighbour that the neighbourhood's transformer had "blown up", so a very exceptional circumstance.
My washing machine's element on its own is 1,950 watt, a ~2,000 watt element is pretty standard for a washing machine.
I've got a pre-ban 1,800 watt Samsung cylinder vacuum, it was rated at 350 air watts, its quicker and sucks more dust out of the carpets than any other vacuum I've owned, admittedly, I only use it on full power while using the turbo brush, or if the filter is nearly blocked.
The European Union banned high power vacuums, the problem was manufacturers were marketing their vacuums on ever bigger motor power, some as much as 2,200 watts, some people had argued that they should have been putting a performance rating like airwatts on the energy labels to address that. I can recall looking at a vacuum that was over 2,000 watts, but was such a poor design that it was only rated at something like 200 airwatts, which was no better than some 800 watt vacuums could do, meanwhile some of the more efficient 2,000 watt machines could manage 400 airwatts. We are now limited to a max of 900watt, unless it has a bypass motor (wet and dry), or an extra wide wand head (commercial vacuums).
