This one seems silly, but one really useful cheap thing I bought that I use much more than I thought I would is an electric kettle. (I should point out I'm in the US) I use it to make iced tea, my wife uses it for hot tea, and we both use it for boiling water for whatever cooking project needs it. We have a gas stove, and it takes about twice as long to heat up a liter of water as this kettle. It uses a normal US 120v outlet and I think it draws 1,000w. (Edit: I looked it up and it's 1,100 watts)
Seconding an electric kettle, even a cheap one was a game changer over not having one at all. Crazy how 99.99% of people I know as an American don't own one
Can't say I know what that looks like, but the US is a big place. There's a lot of different looks to it.
But even poor Poland Villages have electric kettles.
We do have them. You can get one at nearly any big box store. They're cheap too. Most Americans still don't own one because we have no particular need.
At 110V that's a 20A kettle. So you aren't getting that high of wattage kettle in the US. Most standard US residential breakers are only 20A (some are only 15A) and they aren't designed to continuously run near the max amperage so the biggest we can run on a "normal" circuit is probably around a 1760W kettle but it would also have to be the only thing running on that circuit at the time.
plus one and I use it for a lot of non cooking where you want water of a specific temperature. Unclogging drains and filling the carpet cleaner comes to mind.. Its like I want 135 degree water. Oh also nasal irrigation water. Its great for it to have a wide temperature setting.
