> power plugs with 16A [...] at 230V they can deliver 3600W/4600W That makes me a bit sad. We used to have a mess of plugs and sockets, with older plugs being either two round non-insulated pins or two equal-sized flat pins (sockets that could fit both kinds were not uncommon, but sockets which could fit only one kind were also not uncommon), and a Y with three flat pins for air conditioners, with NEMA 5-15 also being popular for computers (and we had sockets which could fit both the NEMA 5-15 "computer plug" and the other two types). We switched the whole country to a really neat new plug type (NBR 14136, see https://en.wikipedia.org/wiki/NBR_14136 https://en.wikipedia.org/wiki/NBR_14136 for a few pictures), but unfortunately it's only 10A (or 20A, but that's mostly for higher-power appliances like air conditioners; nearly all sockets are going to be the 10A variant, even though the 20A socket is designed to work fine with 10A plugs). Our voltage can be either 127V or 220V depending on which city you live in (yeah, both voltages use the same plug, but that was already the case even with the older plugs), and on how your building is wired (even in places with 127V you can get 220V by wiring phase-phase instead of phase-neutral), so it's not unusual to be limited to 10A at 127V which is around 1200W only.
