"Charging a Tesla on 120V AC power—the power that comes from a standard European wall socket" Wait a minute ... in what part of Europe do they use 120V? Normal sockets in nl, de, be, fr are 230V AC. In at least nl what you are actually often getting is three-phase power to the door (typically marked as 3x220/230V or 380/400V ) . You can definitely get that three-phase extended to your kitchen, workshop, garage or what have you.

Yes, that is definitely an error. All the rest of the world[1] (not only Europe) is largely on 220/240 V AC (single phase) it is the (mainly north) American countries that are an exception.

  After some more googling: 120V mains with 15A breaker provides a max of about 1800W, while a 3-phase line at 24 A provides 16500W. That's almost an order of magnitude. This also means that the writer is also an order of magnitude off wrt how long it takes to home charge a (Tesla) in Europe: it's hours instead of days. This discrepancy may lead to an incorrect assessment of EV viability in Europe.

    Don't be so sure about that applying to Europe at large. To give you a counter example here (Italy) house electricity contracts are typically 3, 4.5 or 6 kW (a few contracts are 10 kW), you won't get easily a 20 kW contract in most places simply because there is not (yet) the infrastructure to deliver that kind of power to homes, and such "high power" contracts are - last time I asked - very expensive for the monthly fixed fees. As a side note, in order to have more than 6 kW there are a few added technical requirements (the electrical plant needs to be certified in a different, more strict way) that add costs.

      Fair enough. Europe is a big place.

  Japan is 100V, with frequency either 60Hz or 50Hz depending on which half of the country you're in.
