Also worth putting some factual data against some of the claims made about rapid charge rates. For example, the CCS connector used here and in Europe has an absolute maximum current rating of 500 A, with liquid cooling. With a battery voltage of around 400 VDC, the absolute maximum rate of charge allowable without exceeding the connector rating is 200 kW. It is physically impossible for a UK/European rapid charger, that uses a CCS connector (as all new UK and European Teslas do) to charge at more than about 200 kW into a car with a ~400 V battery pack.
Cars that have a higher voltage battery pack can take advantage of the higher charge rates offered by some rapid chargers. For example, the Porsche Taycan has a battery voltage that's around double that of any Tesla, so in theory could charge at double the power for the same connector current limit.
Because of the absolute maximum connector current limit, and because all rapid chargers must ensure that the current through the cable and connector doesn't exceed this limit (it is a safety certification limit) then none are going to be able to charge a Tesla at more than about 200 kW, even if they have a theoretical rating that's higher. It may be that the connectors used in other parts of the world have a different rating, I've only checked the UK and European CCS specifications.
The higher powered DC chargers are capable of delivering higher voltages than those used by current generation Teslas (and other makes) though, so it's quite probable that they will, in the future, be able to charge cars at a higher power level, if the use of higher voltage battery packs becomes more common.
