> Best charging experience
This isn't accurate - they charge slower and Plug & Charge is common in many vehicles now, including with the Tesla network - whereas Teslas cannot Plug & Charge on other networks.
Sure they can, you can buy a CCS adapter. You are limited a bit by 400V, but honestly I have never been able to not find a Tesla charger - and I’ve done 100k miles around the US over the last 5 years
(Up to) 250kW is fine in my Model Y - it’s always charged by the time my family has refreshed on a long trip.
Ironically - if it was faster I’d need to go move it in the middle of the bathroom/food stop.
In the UK most EVs use the standard CCS2 plug.
