I haven’t watched the video sorry. I watched some but it’s an hour long, and I couldn’t find the section about connector types. But most people will charge at home 99% of the time. How long it takes or what plug you have then doesn’t matter.

My personal experience charging when out and about is that I have a car with a common connector and never have had to worry about if it’s supported. The charging stations normally support multiple types, and the apps that tell you where the charging stations are also tell you the connector types so you don’t waste your time.
