People are noticing that Tesla CHAdeMO adapters in Europe (e.g., Great Britain, Italy, Germany, etc.) are very inexpensive right now. They wonder if a European CHAdeMO adapter can be purchased and used elsewhere (e.g., Japan).
The answer is
NO. Do not buy an Italian CHAdeMO to use in Japan, North America, or South Korea. It will probably
not work.
Despite the photo on the Tesla-Europe sites, the European CHAdeMO adapters have a Type 2 plug to attach to the Models S and X there. That plug does
NOT fit a North American, Japanese, or South Korean Tesla. Cars in those three areas use the Tesla Proprietary Connector (TPC charging ports and corresponding plugs).
The European (Type 2) CHAdeMO adapters actually look like this:
As you can see it has a different (larger) attachment plug that will
not fit a car made for Canada, Mexico, the USA, South Korea, or Japan. Too bad, because CHAdeMO adapters in Europe
are very inexpensive right now. (I suspect that Tesla is dumping them in anticipation of some kind of change. Perhaps because there is a new CHAdeMO standard connector coming from China+Japan? I don't know.
I believe that the CHAdeMO adapter pictured above will work in all the European countries, as well as Oceania (New Zealand and Australia, Hong Kong, and [now] Taiwan).
Why do so many Tesla websites have the wrong CHAdeMO adapter pictured? (I am not sure. I suspect it is just web-master laziness.) The TPC CHAdeMO adapter (used in Japan, South Korea, and North America) looks like this:
