CHAdeMO is a dead standard. Even Nissan is discontinuing it. Unless you have a very specific need for a CHAdeMO adapter, I'd save my money and buy the Tesla CCS1 adapter when available in the US (soon) for $299 (rumored price).
I bought Tesla one in 2013 used maybe three times I would pass on getting one .. in the three times I used the station overheated and the charge speeds went down to L2 speeds ..save your money unless u really need
The CHAdeMO adapters are not always in stock in the Shop. Secondary market might be your best bet for sourcing one (eBay, Craigslist, etc.). I bought mine several years ago and use it most times I charge the car (ChargePoint DCFC near me is cheaper than Supercharger).
Well sure, that's true, but we're pointing out there will be no need to use those. Supercharger coverage is so extensive and so good and easy that there probably won't be a need to use any EA stations.
