Matt Beard· Driving yet another EV!
The Model S can charge at up-to 22kW on AC, but 135kW on DC. CHAdeMO is DC, normally at 50kW. I suspect that the Model S adaptor gives the car the 50kW DC and manages the CHAdeMO communications to the charger. This means that you will only be able to use it with cars that take in high-current DC on a type-2 connector and that seems to be limited to the Euro-spec Model S.
