It's very elegant and simple, nothing like the Chademo adapter so it should be much cheaper. Maybe $150? Model S and X owners in EU are paying for it now, I wonder how much? Maybe one of the EU S/X owners will see this and answer it. Unless Tesla is giving it away as Tesla is changing the plugs so no way S/X owners could access the Super Chargers without it.
All that's needed for the Model 3 is the software update to use the plug. Again that should be easy since the Model 3 in EU comes with the CCS plug installed.
The Vancouver Electrify America fast charging station will be my private Idaho...for while.
