CHAdeMO adapters are included with every TESLA Model S purchase in Japan. I asked the same exact question about the weight to the DS. Response was they have been testing these adapters for some time now and no issues with the connectors to date and the adaptor is kind of heavy. Will update once I have my car in hand.....Approx. Dec 22nd...
So when is the big export from Japan to Europe starting? I wonder if the adapter works on a EU car. I'd even pay the shipping costs from Japan just to find out
