I was just browsing the Tesla Store and I noticed that there is a 'Roadster High Power Wall Connector to Model S Adapter' up there now. Wasn't there last time I checked, and I didn't see this posted on the forums yet. Not sure if this is the right category for this thread or if it should be moved over to the roadster forums lol
