Yes, but your Model S is only allowed to pull 40 amps from that 50 amp socket. That’s why they make the High Power Wall Connector for Twin Chargers that can charge at 80 amps, but it requires a 100 amp circuit and breaker.
On January 30th, Honda announced that Siri Eyes Free will be available “later this year” on the 2013 Honda Accord, Acura RDX and Acura ILX as a dealer installed option.
