I'm replacing my Nissan Leaf lease with a Model S. I've already got a 30 amp 240v J1772 charger on my wall. Can I just use the little adapter they give you in the Tesla trunk kit and charge the Model S with this EVSE? I'm getting about 6.6 kWh per hour charge on the Leaf. Would I get the same on the Tesla or do they throttle it down? I'm not sure if I'm going to go with the Supercharger option if that matters for this discussion. Thanks!
