I am unsure on whether to get the dual charger option. My expected driving pattern from home is not enough to justify getting this option with the High Power Connector for home use, but I am unsure about longer road trips to places that may not have the Supercharger access. As I understand it, many J-1772 charging stations are set up with relatively low current circuits that are fine for the Nissan Leaf, but would not support the full 20 kW dual chargers for the Model S using the proper connector. I have checked all the online sites (Recaro, Plug Share & Car Station) and can find no details on which J-1772 charging stations would support an 80 to 100 amp circuit necessary for medium fast (60 mile per hour of connection) charging.
Does anybody have thoughts on this? The core question is how to find out where the high current J-1772 stations are located to make the decision on dual chargers for someone like me who only needs this function on the road and not at home.
