Another trip to SF last night. Didn't charge enough at Buttonwillow so had to do Harris Ranch and Dublin instead (3 stops).
The Superchargers seem to be a bit faster, 107kwh / 328 mph when the car was at 125 miles.
My X was charging at the hotel's HPWC but it charged at 256 (my max rated range) for over 40 minutes. Why? (200V/40 Amps - connection)
