OK got it. I have also read that even if you were to use a Supercharger the most you'll get is 50 Kwh. Unfortunately, I know from experience that even 50 kWh is better than many of the stations you get through EA, EVGO, ChargePoint, Francis Energy, Blink, EV Gateway, and EVCS. I've plugged into all of those across the country - and they advertise 150 to 350 kWh - only to have it max out at 40 kWh. It's often accompanied by a message saying - limited by station or something along those lines.
So yeah, I don't want to use a Supercharger, but...needs must.
