I am about to take my first multi-day road trip and will need, at various points, to charge on "J1772" outlets listed in Plug Share. Whatare the actual charging rate I can expect? I know that in the case of NEMA 14-50 and HPWC outlets, the actual charging rate (Miles of Charge/Hour) depends on voltage. And I have seen 208 volts at a shopping center vs 220 or 240 in residential settings. I have an MS85 with Dual Chargers. I have membership cards for Blink and Charge Point, if there are differences between networks.
