I went by a Tritium veefil 50kW charger last night that wasn’t hooked up to any apps but just had a credit card reader on the front of the unit. The credit card reader just said please insert card, but the screen on the charger is very basic and has no pricing details. Plugshare lists a price of 50 cents a minute, but I don’t see a way to verify that at the actual chargers. This is the charger I’m talking about https://smartchargeamerica.com/wp-content/uploads/2020/09/tritium-veefil-rt-50-electric-car-charging-station-EVSE-2.jpg
