I just asked ChatGPT, which of course isn't omniscient, this question: Do any EV chargers in the US take cash?

In the US, most electric vehicle (EV) chargers typically don’t accept cash directly. Instead, they rely on digital payment methods, such as credit/debit cards, mobile apps, or subscriptions to networks like Tesla Superchargers, ChargePoint, or Electrify America.

However, there are some chargers at locations like gas stations or convenience stores that may accept cash at the point of sale, where you could load money onto a card or pay at the pump to use the charging service. Some networks also allow payment through app-based services or by using RFID cards tied to a payment method.
