I am traveling next week and I will be flying out early in the morning. The airport has ChargePoint chargers in the parking garage that are free for use to EV drivers. I have never used a public charging station and I was hoping that someone can give me any hints or tips about using ChargePoint chargers. In addition, I don't want to have to spend 20 mins trying to figure out how to use it and stressing about catching my flight. The ChargePoint app says that they are all available currently and not reserved for tomorrow. Also, I do have a ChargePoint account but they haven't sent me my card yet. Can I do everything from the app without the card? Are there any common issues that people have seen using these that can help me expedite my usage?
