Finding working-as-advertised chargers appears to be hard if not downright impossible. The situation does appear to be a little better if you own a Tesla, but if you own most any other make of EV you're going to have a bad time. From a hard requirement of a third-party app to pay, chargers using cables that do not meet spec, outright broken charging stations, issues with the apps themselves, and so on. Aging Wheels did an excellent video[1] on how frustrating the experience can be.

Battery running down? Go find a Supercharger station. If you're in a Tesla, it will even route to these automatically. It will tell you in advance how many chargers are operational, and how many are occupied, and it will reroute to a less busy station if available.
