Check in on Plugshare. Let others know your return time if you are not going to stay with your EV while charging. ( if there is no WiFi or electronic device available leave a note on your dash with a return time. )
Do not overstay the posted charge time limit. Take what you need then move along.
Local EVers, do not hog local Chargers. Leave local chargers for the long distance EV travelers and tourists whenever possible.
Report any technical issues or damage at a charge station if applicable.
Wrap up EV Charger cables neatly. Pick up any liter. Don’t park in an EV Charger spot unless charging.
