Clark Visited yesterday on foot. I had already noticed this charger a few months ago from the tram but was unable to take a picture. I don't know what the modalities are. I hope it's available for hotel guests.
Clark On Chargemap we see the same charger was already there at some point in the past when the hotel was called Walhalla https://fr.chargemap.com/hotel-walhalla.html At that time there was a green sign "P Elektro-Tankstelle" with the hotel logo on the wall above the station.
