Visited yesterday without charging.
This is the first Partino station I am able to visit. I still don't know exactly what they do, are they the company installing & operating the chargers, or just doing the backend and support? The styling on this charger is very minimalistic, the word Partino isn't visible anywhere. There are just 2 QR codes, that do point to the Partino ad-hoc payment page on their website.
The charger is inside a parking lot without any signs. I suppose it's free.
The current ad-hoc price is 59ct/kWh. There doesn't seem to be any time or overstay fee.
To the left of the Partino charger there's an AC charger marked "Reserviert für swiss ecar".
