Visited on Thursday without charging.
Apparently they decided to move the charger back here in December. I searched the Ringgenberg website but I did not find any new article about the charging stations.
According to the live data, the charger was moved from Parkhotel back here on December 8.
They put it back at the exact location where I had guessed it was in March. I never saw any picture of the original setup, but I would guess it was identical to what I saw this week.
Connector 14 is on the left, 18 on the right.
