I had already created this location on my map back in June 2020 based on information seen on Chargemap but it seems like it was incorrect. I have still not been able to visit at this time.
The location is listed on the "old" map on Migros website with 4 plugs.
On Chargemap the location is listed with 12 T15 plugs, but the pictures all show 2 m-way ebox stations.
On GoingElectric the location is listed with 4 22kW T2 sockets and 6 T13 plugs. Here again, the pictures all show 2 m-way evbox stations. There is a check-in from november 2014 for a Renault Zoe at 11kW on T2, which is also the date of creation of the location on GoingElectric.
The description on GoingElectric says "all plugs" have been upgraded to 22kW stations in September 2018. Not sure if this means the 11kW stations became 22kW or if it went from 2 to 4 chargers.
Since there is not a single picture of 4 stations visible together, I assume they are found on different floors. The comments seem to say those are on floors 1 and 3. A Chargemap comment from "last year" still mentions the T15 plugs as well in the other parkings. I wonder if those are/were official plugs or just random plugs not meant for charging.
