AMAG website says there are 50 stations in the parking https://parking.amag.ch/en/parkhaus/zuerich/utoquai.html
Some of the chargers are probably only for long-term renters.
The only picture I seem to find of the AMAG chargers is a very low quality image on Google Maps that shows Zaptec units behind parking spaces that are not reserved for charging.
The location on Chargemap still shows the old evpass chargers that used to be in this parking. The evpass plugs are currently missing in my database. I'll need to dig in the historical data to retro-actively import the IDs and statistics.
Currently Swisscharge shows 42 IDs in roaming:
