Visited today and successfully charged on connector B.
The parking spots are not marked, it's in front of the business. Not sure what the situation is like during work hours. There was absolutely no one when I visited today (Friday but holiday)
The eCarUp description asks to park backwards, but I don't see any reason why this might be needed. If your car has the plug in front you wouldn't be able to charge...
I was not able to test how much power can actually be delivered as my battery was quite full, I only charged at around 23kW limited by the car. The spec sticker on the side says "rated power: 120kW", voltages 150VDC-1000VDC and cables limited to 200A. On eCarUp it's listed as 2 80kW connectors.
The screen of the charger says the price is 1 CHF/kWh, and uses that value to compute the "Total cost" shown while charging. But that's not the real price. The eCarUp price is 0.60 CHF/kWh + 1 CHF/h, and that's what I was actually billed. I assume the 1 CHF/kWh is a default value they didn't change.
The QR code for ad-hoc charging is both printed on the charger and also displayed on the screen when choosing a connector.
I didn't find any evidence of why it's called "Super Duper Charger". "FuturePower" is the name of the business, and the charger model itself doesn't seem to have a proper name. I guess someone was just having fun with the naming when adding the charger to eCarUp.
