Visited on Sunday, failed to charge ad-hoc but was able to charge with MOVE RFID.
The ad-hoc page would accept payment but then get stuck at step "Charging session is being started". First time I tried while already plugged in, then I tried without plugging, but then my patience ran out.
The charger appears to be freely accessible but there's very little signage. There's no contactless reader, just the basic ChargeOne explanation and QR codes. No direct TWINT QR codes.
No parking space is painted with EV signage. There are 3 spaces that could be used, plus the unpainted space in front. All are truck-size.
There's a foundation for a second charger. But if it gets installed then I'm really wondering why they used 2-connectors variants when you can't really reach 4 vehicles total.
I couldn't verify whether the charger can actually deliver 400kW. There's no power indicated on the charger itself.
