Visited on August 10, charged with Swisscharge RFID without issue.
The DC chargers are in the outside parking and accessible 24/7. Parking is free.
The chargers are 2 self-contained Kempower, like in Riddes. Charger 280252/280253 is on the left, 280234/280235 on the right. In the Swisscharge system the chargers are named DC1 and DC2, but on location each "Parkplatz" has a number, with 1/2 being the left charger, and 3/4 being the right. These 4 numbers are only visible on the charger screen and not on any payment page.
There is no contactless reader. The QR code for ad-hoc payment is on the screen. It's a single QR for 2 connectors. It goes to a special page on the Energie360° website where you can choose 1 or 2, and are then redirected to the E360-branded Virta (Swisscharge) payment page.
The rightmost parking space is larger, but has no special marking.
The Coop Pronto shop has toilets. I don't know whether there's an agreement with E360 to use the toilets without any additional purchase. When the shopping center is open, there are presumably free toilets inside as well.
