I stopped at this charger last night as we were returning from an event in Baltimore. We never got more than 39-40 Kw of power from any of the stalls, and I tried several. There was only one other car (a Tesla Mobile Service Model S) charging in another stall. We rolled in with about 40% in the battery and wanted to charge for only about 10 minutes or so. I had expected to get around 50 - 60 Kw at least, given my battery was at 40%.
It was late last night (10 pm) and I didn't want to call Tesla and be on hold for 30 minutes to report it (as has been my experience that last few times I've called to report SC issues).
