I charged at Sweetwater one week ago (Dec. 26th).
I arrived, having charged at Cisco, with 156 miles of charge on my P85. I plugged into 3A and charged to 190 miles. The Kw was stable, starting at 56, then slowly tapering down a bit to 52 Kw by the time the charge had reached 190 miles. Since that was plenty for me to reach the Midland SC (taking into account winds and cold temperatures that evening), I decided to experiment.
I plugged into 3B. The Kw was immediately unstable, bouncing from the 40's to the single digits. I was only able to add 6-7 miles of range in ten minutes of charging.
I then plugged back into 3A, and to my surprise, I could scarcely get a single Kw from it! After several minutes of charging, I had not added even a single mile of range.
I then randomly picked another pedestal, 1B. Another surprise. Early in December, when I tried this pedestal, it charged with a low, unstable Kw, with very little output. However, on Dec 26th, it worked entirely normal. It was charging with a stable Kw in the high 40's, which is normal for my battery when it has about 200 miles of charge.
As for reports of vandalism to this SC: a few of the Tesla sign posts were vandalized since I had been there earlier in December. I did not see any vandalism to the pedestals, the inverters, or the inverter enclosure, including the locks.
