Charged here yesterday. Convenient to I-26! More than half the chargers were in use; looks like this will be a popular stop. There was a long line of cars at the fast food drive-through, right in front of the chargers, but I was able to get in and out okay. So, a great addition to the I-26 corridor, but a somewhat less than ideal spot otherwise.
While we were in Spartanburg, we visited the Hatcher Garden, which is pretty close to the superchargers. It's a very nice place for a short walk, to stretch your legs and take a break before getting back on the road. Recommended.
