The Icicle Creek charger served us fantastically well for the long weekend. We were apparently the only EV there this weekend, though my kids did see one other Tesla passing through town on the 3rd.
We don't have dual chargers, and haven't had the need to look at the CHAdeMO adapters, yet. Had to live with about 24 miles/hr. Left a note with my number on the dashboard for any other EV users while I was charging, but didn't hear from anyone.
