It's also interesting to me that when one looks at many ChaDemo stations there is a very high number that seem to be out of service due to poor maintenance. Seems that filters get clogged and there is overheating. I have a Chademo adapter that I picked up when I started my cross country trip to Pasadena last June. It's still in the box with the seal intact. The Supercharger network was awesome. Always worked like a charm. The few larger gaps in the trip are starting to be filled in. The Supercharger in Columbia, MO went up recently so the long gap between St. Charles (St. Louis) and Independence, MO is plugged. The last longer gap is between Buffalo, NY and Macedonia, OH. Erie, PA is supposed to get a Supercharger but siting seems to be taking a really long time. Hopefully by next Summer that gap will also be filled. The minor inconveniences of charging are far outweighed (for me) by the pleasure of Tesla ownership.
