A Roadster HPC to Model S adapter will be installed at Ellensburg and it should be accessible around August 8th. The adapter is on loan from the Centralia Burgerville Adapter Share group until the Ellensburg area gets their own Superchargers this fall. IIRC, Tesla is scouting Supercharger locations in the Ellensburg area at this time. After the Ellensburg Superchargers are in service the adapter will return to Centralia, unless another regional HPC is identified as a placement priority. The adapter is very useful if you have twin chargers on board your Model S because you can get over 40 miles of charge per hour. I don’t know what you should expect at the Ellensburg 70A HPC since I have not charged there yet. You can join the Model S/HPC Adapter Share Group for $30. PM “v12 to 12v” and “Puyallup Bill” for more information. Puyallup Bill is a team member that volunteered to cover for me when I am unplugged. Please try to give us 72 hours notice before requesting to join and use the adapter so that we have time to process your request and get the instructions and lock box combination to you in time. We typically can turn it around more quickly but there are times when we are out of range. Excess funds from the Adapter Share project will go towards incidental maintenance and repairs, if necessary. Beyond that any additional funds will be forwarded to the Port Angeles charging station. Once that need is met any excess funds will be forwarded to another regional project that has a need. Members of the group will be consulted when it comes to these decisions.
