I just traded my 2016 Model S for a new one and have two Gen 1 mobile charger adaptors that are now surplus. Available to the best offer in the next 2 weeks, or they go in the trash. They are NEMA 14-50 and 14-30. The latter is a common electric dryer plug. Anyone in the Ft. Lauderdale - Palm Beach, Florida area can pick up and avoid shipping cost.
