I traded my 2016 X for a new 2020 one last month. I hit the road Sunday stopped at a hotel in Vail with a destination charger. The next morning, no additional power shown. They told me that it was indeed plugged in. Then we drove here to Utah to a resort with two destination chargers. Neither worked to charge my X. Weird. Plugging in to 110 was charging at just 3 miles per hour! So, I drove the car instead this morning a half hour to Page where there was a Supercharger, which completed the mission in an hour. What in the world is the story with these destination chargers and the new model X? The hotel here says it happened with another X too. Would have been a disaster if not for the Page supercharger.
