One of the most frequent questions is “How long does it take to charge a Tesla?” and the answer is “That depends on the charger.” Here at the Pitkin County Public Works charger (across from the airport between the animal shelter and the bus barn) the charge is 20 miles per hour. At the Rio Grande parking lot in Aspen it’s 28 miles per hour. At the supercharger in Glenwood Springs it’s 280 miles per hour. We looooooove the supercharger.
