If you're referring to Blink and Chargepoint chargers, then I'm not worried for Tesla at all. Both of these suck really badly and take forever to charge. I used to use these all the time for my electric Focus and would maybe get 20 miles charged in an hour. With my Tesla, I charged the car up to full in about 20 minutes and it sent me a text with 5 minutes left so I was able to grab a quick bite to eat.
