First, the good news, Tesla cars are all over the place now, cutting down carbon footprints and saving the planet one car at a time. The bad news, as more and more cars hit the road, the limited supercharger spaces are getting stretched and charge speed can vary from one location to the next. Back in 2019, every time I went supercharging, the starting supercharging speed (power draw) was always over 100kw if I had less than 30% of battery capacity, of course assuming the supercharging site is capable of 120kw or 150kw at the time. Fast forward to 2021, I supercharged 5 times the past two weeks, 3 times in North Brunswick route 1, once in edison nj and once in East Brunswick nj. (Btw, I live in NJ, so it may or may not apply to your locations). North Brunswick never got above 60kw in three occasions even though I had less than 30% battery left, it took 80 minutes to charge 120 miles. I was getting around 26kw consistently each visit. Edison was worst, I was getting 22kw with 20% battery life left, although there are 6 cars out of 8 spots there. I couldn't take it so I drove 20 minutes to East Brunswick and boom, 130kw power draw and I charged from 20% to 90% in 40 minutes which is what I was experiencing in the past. I know there are variables such as battery remaining, ambient temperature, battery temperature, how many cars are sharing, etc, but one time I charged in North Brunswick NJ, there were 3 cars including mine out of 8 spots and it was 50 degrees, still got 26kw power drawn. Bottom line, have an expectation that the fast in and out charging that people spoke of may not happen everytime, try to give yourself more time when planning a visit to a supercharging, as well as additional time to be spent when doing a road trip. Not saying it'll happen to everyone, but it's much more likely to happen today than it was even just 1 year ago.
