You talking about Apple? Pretty impressive, a bank of 70 free level 2 chargers at the Apple store, though they shut down at 7pm. Even though I can walk there I don't use them as I have 5kw at home which is more than anybody needs, and it turned out 1.8kw which I used for 2 years was also enough.I also noticed the difference in price between the nearby Cupertino Superchargers. However, it doesn't matter to me since I have home charging and free L2 charging within walking distance of my home. The only time I use Superchargers is when we're traveling away from home. When traveling, the services around the charging site are far more important than the fee for charging.
As such, I have not used these chargers, but I see them on my map all the time and they are full with other people, who presumably can't even get L1 at home and thus should care more.
When I have been by, I do see some model S and X, but the bulk are 3s and Ys, which don't have unlimited charging. And referral free charging stopped a while ago too (though I still have about 2,000 miles of it.) I figure better to save it for actual road trips than use it at home, since after it runs out, I will be paying the price, sometimes the 48cents, which as noted is more than gasoline in the hybrid car I would otherwise own. I don't like the idea of paying more than the cost of gasoline in my EV. (Though with the new price of gasoline it's less likely.)
