Not all chargers use the same connectors.
It takes 50 minutes to reach 80% charge. Claims of faster charges are relatively untrue. Battery size matters not. Battery charge rate is the limit. We can "CRAM" power into a battery faster, at the expense of battery life and heat production. But topping off a battery requires lots of time, as the charge rate decreases as it "fills up".
50KWH is a solid 100 highway miles and 140 city miles in a Model 3 sized car.
EDIT: Tesla sandbags their batteries. In other words, the 100KWH capacity is really 140KWH+++, de-rated to 100. That way, as the battery degrades, and individual cells fail, the user does not notice significant problems. Also, Tesla can "improve" range with a software update, by allowing the battery to reach a higher state of charge.
Gentle charging results in much longer cell life and the cells can tolerate a great many charge cycles. We do know that time (years) degrade a lithium battery. So while modern cells may in fact be capable of 3000 charge cycles, we don't know what 10 years will bring. The best guess is that capacity will be seriously reduced in 10 years, regardless of charge method.
