Most of the ChargePoint and other chargers are 6-8kW. SuperChargers are 100-120kW... they are more than 10x faster to charge. It's the difference between 10min for 100mi 2hours!

That means that even with absurd 6mph traffic that takes 3 hours to get 30mi, you might still finish charging first on the SuperCharger (15min vs 3hours).
