Tesla has announced a smaller and revised Supercharger which it will start rolling out to cities throughout North America.

The electric automaker initially rolled out its Supercharger stations in many rural areas across North American in order to provide cross-country charging solutions. However, for residents of inner-cities, stations have often been hard to come by.

Tesla’s solution is a new Supercharger that is smaller and now delivers up to 72 kW of power to the vehicle, significantly less than the 145 kW maximum of existing Superchargers. Consequently, it will take about 45-50 minutes longer to fully charge a Model 3, Model S or Model X.

According to Tesla, “Supercharger stations in urban areas will be installed in convenient locations, including supermarkets, shopping centers and downtown districts, so it’s easy for customers to charge their car in the time it takes to grocery shop or run errands.”

Tesla has kicked off its roll out of new stations with one in Chicago and another in Boston.
