Mercedes-Benz said that its electric vehicles will be able to access Tesla’s Supercharger network starting in February.

US Mercedes-Benz EV drivers will be able to charge their cars at over 20,000 Tesla Superchargers in the US and Canada.

Electric Benz drivers in the US can use the chargers from February, but although the company will switch to NACS ports on new cars, existing owners need a $185 adapter
