--> op de US site, deze optie zat ook al op de MX dacht ik ?
Model S comes standard with a 48 amp onboard charger capable of charging at the rate of more than 25 miles of range for each hour of charge. This is sufficient to recharge Model S overnight when connected to a common NEMA 14-50 outlet or Tesla wall connector. Every Model S benefits from Tesla’s expanding Supercharger network for travel over long distances.
This option equips Model S with a 72 amp onboard charger for a 50% higher rate of charge when paired with a Tesla wall connector on a 100 amp circuit breaker. Charge rates when connected to 120 volt outlets, 240 volt outlets and Tesla Superchargers will be unaffected."
