The maximum charging power of a Tesla V3 Supercharger is 250 kW.
Tesla introduced V3 Supercharging in 2019 to raise charging performance beyond the roughly 120–150 kW capability associated with earlier V2 equipment. V3 cabinets use improved power electronics and liquid-cooled cables, allowing a vehicle to receive a higher peak rate without sharing the cabinet’s power with a neighboring stall in the same way older systems did.
The 250 kW figure is a peak capability, not a constant charging speed. Actual power depends on the vehicle, battery temperature, state of charge, battery age, and site configuration. Charging normally tapers as the battery fills, so a car may reach 250 kW briefly and then draw less power.
A common mix-up is confusing V3’s 250 kW rating with V2’s commonly cited 150 kW maximum or with faster non-Tesla chargers rated at 350 kW. The charger’s capability also does not guarantee that every Tesla model can accept the full output.
