How many watts does it take to start a car?

Answer 1

The amount of power required to start a car typically ranges from 300 to 600 amps for the starter motor, which translates to approximately 3,600 to 7,200 watts, depending on the vehicle's voltage (usually 12 volts). However, the actual wattage can vary based on factors such as the engine size, temperature, and condition of the battery and starter. Once the engine is running, the power demand drops significantly.
