Does Playing Music in the Car Consume Fuel?

[AlexanderLee]

Playing music while driving does not consume fuel. Here are the relevant explanations: 1. Reason: The music system uses power from the car battery. Once the engine is running, it generates more electricity than what the onboard electronics consume, with the excess being used to recharge the battery. Therefore, the fuel consumption caused by playing music is negligible. 2. The onboard power supply uses the battery's electricity: The onboard power supply connects to the power source through the cigarette lighter socket, utilizing the electricity stored in the car battery. This electricity is the surplus generated during driving, and when the car is started, it automatically supplies power to the battery, so there is no fuel consumption involved.
