Does charging in the car consume fuel or electricity?

[StTyler]

Charging your phone in the car consumes fuel. Principle of in-car charging: The electrical energy used to charge your phone in the car comes from the chemical energy of burning gasoline. However, since the current required for phone charging is relatively small, it consumes very little fuel—an amount that can be practically negligible. Additional information: Car chargers are accessories designed to allow car owners to charge their digital devices anytime, anywhere using the car's power supply. Some high-end car chargers typically include two USB ports, enabling simultaneous charging of two digital devices. These products generally feature overload protection, short-circuit protection, high-voltage input protection, and high-temperature protection—four safety mechanisms to ensure secure usage.
