Abstract
The present invention discloses an electronic device charger, mainly comprising: a voltage converting module, a microprocessor, a low voltage detecting unit, and an over voltage sensing unit. When a rated output voltage of a vehicle battery of an electric vehicle is detected to be lower than a first threshold voltage by the low voltage detecting unit or found to be higher than a second threshold voltage by the over voltage sensing unit, the microprocessor immediately stops the vehicle battery providing electrical power to at least one portable electronic device owned by the driver of the electric vehicle. Therefore, the electronic device charger can not only save the energy of the vehicle battery while the vehicle battery is at a low voltage state, but also protect the portable electronic devices from being damaged by the electrical power as the rated output voltage of the vehicle battery exceed a normal voltage level.
