  • Electronic device and charging control method using the same
    Patent number: 10763683
    Abstract: An electronic device and a charging control method using the same are provided. The electronic device includes a power input port, a battery module, a power supply circuit, and a processor. The power input port is configured to receive an external power. The battery module supplies stored power to the electronic device. The power supply circuit has a default charging identification code. When the external power is supplied to the electronic device through the power input port, the power supply circuit obtains a user charging identification code through the processor and compares whether the user charging identification code matches the default charging identification code. When the user charging identification code matches the default charging identification code, the power supply circuit starts to charge the battery module.
