Abstract
A charging path switching circuit includes a first port, a second port, a path switch unit, and a conversion unit. The first port is connected to an external electronic device to obtain a first electrical signal. The second port is connected to an external power source to obtain a second electrical signal. The conversion unit is connected the path switch unit and converts the first electrical signal or the second electrical signal to a predetermined voltage. The path switch unit is connected to the first port and the second port. The path switch unit selects to connect to the first port or the second port, to obtain the first electrical signal or the second electrical signal according to the connection of the first and the second port. The path switch unit preferentially selects to obtain the second electrical signal from the second port.
