Abstract
A power control circuit is disclosed. The power control circuit includes a first receiving circuit, a second receiving circuit, a first power supply circuit and a second power supply circuit. The first receiving circuit is electrically connected to a charging circuit and a first port and configured to charge a power unit according to a first port voltage. The second receiving circuit is electrically connected to the charging circuit and a second port and configured to charge the power unit according to a second port voltage. The second receiving circuit is further configured to be disabled according to the first port voltage. The first power supply circuit is configured to supply power to the first port. The second power supply circuit is configured to supply power to the second port. Thus, the power control circuit transmits power or data through different ports.
