CHARGER, DATA LINE AND CHARGING DEVICE

This application discloses a charger, a data cable, and a charging device. The charger includes a first Type-A port, a charging module, and a first PD transceiving module. The first Type-A port includes a data pin, a first terminal of the charging module is connected to the data pin, a second terminal of the charging module is connected to a first terminal of the first PD transceiving module, and a second terminal of the first PD transceiving module is connected to the data pin. In a case that the charger is connected to a matched first data cable, the first PD transceiving module is in an operating state, the charging module performs non-PD charging on a to-be-charged device based on a differential mode signal transmitted through the data pin, or the charging module performs PD charging on the to-be-charged device based on a common mode signal processed by the first PD transceiving module and transmitted through the data pin. The first data cable transmits a first signal transmitted through the data pin, to the charger when connected to the charger.
