CHARGER, DATA CABLE AND CHARGING DEVICE

A charger includes a Type-A female socket, a PD charging processing unit, a non-PD charging processing unit, a data cable matching unit, and a first switching unit. The Type-A female socket includes a first communication pin. If the data cable matching unit determines, based on a matching signal transmitted via the first communication pin, that the charger is connected to a first to-be-charged device through a first data cable, and the first switching unit is connected to the first communication pin and the PD charging processing unit. If the data cable matching unit determines, based on a matching signal transmitted via the first communication pin, that the charger is connected to a second data cable or is connected to a second to-be-charged device through a data cable, the first switching unit is connected to the first communication pin and the non-PD charging processing unit.
