CHARGER, DATA LINE AND CHARGING DEVICE

Disclosed in the present application are a charger, a data line and a charging device. The charger comprises a first Type-A connector, a charging module and a first PD transceiver module, wherein the first Type-A connector comprises a data pin, a first end of the charging module is connected to the data pin, a second end of the charging module is connected to a first end of the first PD transceiver module, and a second end of the first PD transceiver module is connected to the data pin; under the condition that the charger is connected to a matched first data line, the first PD transceiver module is in an operating state, and the charging module performs, on the basis of a differential mode signal transmitted by means of the data pin, non-PD charging on a device to be charged, or performs, on the basis of a common mode signal processed by means of the first PD transceiver module and transmitted by means of the data pin, PD charging on the device to be charged; and when the first data line is connected to the
