The present invention discloses a dual-output port charging circuit and a control method. The dual-output port charging circuit comprises a primary switching circuit, a secondary first switching circuit, a secondary second switching circuit, a transformer connected to the three circuits, and a controller. The controller receives and samples an output voltage and an output current of the secondary second switching circuit, the output voltage and the output current are compared with a reference value, and a compensation is made, so as to eventually control an on-off time of a switch in the primary switching circuit; and the controller receives and samples an output current of the primary switching circuit, a zero-cross delay is calculated through a zero detection, so as to control an on-off time of a rectification switch in the secondary second switching circuit. The present invention uses one controller to flexibly control voltages of two direct current output ports with accurate voltage regulation and strong antijamming capability, and has the advantages of simple structure, convenient arrangement, small volume, low cost and light weight at the same time.
