The portable air conditioner has the advantages that the refrigerating capacity of the portable air conditioner is small, and when the portable air conditioner is used in an outdoor scene, the portable air conditioner can meet the user requirements only under the condition of the maximum refrigerating capacity. In the application, when the portable air conditioner operates in a timing mode, the target operation frequency of the compressor is determined through the control module according to the timing time and the residual electric quantity, the compressor is controlled according to the target operation frequency, the portable air conditioner can be kept to have the electric quantity within the timing time, the problem that the portable air conditioner does not have the electric quantity when the portable air conditioner needs to supply power can be solved, the compressor is controlled to operate according to the target operation frequency, the service time of the portable air conditioner can be controlled according to the residual electric quantity of the portable air conditioner, the compressor of the portable air conditioner can be enabled to operate at the proper operation frequency within the timing time, the portable air conditioner can meet the cold quantity requirement of a user to the maximum extent, and the use comfort of the portable air conditioner can be improved.
