A type of portable chargers with power factor correction capability for use with electric vehicles comprises of a filtering rectifier module, an integrated circuit power supply module, a DC-DC PFC module and a DC-DC BUCK module. The filtering rectifier module has one input port and two output ports. The IC power supply module has one input port and two output ports. The DC-DC PFC module has two input ports and one output port. The DC-DC BUCK module has two input ports and one output port. The two output ports of the filtering rectifier module are connected to the input port of IC power supply module and the input port of the DC-DC PFC module respectively. The output port of the DC-DC PFC module is connected to one of the input ports of the DC-DC BUCK module. The two output ports of IC power supply module are connected, respectively, to the other input port of the DC-DC PFC module and to the other input port of the DC-DC BUCK module. This new type of portable chargers embodied with this invention can effectively reduce reactive power in the power system and develop greater power.
