A power tool system includes a power tool having a motor, a battery pack, and an adapter. The battery pack is capable of outputting a voltage different from the rated voltage of the power tool to start the power tool. The adapter includes a first port connected to the battery pack and used for accessing a first voltage outputted by the battery pack; a second port connected to the power tool and used for outputting a second voltage; and a voltage conversion unit for converting the first voltage into the second voltage. The voltage conversion unit includes a switch unit connected between the first port and the second port; a capacitor connected in parallel to the second port; and a control unit configured to set the switching frequency or the switching duty cycle of the switch unit based on the parameter related to the current of the motor.
