A jack device includes a frame, a lifting assembly, a hydraulic assembly, a power unit, and a battery pack coupling portion. The lifting assembly is pivotally connected to the frame, one end of the lifting assembly includes a lifting pad liftable or lowerable, and the lifting pad provides an upward lifting force for a lifted object. The hydraulic assembly is configured to drive the lifting assembly to perform a lifting action or a lowering action. The power unit includes an electric motor, a reduction mechanism, and an actuator, where the reduction mechanism is disposed between the electric motor and the actuator, and the actuator is able to drive the hydraulic assembly to operate. The battery pack coupling portion is used for mounting a battery pack, where the battery pack supplies power to at least the power unit.
