The wave powered generator device and system provides a system for generating electricity using wave energy. The force exerted on the float body by the waves moves the float body in two directions, up and down. The float body aligns toothed rails with rail gears that drive the PTO. The toothed rails secured to the float body travel vertically in relation to the rail gears. The vertical motion of the neck and the float body moves the toothed rails in relation to the rail gears. Such vertical motion of the toothed rails rotates the rail gears to drive the generator to generate electricity. The toothed rails are located on opposite sides of the rail gears to generate electricity during bi-directional movement of the neck, the float body, and the rail gears.
