A battery driven reversible motor and speed reduction gear assembly coupled to a worm-screw scissor jack, all mounted on a flat, stable platform (base plate) for use in raising and lowering the corner of a vehicle. The device can be powered from a rechargeable battery pack or from the vehicle's battery. A controller unit extended by means of a cable is used to raise and lower the vehicle while the user stands out-of-the-way in safe location. The device also has a light for illuminating the work area for nighttime application. In use, the lift plate on top of the scissor-jack is placed under the frame or axle of the vehicle close to the flat tire and the power switch is turned ON.
