A vehicle built-in electric jack system, including a plurality of electric jacks capable of lifting a vehicle. The plurality of jacks operates using a 12-volt power supply. The plurality of jacks are telescopic jacks. Each jack is made from a plurality of cylinders. The cylinders are apportioned such that each cylinder for a jack fits inside of the previous cylinder. Each of the plurality of jacks has a minimum of one light placed on the jack. The light is directed toward the wheel well of the vehicle. The jacks and lights are attached to a controller. The controller is located inside of the vehicle such that the jacks and lights can be operated while the user is inside of the vehicle cab. Further, each jack has a rocker switch located thereon that can control the jack to which it is attached.

Disclosed is a system for automatically elevating vehicles. The system is a substitute for standard, manually-operated car jacks, and jack stands. One or more systems may be installed underneath a vehicle. To lift a vehicle off the ground, the system utilizes a multi-stage actuator. The actuator may be powered, by either DC motor system, AC motor system, pneumatic system, or hydraulic system. The actuator is protected from distractive external elements by being situated inside a housing, integrating a retractable, electric door. The actuator is equipped with a high load universal joint, and attached thereto durable, non-skid plate. Acting in unity, the universal joint and the non-skid plate, ensures that the vehicle being elevated remains level on uneven ground, and during the operation of the Elevation System. The end-user may initiate the operation of the Elevation System manually via a control panel, or via a mobile application.
