Abstract
A battery powered, electric motorized cart and burden carrier which may be manually pushed or pulled to a shopping area for use during shopping and for transporting merchandise thereafter. Battery powered motors and gearing associated with the rear driving wheels are controlled from a control box on a lanyard attached to the cart so that the loaded cart may be either operated and controlled by an individual walking in front or the rear thereof. Steering is effected through the swivelly mounted front wheels by the operating exerting a tug on the lanyard or applying forward pressure to the rear of the cart when the control box is arranged and supported thereat. Battery charging may be accomplished by actuating a control box switch to close the circuit to the battery and manually pushing the cart to rotate the motor shafts and cycle the amperage back into the battery. Another way is to utilize an alternating current charging adapter.
