A portable contractor cart for use on construction sites that have not yet been hard wired includes a frame having front and rear wheels and arranged on the upper deck side of the frame from front to back are a 50 foot electric cord reel and a 50 foot compressed air line, an air compressor, an electrical generator, a refrigerated cooler and a weatherproof radio/cd player. A handle is mounted to the rear of the frame and a pivotable foot brake is interconnected to the rear axle for locking and unlocking the rear wheels, and the cart can be motorized wherein a motor and pulley arrangement would be mounted to the underside of the frame. Snaps are spaced about the periphery of the frame for attaching a covering thereto thereby protecting the cart when it is left outside on the job site. A welder generator for a TIG or MIG welder can also be mounted on the frame in place of the air compressor, and a trailer hitch can extend from the front of the frame for towing the cart from site to site.
