I have 3 heavy cords like this one. I took an idea from the stores that sell bulk chains. For this big a cord use a 3 1/2 gallon bucket with a lid. Cut a hole along one side of the top close to the edge, another in the center of the top. put the male end of your cord through the top going inside, then bring it back out from the other hole. snap the lid on your bucket and pull about 2 feet of cord out of the bucket. Know push the rest of the cord into the bucket leaving the female end exposed. Push the 2' tail back into the bucket. When you need this cord pull out the tail and plug it in,grab the female end and walk to the job site. no unwinding or untangeling needed.
