The video explains how I wrap my extension cords. I recommend wrapping the cord around itself a few more times to make it tighter before connecting the male and female plugs. I normally keep my cords tighter than in the video. In case the video doesn't play here, I uploaded it to youtube as well. http://www.youtube.com/watch?v=RoqF2laKG8c&feature=youtu.be
Step 2: Wrap Cord Ends Around the Rest
Step 3: Plug the Cord Into Itself
Unlimited power, right?
