How to Wrap a Power Cable the Right Way

Too many of us wrap a device’s cable in a tight knot around the power brick – something that savvy consumers never do. There was a photo online recently of a MacBook wire tied into a tight knot around the cable brick saying how nice and compact this way of keeping stuff is. No, it’s not nice, it’s horrible on your power cord.

It’s called cable fatigue, and we do it daily when we wind a cable around any object tightly. This way, the natural coil of the cable is forced to twist inside the insulation. Chris Apland, Monoprice Gaming and Networking Product Manager says, “When you roll up a cable against its natural shape it will fatigue the entire length of the cable and will twist in a direction perpendicular to the length of the cable.”

As a result, this method adds unnecessary and potentially harmful strain on the shielding and the pitch of the conductor, he adds.

The right way of wrapping up a power cable of any device is to loop it with its natural coil in a “over-under technique,” or the way it came from the factory. The latter may be the optimum solution for wrapping the cable to keep it compact and tidy. This may not be the most space-saving method for your travel, but you will work towards a longer life of the power chord. Let the chord be your guide, feel its natural flow and never force it to twist in unnatural shapes.

“The stress against the natural coil works to twist the cable and eventually weakens the cable to the point of intermittent performance or total failure of the cable,” says Albert Cardenas, Product Manager at Monoprice.

There is also an issue with the cables that we keep permanently attached between the power brick and the computer. When we use it to wrangle in a larger detachable cable, we actually add stress to its internal structure, as well. The cables have a tendency to fail at the ends, so it is best to avoid any tight wrappings at all.
