Most power outlets I use are on my right so the cable runs parallel to the back of the computer then turns a sharp left to connect. I think my trouble has been caused by the sharp outside edge of the screen lid rubbing against the cable.

"The stresses against the natural coil work to twist the cable and eventual weaken the cable to the point of intermittent performance or total failure of the cable," he said via email. My MacBook Pro 13 is 2 years old now and my power cord has begun to fray close to the computer connection. It might not save space in your bag, but according to Albert Cardenas, Product Manager for Consumer Audio at Monoprice, the alternative is a shorter life. You can use the over-under technique, but just allowing it to coil as it came from the factory will also work. Instead, you want to loop the power cable with its natural coil.
Chris Apland, Product Manager for Gaming and Networking at Monoprice, told WIRED via email, "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." This puts unnecessary strain on both the pitch of the conductor and the shielding, he says. By tightly winding a cable around an object, you're forcing the natural coil of the cable and it'll begin twisting inside the insulation. It's also horrible for your power cord.įirst off, you're looking at cable fatigue.
It's a nice, compact way of keeping everything together. The Internet got super excited this past week after a photo of a MacBook brick with both cables wrapped around it emerged.
