Yes No. 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.
Character limit: Learn more Whether or not your adapter is still covered under warranty, you can take it to an Apple Authorized Service Provider or Apple Store for evaluation. When you route the cable, aim for gentle curves instead of angles.
The method called for wrapping the thicker cable—the one that connects to your outlet—around the power brick first, passing the cable in between the two plastic fins on the brick.

The most likely points where excessive bending can occur are near the adapter brick, or the MagSafe connector itself.
