A Pen Spring Will Protect Your Charger Cords

A pen spring is that little spring inside a ball-point pen–you may remember them from grade school, when they were often used to make tiny rocket launchers.

Wrap two springs around a charger cord: one at the end that plugs into the outlet, and the other at the end that plugs into your device. Tighten the springs just enough to keep them in place (or use a piece of tape around the cord just below each spring). The spring will prevent the cord from repeated bending that ultimately leads to splitting, cracking and–if you’re really unlucky–sparks flying out of your charger cord and into your eyes.
