There has been a lot of noise around the Web claiming to have a great new way to wrap your Apple MacBook power bricks. They say it is a great space saver. Sure they, might save you some space, but don’t be fooled, this is not a good idea.
I planned on writing a whole post about this, but WIRED beat me to it. Basically the offending tip said you should tightly wind the long power cord around the brick and tuck it securely under the smaller wire. As Robert Baldwin of WIRED points out, this isn’t a good idea. It creates unnecessary stress on the wire and will lead to a shorter life of the cord. If that’s not enough reason, stress on certain parts of the wire could lead to an exposed wire, and that is a fire hazard. Read the WIRED article to get more specifics.
The best way to wrap or store any wire is to let it coil naturally. Every cord has a natural tendency to coil one way and forcing it to go another, or wrapping it tightly around something else will cause it to wear faster. Power bricks aren’t cheap, so I’d suggest using a little extra bag space and letting those cords coil naturally.
