When you’re using the charger, fold these two clips back down so that they don’t snap off.
Until you’ve finished the wrapping process, just hold the wrapped large cord in place with one hand.
Make sure to also wrap the small cord around the already-looped thick cord. The small cord holds the larger one in place.
If there’s tension on the cord in this location, the cord could split or pull away from the charger.
At this point, your MacBook charger is completely wrapped up and ready to be stored
To use the duckhead, just bend down the two electrical prongs. Plug it into any outlet, and place the end of the small cord into your MacBook to charge it. You should have received a duckhead when you purchased your MacBook. If you misplaced it, replacement duckheads can be found online or at an Apple store.
If you hold on to one end of the cord and allow the weight of the charger to unravel the cord, you’ll place a lot of strain on the cable.
MacBook chargers aren’t cheap; they usually cost about $70 USD. Keeping your charger in good condition will maximize the charger’s life and keep you from having to buy a replacement.
