My MacBook Air’s charging cord was basically destroyed after only about two years of owning it. I just kept putting black electrical tape around it but that only seemed to make it worse. I finally waved the white flag, went to the Apple Store and bought a new charger for a whopping $79. If you’ve been through this before, listen up, because Juiceboxx will help you out.
Juiceboxx is a plastic case that wraps around your MacBook’s power adapter and forces the cord to point straight forward at the base. That way when you need to wrap it up and go, the cord isn’t dealing with the stress of being bent and twisted. More importantly, your cord won’t fray as it tends to do, leaving you with more money in your pocket and one less trip to the Apple Store.
