Apple 45W MagSafe 2 Power Adapter for MacBook Air

Get help buying. or call 1-800-MY-APPLE.
  • Overview

    The 45W MagSafe 2 Power Adapter features a magnetic DC connector so if someone should trip over it, the cord disconnects harmlessly and your MacBook Air stays put safely. It also helps prevent fraying or weakening of the cables over time. In addition, the magnetic DC helps guide the plug into the system for a quick and secure connection.

    When the connection is secure, an LED located at the head of the DC connector lights up; an amber light lets you know that your notebook is charging, while a green light tells you that you have a full charge. An AC cord is provided with the adapter for maximum cord length, while the AC wall adapter (also provided) gives you an even easier and more compact way to travel.

    Designed to be the perfect traveling companion, the adapter has a clever design which allows the DC cable to be wound neatly around itself for easy cable storage.

    This power adapter recharges the lithium polymer battery while the system is off, on, or in sleep mode. It also powers the system if you choose to operate without a battery.

    Compatible only with MacBook Air featuring MagSafe 2 power port.

      Poor Product

      I've had Macs for over 30 years. By far, the most badly designed accessory for any Macbook or Mac Air or Mac Pro is the AC adapter. No matter how careful you ar I've had Macs for over 30 years. By far, the most badly designed accessory for any Macbook or Mac Air or Mac Pro is the AC adapter. No matter how careful you are, the adapter breaks and shorts out long before it should; it's the Achilles heel of Apple products. At this writing, my early 2014 Macbook Air is like new, but the AC adapter just shorted out. Please, Apple, there's no reason for this.

      Charger broke within 4 months

      After transporting my charger in my backpack, I was surprised to have found the cord to be frayed. Looks like a lot of people are having quality issues as well.

      Disposable charger

After using it for 2 years (not doing anything out of the ordinary, always coiling it loosely for transport) the area around the magnetic connector began to fray and a few days later the area coming out of the square adapter started to fray. Within a week of the fraying the charger stopped working. The other end of the charger (from the square adapter to the power source) is perfectly fine and shows no signs of wear. This has happened with every single macbook charger I have owned over the years (6 in total). I have both an HP and a Macbook. My HP charger has lasted for nearly 5 years, shows no signs of giving up and only costs $15 to replace. Having to pay $80 for a charger that is essentially disposable from a company that prides itself in quality, ingenuity and integrity is ridiculous. I love my apple products but something should be done to fix this problem and keep plastic out of landfills. It's a cord and if HP can do it, Apple should be able to do it.

      4 years - Same charger!

      I write this review only to contrast the others. I've had my Macbook Air for 4 years soon. Its been charged everyday, used for many hours everyday. Transported I write this review only to contrast the others. I've had my Macbook Air for 4 years soon. Its been charged everyday, used for many hours everyday. Transported almost everyday. And my battery and charger has been working all this time. I'm not careful, but not overly reckless either. I just stuff things down in the bag and go. This charger is NOT bad quality. It is good quality. That is to be expected for the price but the people on here saying that its bad must be chewing on the cord or something. Mine is just now beginning to break a little in the cord. After constant use and abuse from 3++ years? Thats good quality!
