  • 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.

      HORRIBLE

      This truly could have been designed wayyyyy better. The wire frays fairly easily and the unit almost always overheats. I am frustrated and I don't know what to This truly could have been designed wayyyyy better. The wire frays fairly easily and the unit almost always overheats. I am frustrated and I don't know what to do. The laptop is great, the charger not so much.

      Amazing!!

      I’ve had my MacBook Air for 2 years now and I’m using the same adapter that the box came with. Still in great condition! I recommend it!

      Ugh

      You have to use this is you have a new MacBook Air, but it is frustrating to the max. It absolutely will not stay plugged into the laptop unless you are not usi You have to use this is you have a new MacBook Air, but it is frustrating to the max. It absolutely will not stay plugged into the laptop unless you are not using it, and not breathing and there is not a fan on in the room. Only slightly exaggerating. It is the worst. Impossible to use while you are using your MacBook on your lap. The slightest move makes it come unplugged. Slightest at all. I miss my old MacBook Pro and it’s charger plug.
