Apple 45W MagSafe 2 Power Adapter for MacBook Air

  • 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.

    Knowing which specific Mac model you have is important. If you are running OS X Lion (10.7) or later go to the “” menu at the top left of your screen, choose “About this Mac” then click the “More Info...” button. Your Mac model and generation will be displayed.

      Broke too soon

      Quite careful with my equipment. This one simply stopped working under no significant stress conditions. Quality control alert.

      Worst Apple product or accesory

      This is like a bad dream. When I saw the reviews I thought they were joking. I feel like sending the entire laptop back because of the adapter. It falls off for This is like a bad dream. When I saw the reviews I thought they were joking. I feel like sending the entire laptop back because of the adapter. It falls off for no reason and gets in the way. Apple needs to do a recall.

      Only read reviews of MagSafe TWO - it's TERRIBLE!

      All these reviews saying they've had no problems for over 6 months are reviews for other models. The new MagSafe 2 hasn't been available for that long - only si All these reviews saying they've had no problems for over 6 months are reviews for other models. The new MagSafe 2 hasn't been available for that long - only since the new 2012 MBA's came out in mid-June. The new MagSafe 2's charger attachment magnet is incredibly weak and will detach at the slightest provocation. Or unhappy thought. Or suspicious look. This product is terrible and Apple should fix this as soon as possible.

      Overpriced and short-lived

      I bought my Macbook Air in fall of 2013.

Here it is, summer 2016 and I'm on my second Magsafe adapter (cable casing ripped on the first one), which separated where the cable meets the MagSafe bit that attaches to the computer. So I'm about to buy charger cable no. 3. That's ridiculous. It's an insult to the consumer to sell something that fragile, and an offense to the environment to produce products that short-lived. I like so much about Apple products, but their drive to instant disposability is truly sad.

      Poorly Made but Does the Job!!

      I've had my MacBook Air since December 2012 and am just now replacing the power adapter! Just like any other Apple charger, it's made very poorly as far as the I've had my MacBook Air since December 2012 and am just now replacing the power adapter! Just like any other Apple charger, it's made very poorly as far as the casing goes and tear easily if not properly taken care of (mine tore almost in half while moving this past week). However, after almost 4 years, I have had NO problems with the way the adapter charges my computer, which is it's main job!! Annoying that they tear and are so expensive, but still work very well!
