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.

      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

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.

      Excellent!

      I have had this charger for four years and it has worked amazingly throughout. At this point there is slight tearing in the chord but It still works perfectly!

      Poor quality

      I had this charger for about a year and it started to detach from the laptop. Even when attached, I would need to jiggle it or push it into make it work and cha I had this charger for about a year and it started to detach from the laptop. Even when attached, I would need to jiggle it or push it into make it work and charge. It has now completely stopped working. Not worth the price at all!

      Lasted quite a while I guess... Now broken for no reason.

      I've had this charger since I first got my Macbook Air roughly 4-5 years ago. I have not had a problem with it until now. The cord just began to melt right wher I've had this charger since I first got my Macbook Air roughly 4-5 years ago. I have not had a problem with it until now. The cord just began to melt right where it attached to the adapter and now it is totally useless. It did last a lot longer than some other reviews are saying, and i've NEVER had the adapter disconnect from the power cord, but now it's time to get a new one.
