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.

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.

      I've never written a review before but this charger deserves one

So I went out and purchased another one and now 18 months in, I have to buy another 45W charger and this is utterly ridiculous. I'm at the point where people on the engineering team need to be fired for the poor quality that comes with the MagSafe 2 charger. I'm two seconds away from finding out who is response for the chargers and starting a petition to have them resign.

      5th Charger in Four Years

      I am very careful with my technology products and I have had to buy multiple chargers for my MacBook Air because the chord keeps breaking. The external material I am very careful with my technology products and I have had to buy multiple chargers for my MacBook Air because the chord keeps breaking. The external material bunches up toward the end of the charger, the internal wires detach, and the charger becomes inoperative. I am very frustrated with the quality of this product, given its high price.

      Terrible, but what are you going to do?

They heat up near the connect These cables never seem to last more than a couple of years, and for the last stretch are always held together by electrical tape. They heat up near the connector when in use (notably when doing anything processor-intensive), and over time the jacket starts breaking apart exposing the wires. I'm about to buy my third cable for a three and a half year old MacBook Air.
