Product Information

  • 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.

    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.

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.

With the first one the cable broke immediately "leaving" the adapter. The second one lasted one year. Suddenly began to became hot, very hot, and I quit using it.
    A shame an Apple product last one year in average.

Within this time I have replaced my charger 5 times due to it breaking. I treat the charger so delicately yet it still manages to stop working after a few months.
    Than again this is an Apple product.

I use my Air sitting in my living room in my easy chair with the power on the floor to my right of my chair. I have to run the cord in front of my knees, behind my Air and it reaches fine. Sometimes it disconnects if I kick the cord, or lift my Air up for a close look at the screen (old eyes) but so what? Plug it back in. I'd rather that, than my Air falling on the floor.

    And the charger still works like new after almost 3 years, as does the Air. This is my second MacBook Air (the first was stolen) after 2 Dell laptops, and there's no comparison. Everything about it is heads and shoulders above the Dell, including the charging device. I've kicked the cord more than once causing the Dell to land on the floor.

    I think long time Mac users are so spoiled, that the slightest little inconvenience upsets them. Maybe they need to get a life.

    I just bought another charger for my Air to pack for traveling.
