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 lead is provided with the adapter for maximum lead length, while the AC wall adapter (also provided) gives you an even easier and more compact way to travel.

    Designed to be the perfect travelling companion, the adapter has a clever design that 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

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.

      extremely fragile

      All you have to do is look at the thickness of the cord and you'll know it won't last long. I got 14 months of use before the cord split

She has to jiggle it a little to get it to charge. I bought the protection plan and I'm hoping it will cover the adapter.

      Fragile charger

Yes the magnet and LED is nice but 90$ is too much for a charger such as this. So i took some white electrical tape and fixed it up myself. It worked fine until it was stolen, so now i use a 3rd part charger; also with a magnet and LED for less than half the price of the official garbage. I highly suggest apple reinforce the two ends of the wire.
