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.

      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.

      Not eternal, but functional

      I have to replace the 45W MagSafe 2 Power Adapter for MacBook Air, today, because the wire that connect to the charger is frayed. I got years of great service, I have to replace the 45W MagSafe 2 Power Adapter for MacBook Air, today, because the wire that connect to the charger is frayed. I got years of great service, and yes, things eventually break. The magnet always worked exactly the way it's supposed to -- trip over the cord and it releases instead of bringing the laptop crashing to the ground. I wish the cord part was modular, so I could just replace the frayed wire section, but it's not. And that's the price of constantly improving technology; for me it is worth $79 for the R&D and fantastic product design (and function!) that makes Apple products so wonderful. Oh, and I can either have it sent to me, for free, and get it in about 4 days, or mosey on down to my local Apple Store. Which is beautiful, and has hands-on displays of other stuff I want, and get information from the intelligent, knowledgeable, friendly staff. Or maybe are a FREE appointment at the Genius Bar, where they will explain what's wrong and fix it...

      Died in merely 2.5 years, Too expensive replacement

      Apple seems to have become the least reliable company these days. I've got some laptops from other brands that are still going strong, along with their original Apple seems to have become the least reliable company these days. I've got some laptops from other brands that are still going strong, along with their original adapters, even after 7-8 years of heavy uses but this is the first time I've been failed miserably by a laptop's adapter (MagSafe 2). I'm in a far remote, rural area right now, needing to urgently finish and submit a project and thanks to Apple, my project and week is ruined completely. NEVER PURCHASING ANOTHER APPLE DEVICE.
