Apple 45W MagSafe Power Adapter for MacBook Air

  • Overview

    The 45-Watt MagSafe Power Adapter for MacBook Air features a magnetic DC connector that ensures your power cable will disconnect if it experiences undue strain and 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 will light; an amber light lets you know that your portable 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 users an even easier and more compact way to travel.

    Redesigned specifically for MacBook Air, the adapter is the perfect traveling companion. It 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 with MagSafe Power Port.

      Works Fine - BUT PRICE IS RIDICULOUS

      I've got a MacBook Air 13" (2011) that I feel is the finest travel computer for a businessman ever invented. I love this little workhorse. Also, the power ada I've got a MacBook Air 13" (2011) that I feel is the finest travel computer for a businessman ever invented. I love this little workhorse. Also, the power adapter on mine works just fine ... no problems. Instead of unplugging every time I hit the road, I thought it would be a good idea to buy a spare for my computer bag. Wrong! $79.95? Is this someone's idea of a joke? Eighty bucks for a power adapter? Sure the cell phone manufacturers have run this scam for years, refusing to standardize on a plug configurations/power ratings so that the buyer is forced to buy yet another power adapter (I've got about twenty of them sitting in a drawer). But those pieces of junk are only $20 or $30. $80? For what? I've got AppleCare, so I'll just keep on plugging in and unplugging the one adapter I have until it dies, then you can replace it for free. Really, you folks at Apple build the coolest stuff on earth, but you do need to re-think your policy of over-charging for the small stuff.

      4 months old, already failing!

      I'm a new Apple person, love the MacBook Air! But the power supply is already intermittent.

It is under warranty, but they will not pay me for the half-day I will spend going to the Apple store to get something that should last longer than the computer!

      My charger has worked fine from 2011 until now (2016)

      I am very happy with the quality of the cord. It is only now just showing the exposed wires. I bought a new one off Ebay because these here are so expensive, bu I am very happy with the quality of the cord. It is only now just showing the exposed wires. I bought a new one off Ebay because these here are so expensive, but it didn't last even a month. Now I'm going to have to buy this $80 cord. I'm hoping it's the same quality as the one I got back in 2011.

      It''s a Shame, bad quality

      The charger cable, plugs and everything are in perfect state but it just doesn't work, a $79 replacement is just too much considering the bad quality from facto The charger cable, plugs and everything are in perfect state but it just doesn't work, a $79 replacement is just too much considering the bad quality from factory but there is no option, so we are stuck on buying another one. Apple cables quality is the worst of all.

      As much as I love my Macbook Air, I hate the battery charging. I had trouble with the first cord and assumed it had a defect. But the new one functions just as As much as I love my Macbook Air, I hate the battery charging. I had trouble with the first cord and assumed it had a defect. But the new one functions just as poorly: I have to jiggle it, reinsert it, etc just to get it to start charging, and of course there is no point in moving it once you have hit the magic spot. As others have noted, it falls off at the slightest touch. It is sad that a product so excellent in so any other ways should have this as an Achilles Heel.
