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 up; 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 lead is provided with the adapter for maximum lead 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 travelling companion. It 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 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.

Working out of the office (as you would expect on a laptop), the laptop and supply goes in and out of my bag daily, but I am VERY careful with these, more so that any other electrical device I have ever owned, but still it frays where the cord enters the power supply. I now consider this the yearly GBP5 monthly fee I need to pay for using my Macbook (which it works out to cost me).

      Usual Fraying - is it an in-joke?

      Frayed cable on mine means it now gets hot and fails. These are virtually a consumable. How can a company that prides itself on excellence not read the reviews Frayed cable on mine means it now gets hot and fails. These are virtually a consumable. How can a company that prides itself on excellence not read the reviews of this product and do something about it? It has to be some kind of industry in-joke?

      Apple, how could a cord be so poorly designed?

      My second MacBook Air power adapter is fraying, I am very angry that Apple does not replace the pitiful power cords for free and redesign the cords.
