Apple 45W MagSafe Power Adapter for MacBook Air

Get help buying. or call 1-800-MY-APPLE.
  • 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.

      Worst Adapter Ever

      I am now on my third adapter for my Macbook Air 2011. The laptop is going strong and I love it, but my two previous adapters failed because the wire that insert I am now on my third adapter for my Macbook Air 2011. The laptop is going strong and I love it, but my two previous adapters failed because the wire that inserts into the body of the adapter rips apart due to usual wear and tear. They fall apart every 2.5 years and that drives me nuts. OBVIOUSLY. It's not worth buying a new laptop just because the adapter is a P of S, but paying the full price of $80.00 for this accessory item six years from the date of purchase is ridiculous. What a rip off.

I am so beyond disappointed that I am on the verge of getting rid of it. The chragers are the biggest headache and absolutely cheap. This adapter makes the entire computer junk. The quality is SO cheap in comparison to the Pro and it is so ridiculous. Run away from this disgustingly poor quality cord.
