Product Information

  • 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 w 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.

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 lasted exactly one year

    1.0 out of 5 stars

    I never had to replace my MacBook Pro charger after 4 years of use, and before then had a sony vaio and toshiba something, and tho I never had to replace my MacBook Pro charger after 4 years of use, and before then had a sony vaio and toshiba something, and those cords still show NO wear. I am careful with my stuff so this is upsetting.

    Just bought my replacement after exactly one year for over $120 in the Cayman Islands.

    The guys at the store recommended buying some electrical tape and wrapping the base of the thin cord to reinforce it (where one would wrap it around the prongs). They unfortunately see this too often. They also recommended first making a small loop, and then proceeding to wrap the cord around the prongs when storing the charger, to relieve any tension that would be caused by directly wrapping the cord.
