Apple 45W MagSafe Power Adapter for MacBook Air

Get help buying. or call 133-622.
  • 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.

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!

      Breaks way too often

      I have gone through 3 chargers since I've owned my macbook air. These chargers are not durable at all, so make sure you are extremely careful with it. Very disa I have gone through 3 chargers since I've owned my macbook air. These chargers are not durable at all, so make sure you are extremely careful with it. Very disappointed in the quality, considering the price. I have only owned my third charger for a year and it's already broken.. all I do is take my laptop with me to school and use it at home so there's no reason for it to break this fast.

      Please fix the cable flaws.

After a while, regardless of how carefully they're handled, the cable wears either at the Magsafe connector or at the point where it is connected to the power supply itself. We had one Pro that went through three supplies in 5-6 years and we've just ordered a second supply for a six-year old Air (which has actually been living on the spare supply from a dead Macbook Pro for the last year or two anyway). The cables all fail in the same way - there's obviously a real design issue here. Come on Apple, they're not cheap to replace so build them right!
