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.

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!

      Adapter has worked well for me.

      I've had my Macbook Air computer with its 45W MagSafe 2 power adapter for about 4-5 years and the adapter has always worked well. I've been in the habit of win I've had my Macbook Air computer with its 45W MagSafe 2 power adapter for about 4-5 years and the adapter has always worked well. I've been in the habit of winding the cord around the body of the adapter and storing it when I'm not using it. And there is a small (1 mm in diameter) opening in the plastic cord covering several mm up from the cord's collar at the adapter. This opening is at the place in the cord where it makes a sharp almost 180 degree angle as it comes out of the adapter and starts to wind around the body of the adapter. I"ve since started winding the cord around the flip-up hooks that the body of the adapter has for cord winding. However it still works OK.

      On My Third Adapter

      These things are of the poorest quality. I don't bend the cord and keep the adapter on my desk where the cord is always straight. Yet, every single one frays These things are of the poorest quality. I don't bend the cord and keep the adapter on my desk where the cord is always straight. Yet, every single one frays at the base where the cord connects to the power supply. I've never had power cords on any product come apart like this. Apple ought to be ashamed for not addressing this problem, which has been evident every since they went to the MagSafe design. Then, to add insult to injury you have to pay $85 (with tax) to get a replacement. I'm on my third one and when it comes time to upgrade my laptop I'm going to strongly consider the competition.

      Absolutely horrendous low quality product

      My MBA stands still on the desk...I don't move, therefore I do NOT plug it in or out...Nor do I touch it the Mag Safe adapter, but the cable only needed a few m My MBA stands still on the desk...I don't move, therefore I do NOT plug it in or out...Nor do I touch it the Mag Safe adapter, but the cable only needed a few month...read less than 3 - before it started to break. Brought it from the Apple store (original) , went back and complained. They couldn't do anything...I was plugging it in and out to much. I stressed it was only the third time...oh but you look strong:-( Maybe I had a room with mold..yes, that he said to me...My humidity level is 40-60%..only the Apple cables do this...contacted the EU consumer protection board, quote "The drown in complains regards Apple cables"..
