Apple 45W MagSafe 2 Power Adapter for MacBook Air

Get help buying. or call 0800-692-7753.
  • Overview

    The 45W MagSafe 2 Power Adapter features a magnetic DC connector so if someone should trip over it, the cord disconnects harmlessly and your MacBook Air stays put safely. It also 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 lights up; an amber light lets you know that your notebook 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 you an even easier and more compact way to travel.

    Designed to be the perfect travelling companion, the adapter 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 featuring MagSafe 2 power port.

      What an awful design Now on number 3 in <4years.

      The cause of replacement number 3 is the useless covering on the magsafe cable end. The slightest pinch in this, usually caused by being laid under the world's The cause of replacement number 3 is the useless covering on the magsafe cable end. The slightest pinch in this, usually caused by being laid under the world's lightest computer, and it crumbles. While it's crumbling at one point the sheathing slides up and down, breaking at subsequent points along its length. Which is bad - but it gets worse. You cannot detach the cheap cable from the expensive box of electronics. Seriously guys, 4 years and you've not addressed this yet. Bad design flaw! Get it? Making the product universal with only 1 cable change for the global market is a good idea. Making us throw away a working and expensive box because you can't get a cable covering right is a bad idea. Let me demonstrate: Let's ask a 5 year old how we could improve that, shall we? How about you makek the cable that disintegrates detachable from the big expensive box of equipment so my replacement cost each year is smaller? Or do Apple genuinely want to penalise their customers by failing to make the product properly in the first place and then compounding that by charging us unnecessarily for a part that is still working but that we cannot get off the end of the cable to allow us to replace the cable that needs changing? Seriously? Yes, it would still be a pain, but a pain that wouldn't bankrupt me.

      Poor Product

      I've had Macs for over 30 years. By far, the most badly designed accessory for any Macbook or Mac Air or Mac Pro is the AC adapter. No matter how careful you ar I've had Macs for over 30 years. By far, the most badly designed accessory for any Macbook or Mac Air or Mac Pro is the AC adapter. No matter how careful you are, the adapter breaks and shorts out long before it should; it's the Achilles heel of Apple products. At this writing, my early 2014 Macbook Air is like new, but the AC adapter just shorted out. Please, Apple, there's no reason for this.

      Poor design: bad angle, inadequate magnetic pull

      There are three problems with the new MagSafe: 1) the cable projects from the overly wide connector at a 90 degree angle. This means that if the computer and Ma There are three problems with the new MagSafe: 1) the cable projects from the overly wide connector at a 90 degree angle. This means that if the computer and MagSafe are not completely level, it falls out. So the "laptop" has to be "table top-only" if you want to charge it. Add this to the flaw (2) of inadequate magnetic pull, and it's a disaster. If there is any grit in the power outlet in the MBA, the weak pull is lessened. The charger constantly falls out. 3) The coating on my cable nearest the connector (perhaps because of its 90 degree projection?) got stressed and split. Now I need to buy a new one as the internal wiring is exposed. This has never happened with any Apple cable before, and I am a long-term user. It has to be the design of this one. Apple, please, go back to the old design of the brilliant MagSafe 1. And offer it for the 2013 MBA.

      It Just Stops Working

      I have had two of these chargers already in less than 3 years of having a MacBook Air laptop. The first time it was from the cord fraying and now this second ti I have had two of these chargers already in less than 3 years of having a MacBook Air laptop. The first time it was from the cord fraying and now this second time it altogether stopped working. I thought maybe this was just a scenario of me using it a lot but it seems like this is a very common issue. I don't see how Apple isn't doing anything to fix it after years of the same problem occurring with the same product. Now I have to order another $80 charger because the other $160 I spent only guarantees a year per charger I guess.

      Always wears down

      The first one I have still works after 6 years but its stripped everywhere. I bought a second one 4 years in and now that one no longer charges. So I'm on to my The first one I have still works after 6 years but its stripped everywhere. I bought a second one 4 years in and now that one no longer charges. So I'm on to my 3rd $80+ charger. I had a black MacBook for 6 years and that charger is still in perfect working condition. It looks like apple really dropped the ball on this. Just look at the reviews!

      Very bad quality and very expensive to replace

      I do some traveling with my MacBook Air so I was not surprised that the cable lasted less than 2 years. I have a (now discontinued) Thunderbolt display so I don I do some traveling with my MacBook Air so I was not surprised that the cable lasted less than 2 years. I have a (now discontinued) Thunderbolt display so I don't really need the power adapter since I now use mostly my iPad when I travel. I sometimes use my wife's Macbook adapter if necessary but now her cable is frayed and I will have to buy an $80 USD adapter so she can use her Macbook. The cable should be of sturdier quality for the price they are charging or it should be (much) cheaper considering that it is built to last less than a year if you constantly take your Macbook (and adapter) with you.
