Apple 45W MagSafe 2 Power Adapter for MacBook Air

  • 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 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.

      Poor build quality

Clearly, this is a fairly common problem as there are products sold online specifically to prevent it; I wish I had discovered them sooner, as this is an expensive cable to replace based on a design that any amount of testing could have identified as unsuitable for long-term use. Very bad form on Apple's part to have released such a shoddy product.

      Very Poor Build Quality

      I've had a MB Air for approximately 5 years. It's a great laptop and been very reliable. Unfortunately, the power adaptor is a poor design and the cable joining I've had a MB Air for approximately 5 years. It's a great laptop and been very reliable. Unfortunately, the power adaptor is a poor design and the cable joining the white block keeps fraying; I've had to buy 3 news ones at £65 a time. Given that Apple is supposed to be a premium brand, I would expect much better reliability, particularly given the price. Very unimpressed.

      Cable split near the MagSafe 2 connector

      On the whole I have been pleased with the MagSafe 2 power adapter for my mid-2013 MacBook Air. It is a good size, weight and form factor. The major redesign On the whole I have been pleased with the MagSafe 2 power adapter for my mid-2013 MacBook Air. It is a good size, weight and form factor. The major redesign element from the MagSafe 1 was the angle of the connection, under some circumstances it makes perfect sense. However, my usual workstation has the power outlets to the right of the desk, meaning that the cable often had a fairly tight radius curve around the back of the Air to the DC input on the left hand side. No surprises as to where the cable has split. I also needed a replacement MagSafe 1 power adapter for my previous mid-2011 MacBook Air as the cable on that split too. Hopefully the next redesign by Apple will incorporate a detachable cable on the DC side of the power adapter.
