Product Information

  • 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 cord is provided with the adapter for maximum cord length, while the AC wall adapter (also provided) gives you an even easier and more compact way to travel.

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

    Quite careful with my equipment. This one simply stopped working under no significant stress conditions. Quality control alert.

When I saw the reviews I thought they were joking. I feel like sending the entire laptop back because of the adapter. It falls off for no reason and gets in the way. Apple needs to do a recall.

  • Only read reviews of MagSafe TWO - it's TERRIBLE!

The new MagSafe 2 hasn't been available for that long - only since the new 2012 MBA's came out in mid-June. The new MagSafe 2's charger attachment magnet is incredibly weak and will detach at the slightest provocation. Or unhappy thought. Or suspicious look. This product is terrible and Apple should fix this as soon as possible.

No ser I'm very careful with all of my gadgetry, and the MagSafe 2 for my 11 inch MacBook Air broke after just over a year of use. No serious amount of stress, and no perceivable damage, just a poorly constructed charger. This wouldn't be so infuriating if it were also reasonably priced. VERY disappointed with Apple for this one.

    I was surprised to see the level of vitriol directed at Apple because of the design of the new MagSafe 2 connector. You would thin I was surprised to see the level of vitriol directed at Apple because of the design of the new MagSafe 2 connector. You would think Apple ran off with some of theses reviewers' children or something. My own experience with this power adapter on a new MBA: I agree the L design might be preferable because it is more low-profile and is less likely to get bumped. On the other hand, I expected a weak magnet based on the angry reviews. The magnet is actually quite strong as you discover when you try pulling it off directly. In fact, it seems much stronger than the L connector I had on my old MBP. Now, if you tilt it up or down, it does come off fairly easily as you are sort of leveraging it off. But that is probably a good thing as it will save your lightweight MBA from getting pulled off a table. So, it seems to be a good compromise. It certainly does not fall out the way some are describing. Maybe Apple strengthened the magnet in the last year? I don't know, but it seems strong enough. Since the battery on the new MBA lasts a long time, I never have a need to use it while plugged in. It gets recharged overnight. I mean, the whole point of using a laptop is portability, so I try to time the charging so that I don't need to have it plugged in when I'm actually using it. But, the adapter isn't as horrible as people are making it out to be. Now, I do wish it wasn't as expensive as it is...
