Apple 85W MagSafe Power Adapter (for 15- and 17-inch MacBook Pro)

  • Overview

    The 85 Watt MagSafe Power Adapter 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.

    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 with 15- or 17-inch MacBook Pro.

    See this article for more details about choosing the right one.

    Knowing which specific Mac model you have is important. If you are running OS X Lion (10.7) or later go to the “” menu at the top left of your screen, choose “About this Mac” then click the “More Info...” button. Your Mac model and generation will be displayed.

    If you are running an earlier version of OS X, you can enter your serial number here to find out which model you have.

      Better, but still not good engineering

      I thought the magnetic connection would solve the problem with my previous Powerbook cord fraying. It didn't. 18 months, and I'm having to wiggle the cord aroun I thought the magnetic connection would solve the problem with my previous Powerbook cord fraying. It didn't. 18 months, and I'm having to wiggle the cord around to get power. Of course, Apple will sell me another one for $79, when my problem is that $1 worth of wire broke. Here's an idea: why not make the portion of the cable that attaches to the transformer detachable? Then when the connector frays, as it inevitably will, you could buy a $10 cord instead of paying $79 for the whole power adapter. But I guess that would eliminate a big source of profit for Apple.

      Dear Apple

      Dear Apple - stop being stupid. For such a great engineering company, why can't you get the obvious things fixed. These cords fray at the connector. ALL of them Dear Apple - stop being stupid. For such a great engineering company, why can't you get the obvious things fixed. These cords fray at the connector. ALL of them do. Sometimes at the power brick, sometimes at the Mac end. Then I have to go spend 80 bucks for another adapter - when all I really need is the cord. So do the right thing, and put a MagSafe connector on BOTH ends of the cord, and a MagSafe jack on the side of the power brick just like the one on the side of the computer. Then, I could (1) disconnect the cord completely from the adapter when it's in my bag, and not have to worry about the cord getting bent and broken where it connects to the power brick, (2) could have my choice of cord lenghts - maybe a short one for my desk and a long one when I travel, and (3) I could replace JUST THE CORD if it got damaged or worn, for something like 5 or 6 bucks instead of 80. What do you think? Would it be so hard to do?

      Yes for Unibody, No for older MBP's

      Own Early 2008 MBP and Late 2009 MBP. Works on the unibody, does not on my early 2008. The port on the new MacBooks are smaller and more shallow, this charger Own Early 2008 MBP and Late 2009 MBP. Works on the unibody, does not on my early 2008. The port on the new MacBooks are smaller and more shallow, this charger reflects this change and will not make contact with older ports found on non-unibody. Buyer beware, save yourself the hassle and find an 'I" MagSafe charger if you have a non-unibody.

      Consumable

      Expect to go through as many of these as you go through toner or inkjet cartridges. This is basically the disposable/consumable part of owning a Mac laptop. The Expect to go through as many of these as you go through toner or inkjet cartridges. This is basically the disposable/consumable part of owning a Mac laptop. The engineering on the connector is much worse than you'd find on a Lenovo, and the newer MagSafe 2's aren't much better. It's amazing with everything else being so high quality that Apple can't solve this.

      Life long customer put off because of this charger.

      I've gone through 3 of these poorly-made chargers. The first one's cord frayed. The second one's cord frayed. The third one shorted and was determined to be I've gone through 3 of these poorly-made chargers. The first one's cord frayed. The second one's cord frayed. The third one shorted and was determined to be "user damage" after 2 months of normal use. None of them were replaced by Apple. All Genius employees told me that these product faults were my own doing. A short -- an electrical fault -- was my doing. This charger will break. It will. There is no getting around it. Even if you never touch it, never unplug it, never move it, it will break. Be prepared to spend another $95 on a new one within 3 months of purchase.

      Designed to have a limited life

      I have the same complaint as everyone else. No matter how careful you are with these, the cord frays in very short order. It would be such a simple thing to fix I have the same complaint as everyone else. No matter how careful you are with these, the cord frays in very short order. It would be such a simple thing to fix. Make the thin MagSafe cord modular so that the whole unit doesn't have to be replaced. This is such an obvious fix that I can only assume Apple's not implementing it on purpose. Which makes no sense. Apple's a revenue-producing behemoth. Why sacrifice their reputation for quality on just this one product in order to earn what surely must be minor dollars to them. Note: Don't bother with the third party power adapters. They're even worse.
