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.

    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.

      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 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.

      Why don't you fix your charger cable?

      I have tried to keep my charger cable stable, but it started to fray. Last time I went to Applestore because the charger stopped working, people at applestore w I have tried to keep my charger cable stable, but it started to fray. Last time I went to Applestore because the charger stopped working, people at applestore was like "oh, you are supposed to wrap the cable around the charger so it stays stable." I did that. My new charger is starting to stopped working agian. Why can't you guys make the cable thicker or add supporting element around where cable ends and starts? There are so many people writing reviews about that here. You clearly know the problem. Why don't you fix it? If you can't fix it, at least lower the price of charger. When you keep the price high and don't fix an obvious problem, you leave your customers thinking you don't care about your customers, just money.

      TOTAL Garbage Quality!

      I've had to replace 2 of these offensively overpriced pieces of junk now and my third one just broke! Total garbage quality and ridiculous price to pay to repla I've had to replace 2 of these offensively overpriced pieces of junk now and my third one just broke! Total garbage quality and ridiculous price to pay to replace. So glad Apple sells me a MacBook Pro 17" fully loaded for nearly $4K and the piece of garbage power cord, that if broken, renders the machine useless is almost $100 and lasts about a year, if I'm lucky. I'm careful with my cords too. I've managed to keep the machine in good working condition for almost six years, I wish the actual piece of equipment that makes the whole thing work had the same quality . . . Mercedes machine reliant on a Ford Pinto cord. Come on Apple, get it together. And if your business model is to sell a good machine and then rake in the dough on below poor quality accessories, then shame on you.
