  • 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 up; 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 lead is provided with the adapter for maximum lead length, while the AC wall adapter (also provided) gives users 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 with 15- or 17-inch MacBook Pro.

      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 won't Apple fix these awful power cords?

      Well, the answer is clear. They are horribly overpriced at $80 and they break every 8 months or so. Clearly a goldmine for Apple. In the past 3 years, I've h Well, the answer is clear. They are horribly overpriced at $80 and they break every 8 months or so. Clearly a goldmine for Apple. In the past 3 years, I've had one break near the magnetic end and one near the wall plug end. A third just mysteriously quit working, though it looks brand new. I am very careful with these cords, but it makes no difference. Also, they get dangerously hot. I had just talked my mom into switching from PC to Mac, but honestly now I might talk her back into a PC. I know these complaints are not new. Several reviews say the same thing. So when is Apple going to fix the problem? Or at least come up with a "Buy 3 Cords Get 1 Free" deal?

      Terrible design, ridiculous price

      I am now on my fourth power adapter (once per year on average). The high price is not justified given the frequency that one has to replace them.

      Beware if you have a MacBook Pro with Retina.

      Not perfect but its safer than those $23 something replacement...

      I have bought this new 85 W MagSafe 1 power adapter though my renewed MBP came with its own 60w adapter that I think was a good replacement brand. Though the r I have bought this new 85 W MagSafe 1 power adapter though my renewed MBP came with its own 60w adapter that I think was a good replacement brand. Though the replacement adapter is working so far with no problems I still decided to buy the original from Apple for safety reasons. I mean, I have read a few blogs about the original adapter that has overheated and worse, in some cases "fried" the motherboard of these very expensive MacBooks. There is really no perfect electric gadget, in time you will run into issues and worst scenarios it may cost your MacBook or your properties (your house fried too...) if it comes to a point that it does not work well anymore due to undue electrical or physical strain. So think of this, what more if it was just a $25 power adapter replacement from somewhere else. Would you take the risk? I won't. I'd rather spend more to feel safer than having to think about my safety or property every time. And about the issue of fraying with the original connector cable to the Mac or from the power adapter, well it is a business strategy. Apple wants your money, and it means business doing it. A detachable connector cable would be great like what they have for the 87W Power adapter for USB-C, it has bi-directional USB-C jacks for the cable and a dedicated USB-C port at the power cord. I too wish they would come up with that same design so we can always replace the cord and NOT the whole Power Adapter.
