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 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?

      Junk, pure junk.

      Hey Apple, I love your products, but why can’t you make a power cord that lasts? I’ve had to replace the power cable 3 times, once every 3 years...

      How about a power adapter that lasts longer than a year?

      You don't even deserve one star. This is an annual purchase for me and it seems like I am not alone. Apple can do better.

      I have 2 MacBooks that need these: A 2011 and a 2012 model.

They are currently sharing whatever charger I have that works at the moment because they are constantly melting over many years and many purchases and it just hasn't proved worth it to constantly have 3 (one for each computer and a backup). I've also had one that just stopped working before it ever got the chance to melt (because they always do without fail). It's only a matter of when. The part that is the most likely part to melt, the section of cable right below the connector, is also the only part that isn't removable or replaceable. With the lack of OS support now for my 2011 and presumably soon my 2012, I am nervous that at some point access to replacement chargers will become a real issue if Apple decides to drop this product with no other working options going forward. Because other than this, my computers work great and I don't see them breaking down or losing functionality any time soon. The only issues I constantly have with them are the chargers, which I have to replace with the frequency of about every 1-2 years (and they WILL NOT last that long without strategic use of some electrical tape EVER). Pros: - The computers these are made for are the preferred models I own since I can open them up for RAM and hard drive problems with little interruption in my work week and additional costs of service. I did buy a second one and continue to put up with these chargers, which I constantly use and need for work. Otherwise, I would not put up with them at all. - The magnetic connector prevents damage to the computers themselves, the most valuable part of these purchases - When they do melt, they don't immediately stop functioning.. which buys me some time to patch or replace Cons: - It's a considerable and ridiculous expense to keep replacing these - Will not survive regular use without tape. It just won't. The cables WILL start tearing. - Electrical hazard also to your home, pets, and nearby valuables - Sometimes they just quit working without getting to the point of tearing - These have always been bad products with no improvements in lifespan in the 8 years I have owned them - Traveling with these cables further shortens the life of them, which is kind of the point of a laptop. I never unplug the one I use at my home desk. Guaranteed disaster. My travel adapter stays in my bag and is the one I use the least as a rule.
