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

Get help buying. or call 133‑622.
  • 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?

      Absolute rubbish

      Not even one year old and the cord to the computer has pulled apart at the transformer end. Gone through two chargers now and I am very careful not to bend this Not even one year old and the cord to the computer has pulled apart at the transformer end. Gone through two chargers now and I am very careful not to bend this. I can’t believe how expensive this product is and it won’t even last. I’m seriously thinking of going away from Apple products. There quality is nowhere near what they used to be. Very unhappy

      The wire is NOT the problem !

      Hi Gang! Honestly. I look at all the criticisms about the wire fraying by the brisk. I've seen it happen. My spouse has gone through THREE. WHY?? — All I Hi Gang! Honestly. I look at all the criticisms about the wire fraying by the brisk. I've seen it happen. My spouse has gone through THREE. WHY?? — All I need to see is how it's being wound. I've been a professional recording engineer for almost 40 years. Guess what? I never bought an extra power supply because I broke one. Only because I needed an extra in a travel bag or in another location in the studio. The folding clips are NOT perfect, so I can't give them 5 stars. And I think abandoning the MagSafe concept was a HUGE mistake, especially for pro musicians that have lots of people moving all around their gear. Parents of little ones too. But seriously folks: While holding the brick in one hand, take the unwound cable in the other, gently fold a small length of wire (2-3 inches) under and around one folding clip, leaving a service loop at the top of the brick that is not taught. Use a finger of the hand that is holding the brick to tuck the wire up under and against the folding clip to hold the wire in place without needing to yank it tight. Use the free hand to neatly wrap the wire around the folding clips without pulling too hard, or without it being too lose that it slides off the folding-clips. Go all the way to the end, making sure the small wire-wrap clip slides all the way to within a half inch of the end of the cable. Snap the little wire-wrap clip firmly onto a length of the wire that is already around the folding clips. DONE. My power adaptors have been in and out of tour busses, on and off airplanes, set up and broken down several hundred times a year. I haven't frayed a wire yet. Thanx Apple! f
