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

Get help buying. or call 1-800-MY-APPLE.
  • 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.

      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?

It is extremely hard to change that part of the cable without changing the whole cable with the transformer, and I've done that twice already. It is pathetic the macbook pro lasts for like eternity AND the charger has to be replaced ~yearly. I really hope the person who came up with that design gets fired.

      Same frayed cable problems these have had for years

      This is possibly the worst cable I've ever bought for any device ever. I've been using Macbooks for about 10 years and these cables have all consistently had th This is possibly the worst cable I've ever bought for any device ever. I've been using Macbooks for about 10 years and these cables have all consistently had the same problem after 8-12 months. It doesn't matter if you've got a Macbook Air, a Macbook Pro, or just a Macbook. These cables all fail in the same way reliably at 8-12 months: the plastic splits near the Magsafe connection exposing the wires. The fact that its so consistent and has never been fixed suggests they do this by design. You're essentially forced to buy a new cable every year. How convenient (and profitable). No other cable I've ever used for any device has to be replaced with such frequency. The fact that you're even reading this review would probably mean your cable is frayed and you know exactly what I'm talking about.
