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.

      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?

      To those that have had problems...

      I've read several of the reviews about this charger. It definitely has issues. It gets hot while it works and will shut down if it's too hot. The cording also I've read several of the reviews about this charger. It definitely has issues. It gets hot while it works and will shut down if it's too hot. The cording also has been a problem, but I've had several of these chargers. My earliest one had a cable that frayed at the magnetic end of the cable. The cable just split open, and so I put a piece of heat shrink tubing over it, which held it for awhile. But then, if I used my laptop on the bed, I began to notice light gray flecks of rubber laying around. It was from the magnetic cord that attaches to your laptop, not the AC cord. The earlier cables were made out of a different kind of rubbery plastic. At some point, it will simply disintegrate on its own. Eventually, that power supply's cable lost almost all of its rubber coating on the entire cable, leaving bits and pieces of rubber anywhere I used it, exposing the braided shield. I bought another one and threw the old one away. The newer model's cable wasn't as flexible as the older model. It felt more or less like Teflon. It was a bit stiffer, but it hasn't frayed at all, and while the box itself still gets hot, the cable is holding up well. These power supplies for the most part are fairly reliable, unless you have one of the early models with the different cable composition. And yes, Apple needs to made a charger where the cable can be easily detached and replaced, especially if you travel a lot with your laptop. Also, be careful to not cover the charger box with anything so it can ventilate.

      85W MagSafe Power Adaptor

      Dangerous - everyone I know with a MacBook Pro has a frayed cord at either or both ends of the slimmer cord part that goes between the 'box' and the laptop. The Dangerous - everyone I know with a MacBook Pro has a frayed cord at either or both ends of the slimmer cord part that goes between the 'box' and the laptop. The wire overheats, burns through the plastic, the plastic splits...even if you wrap it in electrical tape, it eventually burns through that, then the wires burn up and disintegrate! This is the first time I've written a review anywhere...just have to warn people about the danger and ridiculous design. I've read reviews of the same problem in the review section of this website from the present going back 6-7 years. I'm surprised there hasn't been a recall on this in favor of all the Apple users who have purchased the product, rather than the experience I had of walking in an Apple distributor store and being told it was my fault for not winding the cord correctly (me using computers for 30+ years (PC and Apple) having this problem only with this Apple cord)!

      Not sure what all the fuss is about

      I have a 4.5 year old MBP and have 3 of these power adapters/cables. 2 for in the house and one on the road. I've NEVER had an issue with the cord fraying near I have a 4.5 year old MBP and have 3 of these power adapters/cables. 2 for in the house and one on the road. I've NEVER had an issue with the cord fraying near the magentic connector. It's been hit, and kicked at the coffee house numerous times. The rubber collar is in great shape. What are you folks doing to yours that I am not??
