Product Information

  • 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.

  • Better, but still not good engineering

It didn't. 18 months, and I'm having to wiggle the cord around to get power. Of course, Apple will sell me another one for $79, when my problem is that $1 worth of wire broke.

    Here's an idea: why not make the portion of the cable that attaches to the transformer detachable? Then when the connector frays, as it inevitably will, you could buy a $10 cord instead of paying $79 for the whole power adapter. But I guess that would eliminate a big source of profit for Apple.

    Dear Apple - stop being stupid. For such a great engineering company, why can't you get the obvious things fixed. These cords fray 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?

    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.

  • Terrible Power Cable

    I am on my 3rd power cord now, the flimsy cord separated and exposed wires where the cord mets the power block. I can count on on I am on my 3rd power cord now, the flimsy cord separated and exposed wires where the cord mets the power block. I can count on one hand how many time I have wrapped the cord around the block in 2 years. Just a terrible design. Why not make the cord replaceable with out replacing the whole power block.

  • My MagSafe Power Adapter became dangerous!

I had to buy a n Like many of the other loyal Apple folks, my late 2008 Macbook Pro 15" power cord has completely stopped working. I had to buy a new one for $80.00 and while I understand it's older they should not die this way. I have taken extra good care of this older Macbook Pro and it's been amazing except for the power cord where it connects to the MagSafe wire. It is really not safe at all. It seems as if it could become a fire hazard and also it would be easy to fix with better quality wire! So I sadly join the crowd and ask Apple to repair and redesign the power cords and connectors so we can all love our Mac's 100%! Apple I really hope that you are listening!
