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.

    I thought the magnetic connection would solve the problem with my previous Powerbook cord fraying. It didn't. 18 months, and I'm h I thought the magnetic connection would solve the problem with my previous Powerbook cord fraying. 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?

    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.

    I never, ever write reviews for products, but I felt compelled to echo what so many others have stated. The little cord managed to I never, ever write reviews for products, but I felt compelled to echo what so many others have stated. The little cord managed to wrangle itself from the brick enough to no longer charge my laptop unless I hold it and force it back in. The protective sleeve is okay, but obviously the internal connection has been severed/damaged somehow. Please make the cord magnetic on both ends, or simply make it a plug in (like the wall cord), that way we can buy a $2 replacement cord instead of the $79 unit. I know why that will never happen though...

    I'm a "MAC" as the old commercial says. My PB Pro is the 2009 mid-yr version. I use to go thru powercords
    like they were water I'm a "MAC" as the old commercial says. My PB Pro is the 2009 mid-yr version. I use to go thru powercords
    like they were water going thru a sieve. I went thru so many on my older MB's that I ordered them 2 at a
    time so I'd never be without one. Then, I bought this MBP and as was my custom, I ordered a spare
    power plug at the same time.

    I don't know what all the negative reviews are about. It's now Spring 2014, just a few months short of 5 yrs
    since I bought this MB Pro. A couple months ago, I finally replaced the original power plug because the wire
    broke at the white adapter (square).

    This was MY FAULT. I use my MBP in bed and almost always run off the power supply, rather than the battery.
    However, because of how it gets used, everything is constantly being moved around and the block can very easily
    slide off the bed. It took 4 and 1/2 + yrs of this jerking and hanging to finally break the wire within the cord at the block.

    Also, I have 2 little dogs who get tangled in the cord--no problem! The magnetic connection releases so no one
    nor any equipment gets hurt. I love the magnetic connection, it put an end to replacing the power supply every
    6 mos. or so.

    I don't understand the problems everyone is having.

    My block only gets hot if it's been buried under bedding-- unlike the old ones. If that happens, when I notice it,
    I move it out and it immediately cools off.

    If you use the little "catch" (cord minder) a few inches off the magnetic plug to form a loop in the cord,
    there's no stress (bending) of the wire at the plug. Also, it's a good idea, as with any electrical cord, to not
    allow it to get twisted-- or should I say stay twisted. It only takes a second to untwist the cord when that
    happens. You can't expect to continually twist any wire without it eventually breaking.

    Perhaps people need to be a little more aware of how they treat the cords or, perhaps, the supplier or specs
    changed since I got mine but I sure can't complain about the quality of the ones I bought almost 5 yrs ago.

    Always breaking. They do not last unless you never ever move them.
