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?

    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.

    Hey Apple, have you fixed this glaring, consistent, and completely fixable problem yet?

    No?

    How about now?

    Shorted out in six months. Of course it's on a deadline week. Why must this cord be made like such cheap cr*p? I'd rather pay more Shorted out in six months. Of course it's on a deadline week. Why must this cord be made like such cheap cr*p? I'd rather pay more for a better cord that won't short out in less than a year.

    Own a macbook retina display. About 2 months ago I found the power cord had melted and looked burnt. The cord is normally on a til Own a macbook retina display. About 2 months ago I found the power cord had melted and looked burnt. The cord is normally on a tile floor, take really good care of my stuff so wasn't quite sure what had happened. Luckily I have apple care so the cord was replaced. Apple tried to charge me a 75.00 fee until I returned the power cord but I told them nope, not gonna happen. They sent the new cord anyway but no return package for the burnt up cord. Maybe a month later I saw the same little holes indicating the cord was getting ready to fail again. Contacted apple care, who again replaced the cord, big fight to get them to send it without charging me the 75. fee until I returned the old cord. When I told the service rep they never sent a return box for the previous one the smart @ss told me they didn't want it back, I could keep it, give it to a friend. I was like really, are you even listening to me, the cord BURNT up. Anyhow sent the whole macbook in for repair at this point, found heat sink and both fans needed replacement. I'm now noticing the same pre melting tension holes in my iphone cord that I charge via the laptop. This laptop has been the worst purchase I ever made and is my last macbook and probably my last apple purchase altogether. Give it to a friend, seriously???
