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?

    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 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.

    I have had to replace my power cable twice already and the third one is on its way out. Why do you make us pay so much for poorly I have had to replace my power cable twice already and the third one is on its way out. Why do you make us pay so much for poorly made power cables, please make it so you can replace just the cord that would save everyone the frustration of having to pay what now $90 for a new one ( every time I have bought one its increased in price by $10 or more) I love my computer and have had it for 7 years now so make a power cable that will las just as long or even 4 years or something along those lines.

    Not impressed.

    No?

    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.
