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.

  • What a piece of ... shameful product (euphemistically speaking)

    1.0 out of 5 stars

    I bought 2 adapters so far and I am about to buy a third one because of the cable shielding breaking (close to the connector). It I bought 2 adapters so far and I am about to buy a third one because of the cable shielding breaking (close to the connector). It is totally unacceptable that I would have to buy a new adapter every year because the cable breaking (and this is NOT because of heavy use or abuse). Apple's business model when it comes to these kind of accessories (e.g. cables in particular) is shameful ! Their choice of materials leave MUCH to desire as it is by far the least durable among the different brand cables I own. I may be better off buying a much cheaper adapter and made out of much better materials than this piece of .. shameful product. NO, the Design is NOT everything, Apple! Durability is ALSO important! I'm glad to see i'm not among the few giving this product the lowest review.

  • This charger is a complete and utter joke...a failure for Apple

    I'm on my 5 charger...one a year since I bought my 15" Macbook Pro in 2009. Truly disappointed in the quality of this charger. The I'm on my 5 charger...one a year since I bought my 15" Macbook Pro in 2009. Truly disappointed in the quality of this charger. The outer covering starts to deteriorate as the warranty approaches. How in the world can a company like APPLE that makes such high quality products make such a low quality charger? I have bought disposable laptops made by HP that have cords which are still working 10 years later.

    APPLE better wake up and start taking care of their customers or they will start to lose market share. People won't continue to pay exorbitant prices for low quality products for very long.

    Is anyone at APPLE monitoring the comments on their own online store?

    With more than 1300 and all of them saying the same thing, either they aren't or they don't care...either one is a major problem.

    Someone needs to wake up and realize that when people spend more than $2k for a laptop they want the little stuff to perform just as well as the big stuff.

    I love Apple products, but they have totally failed when it comes to this cord. We have had our computer 4 1/2 years and it is do I love Apple products, but they have totally failed when it comes to this cord. We have had our computer 4 1/2 years and it is doing great, but we are on our 3rd cord. It has a one year warranty, but lasts about 15 months and then just falls apart.

    I always encourage friends and family to buy Apple, but this power cord is definitely a disappointment. I am shocked at its poor quality. This is not up to the normal Apple standards. I am frustrated that Apple has done nothing to remedy this problem.
