Apple 85W MagSafe Power Adapter (for 15- and 17-inch MacBook Pro)

  • Overview

    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

      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 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?

      Yes for Unibody, No for older MBP's

      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 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.

      80 bucks to replace frayed cord?

      This is the third time I've bought a replacement cord for my Macbook Pro, always for the same reason: the cord frays at the power brick because it is always get This is the third time I've bought a replacement cord for my Macbook Pro, always for the same reason: the cord frays at the power brick because it is always getting bent in order to store the cord for transport. Why can't Apple make this cord detachable, so that it can be removed from the power brick when transporting and/or replaced when frayed? This little cord has cost so much to replace.

      Hope 3rd Time Is A Charm

      It doesn't help when you're the type that tries to be careful with storing away devices properly especially with this delicate product. This will be my 3rd MagS It doesn't help when you're the type that tries to be careful with storing away devices properly especially with this delicate product. This will be my 3rd MagSafe power adapter. Somehow my Early 2008 Macbook Pro 15 outlasted the first 2 power adapters. So why am I on my third? Yes, you guessed right! IT FRAYED AGAIN! Most recently it started to sizzle and spark with the smell of burning. Now, what do you think would've happened had this been on my rug without me noticing? Design wise. The original first MagSafe power adaper pull-away design was better, no wonder the new MagSafe 2 magnet looks like the original. There were occurrences when someone tripped on this power adapter and rather than disconnecting, it tugged on my Macbook. It looks "nice" that this adapter is slim and hugs the computer but I think it "hugs" it too hard to disconnect as intended.
