Apple 85W MagSafe 2 Power Adapter (for MacBook Pro with Retina display)

Need some help?
  • Overview

    The 85W MagSafe 2 Power Adapter features a magnetic DC connector so if someone should trip over it, the cord disconnects harmlessly and your MacBook Pro stays put safely. It also 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 lights up; an amber light lets you know that your notebook 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 you 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 MacBook Pro with Retina display.

      Sad, unfortunate design flaw

      The plug has a serious design flaw that causes it to disengage far too easily from the socket. The plug and wire extent out about 3/4" making it a long lever. The plug has a serious design flaw that causes it to disengage far too easily from the socket. The plug and wire extent out about 3/4" making it a long lever. The magnet is quite strong, and pulling the plug out straight takes quite a bit of force. Tap the wire or plug up or down however, and it comes right out. Such is the power of leverage. It works fine on a desk, but on your lap it can be a challenge to keep the plug in. This should be, and hopefully will be, redesigned in the next revision. The lever needs to be shortened. The L connector design helps by removing the wire, but its not absolutely necessary. The plug itself is more important as it does not flex and is too long, Something shorter and fatter would be more effective.

      Horribly Weak Connection

The entir After spending $2,000+ on a rMBP I am HORRIFIED at how annoying this connector is. The L-Shaped connector on my MBA was excellent but this is so weak. The entire point of having a laptop is to use it on my lap, on the couch, in bed, or any other place I desire... but this power adapter does not allow for that as it comes loose at the slightest nudge. It annoys me to the point of searching the internet for "tips" on how to keep the thing in there. (to no avail)... which led me here - where I just am going to repeat the cries of all the others that HATE THIS ADAPTER.

      T shape - bad design for the power adapter

      As others have commented before, the power adapter keeps falling off. It's not that the magnet is week, but the design itself is faulty. Even the smallest f As others have commented before, the power adapter keeps falling off. It's not that the magnet is week, but the design itself is faulty. Even the smallest force on the T-shaped connector acts perpendicularly, which easily hooks the connector off. The previous L-shape may have been a better design. Last but not the least, I wanted to buy a spare adapter for home but $79 (+tax) for this useless adapter feels like a total ripoff!

      Is my hand on fire?

The little magnetic c Today I absentmindedly rested my hand high on my laptop when all of a sudden it felt like I was touching a stove top. It was the charger!! The little magnetic clip piece is so hot I can't touch it. Naturally, I turn to the all knowing internet. And there I found I was among many other unfortunates in love with a Mac, yet cursed by a necessity that is dysfunctional, cheap, and trying to mutilate my hand with volcanic force heat. So here I am, digging through all these 1 star reviews of this terrible charger. Thinking to myself... my laptop is from the dark ages of 2015...perhaps it is time to upgrade? NO. This is what they want...So instead of paying $700 plus trade in value for my perfectly good laptop worth a million dollars in 2015...I will sadly, begrudgingly, add this worthless, evil charger to my basket. Because...I gots to. Me needs the laptop..ALIVE. WHY Apple, whyyyy...

      this charge cord is horrible

      I've had my Mac laptop since 2013 when i bought it for university. The Mac itself is fine, but the cord to charge it has been a pain in my side for forever. I a I've had my Mac laptop since 2013 when i bought it for university. The Mac itself is fine, but the cord to charge it has been a pain in my side for forever. I am on my third charge cord and the material covering the wire has split so far that I've had to resort to creating my own buffer. The first cord I had burned through my bed sheets! The second one got so bad it burned my hand, and the current one I don't find a need to replace if it keeps getting destroyed. Please fix this problem for all of us. I love my laptop but if I cant charge it I'll have to move to a different manufacturer altogether.

      Apple needs to completely redesign the chargers.

      The biggest problem is that these just don't last. between my 2 MBP15s I've been through so many I lost count. They get super hot right out of the box. I suspec The biggest problem is that these just don't last. between my 2 MBP15s I've been through so many I lost count. They get super hot right out of the box. I suspect that's the principle problem. I don't know if they need to make them bigger to space out the components or ad some kind of ventilation. I suspect the designers are just trying to be too slick.
