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

Get help buying. or call 1-800-MY-APPLE.
  • 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!

It breaks so easily it's ridiculous. This is for a laptop that many want to bring with them every day. Try doing this and bringing this magsafe with you. I dare you. Count how many days it lasts. If it's over 100 days, you're as lucky as no other man or woman has ever been throughout the history of this earth.

      Truly Terrible Product Design

      Sure, the connector sticks out way too far and frequently disconnects under ordinary use, for example, when you place the laptop on your lap. But the absolute w Sure, the connector sticks out way too far and frequently disconnects under ordinary use, for example, when you place the laptop on your lap. But the absolute worst design failure here is the cord itself. I have never worn out a cord on any device I have ever owned... except this one. I've gone through at least seven of them. They just disintegrate, no matter how delicately you treat them. In fact, with the one I got just four months ago, I made a point to (almost) never take the cord with me. But despite being nearly stationary for its entire existence, it's actually starting to turn YELLOW and deteriorate. Seriously, Apple! Why do you stick with this fragile cord plastic? Especially when it's so high-friction that it seems to tangle itself. That's another big design fail but self-tangling seems trivial compared to self-destructing.

      TERRIBLE!

      There's another 266 reviews I can see, and this product averages a rating of 1 star. That should tell you something. I have a 2015 MacBook Pro (11,5). This i There's another 266 reviews I can see, and this product averages a rating of 1 star. That should tell you something. I have a 2015 MacBook Pro (11,5). This is my 3rd charger. First one melted the plastic inside the magnet AND the cord itself, the second one developed burned contacts inside the magnet and has damaged my MagSafe charging port on my machine (it eventually stopped working after only 4 months), and the third one - which is brand new - is sparking like mad every time I connect it to the MagSafe 2 port. Apple really needs to solve this problem badly. Really disappointed about this - after all, it's a Eur3100 piece of hardware.
