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

      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 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!

      Terrible Insulation Material, Frays in Just a Year

      I absolutely HATE the material Apple uses for their power cables' insulation. Why do they feel the need to use such a soft and easily ripped rubber? How about s I absolutely HATE the material Apple uses for their power cables' insulation. Why do they feel the need to use such a soft and easily ripped rubber? How about something that will actually last as long as the computer? Why can't the MagSafe cable itself be detachable from the power brick just like the AC-side extension cord? Maybe then I wouldn't have to spend $100 every year replacing the entire thing. But then that'd cut into Apple's profits, just like why they ditched the iPhone's microphone jack and all the useful ports on the MacBook Pro in favor of dongles. It's not like my computer gets subjected to a lot of wear and tear, it just sits in my bedroom. How a power cord self-destructs like that under such low stress conditions I have no idea other than Apple designing them to fail.

      MagSafe connector failed - just before a big meeting

      These things are the worst. Seriously deficient for a company of Apple's reputation. Shameful that they do not recall/replace these. My laptop literally stop These things are the worst. Seriously deficient for a company of Apple's reputation. Shameful that they do not recall/replace these. My laptop literally stopped charging just one day. About two hours before a big presentation, I was out of town, nowhere near a store to replace this. Luckily a guest in the hotel had one and lent it to me. Kind soul. Otherwise I would have been SoL! Apple, get your $hi# together on this. Will seriously consider a windows machine next time. B

      4 DAYS OF USE!!!!

      I got this computer and used to for 3 charging cycles before it literally quit working. The LED light doesn't come on and it will not charge my computer, or any I got this computer and used to for 3 charging cycles before it literally quit working. The LED light doesn't come on and it will not charge my computer, or anyone else's apple computer I have tried it on. This is asinine!
