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

      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!

      works as intended

      One of them was broken like the other reviewers indicated but when I used 2 adaptors one for home and one for work, I have been using it for the last 2 years wi One of them was broken like the other reviewers indicated but when I used 2 adaptors one for home and one for work, I have been using it for the last 2 years without any breakage in the cable. I love the magnetic capability, it is softer than the first itreration, which saved my laprop many times. Thus, I disagree with the other reviewers in this respect. I dis not like the 90 degree version since that was dragging the laptop and laptop could fell to the ground, I had this issue several times. Last, I believe this is much better design than usb-c based too. What can be improved: well, the end cable does not have to be this thin, then all the problem will go away, people do not have to wrap the cable but add a "taper-based" cable holder as other PC companies like Lenovo. I think Apple can improve many laptop items by checking Lenovo site and testing them like best keyboards. Eliminate this "thin" madness, then everything will be ok.

      Always detaches, cable is frayed, billion dollar company still sells faulty power adapter to customers for $85 for a weak wire problem. Very sad.

Company is too big to care about the small customer issues.

      Afraid it will start a fire

      This charger gets so incredibly hot. I can't even leave it on my couch because it leaves marks from how hot it gets. It frays like crazy. The entire end of the This charger gets so incredibly hot. I can't even leave it on my couch because it leaves marks from how hot it gets. It frays like crazy. The entire end of the cord looks like a dog chewed through it. I'm afraid it's going to catch my house on fire - especially because I can't leave it on the couch or it leaves burn marks, so I have to put it on a blanket to protect the couch. I'm buying another one, but I'm sure the same thing's going to happen. I'm only replacing it because I feel like I shouldn't have fraying cords on a product that gets incredibly hot now that I've got a baby. I'm sure it will burn him one day.
