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

  • 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!

      2014 MacPro 15-inch

      Mine is connected to a Landing Zone docking station, and I haven't had any problems with it. Maybe as there haven't been any connect-disconnects.

      Terrible

      Longtime Apple loyalist but this cord is awful. Frayed after about six months of very careful use at the spot where the small diameter cord enters the box.

      Got a whole 18 months before the cord frayed at the magsafe connector

      I can't believe that this cord fraying thing is still an issue after so long. The cord is fraying badly after 18 months--which sounds like I'm getting better u I can't believe that this cord fraying thing is still an issue after so long. The cord is fraying badly after 18 months--which sounds like I'm getting better use out of mine than some others posting here. That's just sad that Apple can't seem to address this issue. I guess I'll go looking for clones that do it better. The power supply itself is fine--I just need a new cable. Apple, can we please fix this obvious flaw? Please?? It's not like you don't have lots of witnesses here or anything. We'd all be happy to shake our frayed cables at you if you need the motivation!
