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!

      Worst product of Apple.

      I'm in love with all the products of Apple, but this one is really horrible. Every year I have to buy 2 new chargers for my macbook.

      Worthless

You would t I've had 2 Macbooks within the past 10 years. Both chargers for both Macs were horrible. They fray at the end after just a few months of being used. You would think that Apple would spend a little of their R&D funds on making a better charger. It's ridiculous that this has not been fixed yet. All of the people who gave it 5 stars is questionable because there are more negative remarks than positive on this one. And everyone who says that we're not treating it right, don't know us. I unplug my charger by tipping it out of the port (I don't twist it out). I pull the plug out of the wall by the plug (not by the cord). I don't wrap the cord around the useless/meaningless wings on the block (I wrap it loosely around my hand. And even if I did wrap it around the wings of the block, Apple designed it to be used that way, so they should fix the horrible thin cable problems that have plagued these chargers for years. It's time that Apple thinks more about its customers than its bottom line. We've spent too much on this company for them to not care about those of us who have problems with their cables. If it's not fixed soon...I'll have to go with a different brand with my next laptop when this one dies out.

      Burned out

      good thing i reached out before the mother board burned out completely. the adapter was a little over 2 yrs old. I had to clean the contact area with a toothbru good thing i reached out before the mother board burned out completely. the adapter was a little over 2 yrs old. I had to clean the contact area with a toothbrush to remove soot most likely this was getting too hot while charging. though this did not last long before i had to replace the charger. for a 1700 comp with not so good quality accessories costing quit a few dollars to replace, not sure apple is listening to its customers.
