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

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!

      Extremely Disappointed...

I love t I'll preface this by mentioning that I've been a Mac user for 25 years. The thing I love most about Apple products has (until now) been the durability. I love that my three iPhones I've had over the years have each lasted 4+ years; it's nice to trust a product will last when you're investing good money into it. My iMac desktop from 2001 still works great, but it didn't have wifi connectivity technology, so that is the only reason I made an upgrade to my first MacBook Pro laptop. That laptop still works, but I upgraded to my current MacBook Pro after seven great years of everyday use on my first one. I LOVE my current MacBook Pro! It is reliable and works great for daily writing and graphic design use. But, I digress.... Anyway, for the first time in two and a half decades, I am extremely disappointed with an Apple product! The design and quality (or lack thereof) of this charger is upsetting and not what I've come to expect as a longtime daily user of Apple products. I take excellent care of my computer and accessories, but this is now the SECOND 85W MagSafe2 Power Adapter that has gone bad already since upgrading to this computer. I never had this issue with my previous L-shaped charger for my old MacBook Pro laptop. Now I spend thousands on a wonderful new computer, and I'm spending $80 per year on replacement chargers. That is ridiculous is you ask me. I'm not sure if it's just what the skinny part of the cord is made out of or what, but it gets kind of brittle and starts to fray way too easily. Now I have exposed copper at various places along this charger, so I have to shovel out another $80 to replace it. I am just getting frustrated because I know it will happen again with the next one.

      One for each year?!?!

The magnet holds and sticks but the charger light indicator quits after 5 seconds and only to check it has stopped charging. I have to either have it pushed against something that can keep tight or hold it to charge. What’s annoying is the charger comes with this extra long power adaptor extension which I hardly use so now I have three in very good condition sitting in my cabinet...for what?!?!! Why create such waste?!?! Someone tell me where to donate them and I’ll pass them on.

      Breaks and Unplugs too easily

Within 3 months of getting my adapter (which I was wrapping around the prongs on the block), the wires frayed and I had to replace it. Since that method didn't work, on the new one I tried wrapping with the over/under technique I use on audio cables that is supposed to prevent damage. That cord only lasted about 6 months. There needs to be a better, stronger design that doesn't break. It's also annoying that you can only charge on a desk. It comes unplugged way too easily when it is on my lap, which kind of defeats the purpose of a LAPtop.
