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

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

Product Information

  • The 85W MagSafe 2 Power Adapter features a magnetic DC connector so if someone trips over it, the lead 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 full charge. An AC lead is provided with the adapter for maximum lead length, while the AC wall adapter (also provided) gives you an even easier and more compact way to travel.

    Designed to be the perfect travelling companion, the adapter has a clever design that 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.

  • Magnet not Strong Enough

The Original T, The L, and now MagSafe 2 with my MBP Retina display. I am a fan of the T design but the magnet holding it in is way to weak. I don't know if it is because its smaller profile, but I can barely touch my laptop without the thing falling out. It is becoming extremely annoying to the point where I might need to walk around with a brand new MBP with its power cord duct taped to it! I believe the magnets are in the systems itself but please Apple come out with a revised adapter with a second set of neodymium magnets in the charging tip to counter act the problem and grab the machine tighter. I'd rather it be bulkier and work properly. I understand the point that is supposed to break away, but not by a feather landing on it! We miss Steve Jobs. I hope this isn't the type of product glitches we will have to get accustomed to now. Apple is supposed to be Apple, This isn't Apple at all.

The people who are complaining must use their equipment in very strange (inappropriate) conditions. Melting power bricks and frayed wires sound like a user-related issues. If you are careful when you wind your cable up and keep the power adapter in a sensible location, it will last you a long time. That said, as an owner of a Summer 2012 Retina MacBook Pro, I've noticed a little bit of small cracking in the rubber cable shielding near the input point on the brick. This is the point that gets the most stress, as it is where the cable is pulled to its greatest angle when winding it up for storage. It would be nice to see Apple considering the potential for this kind of wear; a stronger, more flexible support point would be useful.

    I read here about the 100% probability of the cable itself "fraying", frying, or just dying after days or less. I did want to buy one as both a backup (worst case) or as a second "charging station" in a 2nd location. But what scary reviews! I have very few complaints about travel or home use with this rMBP - a dream machine! I too wonder if its evil could be just a tad "exaggerated". Of course, I am sorry for those who had to spend $80 repeatedly, in their view for "normal use".

    I examined my one power cable, which I've used every day in one way or another, charging, plugged-in desktop, or laptop. Yes, I've had the plug pop up (sometimes) when I move with it, or if I'm walking from where the plug is to a nearby desk in a hotel, wherever/whatever. For about 1 1/2 years now I have stuffed the power cords and adaptors into a bag, packed it all in a carry-on or saddle bag, on puddle-jumper airplanes, and neatly wound and displayed in travel bags for customs, TSA etc.

    Conclusion: What I can see is some slight fraying - that's the right word - directly where the computer-to-adaptor-block wire connects. I'm fortunate maybe (given all the reports), because now I'm aware, and I've just (nervously) gotten a backup should I need one. I haven't needed one, though now I put a tiny wind of electrical tape just at that joint, as I did with that skinny cable from iPhone to Mac (same issue).

    The way my "fraying" happened is from winding the cable around itself (one of the touted features, so- C'mon Apple, get it better!) , same as I've done with the iPhone and connector to a Mac. The other thing I conclude is the only way this Magsafe2 comes out often, is if there's tension (or a tug), right? If you take the power block and put it near the Macbook (which makes sense), if you give the cord lots of slack, there IS enough magnet strength to hold it in place. I haven't found anything to convince me otherwise, of any inherent net "flaw" in the design. I think MacBook users are often "power users" or road warriors who don't take time to think about things like connectors. Connections, yes.

    I am sure, as they say "your mileage will vary", but I think depending on your lifestyle and how you attend to your adaptors, this is not something which is guaranteed to break 3 times a year, at $80 a pop. If so, I'd be singing with the chorus. But I'm living proof, it sometimes lasts more than a year without problem, even actively used. I'm thinking it's how you strain the wire joints. Like people.

    My charger cable came apart right where the small cable begins. Based on numerous other reviews, this is a common occurrence. I My charger cable came apart right where the small cable begins. Based on numerous other reviews, this is a common occurrence. I paid nearly $4k for the computer, you'd think the cable could hold up to light daily use. Thanks APPLE!

    Would give it no stars if possible.
