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

Magnet not Strong Enough
I have had all versions of MagSafe. The Original T, The L, and now MagSafe 2 with my MBP Retina display. I am a fan of the T des I have had all versions of MagSafe. 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. …

2014 macbook air magnetic power source
I have had a macbook air for the past 4 years and love it, but as it got older and slowed down it was time for a new one. Many ni I have had a macbook air for the past 4 years and love it, but as it got older and slowed down it was time for a new one. Many nice upgrades like the lit keyboard, but man,every time I sneeze or move 4 mm, it disconnects.....I sure hope Apple has a fix for this and will be supplying them to all their apple supporters, users and share holders at NO cost. The old one was fine and did the job fine for 4 years. This is my first night using the new one frankly, sitting relatively motionless for 3 hours, it has come out 10 plus times. I am ready to tear my hair out. Like one of the other comments stated, now that the Steve Jobs is no longer with us, I pray this is not a pre curser to what down the pipe. Apple has become the wealthiest company in the world for a few reasons, incredibly forward thinking designs and excellent products both in appearance and functionality, but equally as important, the cult following of people who will spend 3 times more than the PC competitor as a result....It will hurt apple in the future if these extremely easy problems are fixed in production rather than getting a litany of complaints and concerns from your customers, who in all reality, are one of the main reasons apple is where apple is! I hope we see a fix soon, or I will simply return the 16 new units I bought for myself and my star within a week and go back to our old devices. Thank you for listening. …

Horrrible, horrible product
I am about to buy my 3rd of these in the last 2 years. In both cases, the cord started to fray at the base and then burned out so I am about to buy my 3rd of these in the last 2 years. In both cases, the cord started to fray at the base and then burned out so hot that it actually started smoking. An unacceptable, completely malfunctioning product. Good thing I have to buy another now. …

wire frays and brakes
The wire frays and breaks. It will need replacing with a year or two. Apple should have done better.
