Apple 85W MagSafe Power Adapter (for 15- and 17-inch MacBook Pro)
Apple 85W MagSafe Power Adapter (for 15- and 17-inch MacBook Pro)
The 85 Watt MagSafe Power Adapter features a magnetic DC connector that ensures your power cable will disconnect if it experiences undue strain and 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 will light up; an amber light lets you know that your portable is charging, while a green light tells you that you have a full charge. An AC lead is provided with the adapter for maximum lead length, while the AC wall adapter (also provided) gives users 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 15- or 17-inch MacBook Pro.

They kinda fixed teh second most important problem...wow great job
While its fine and dandy that they changed one end of the cord, its the other end that is most likely to malfunction. I love my ma While its fine and dandy that they changed one end of the cord, its the other end that is most likely to malfunction. I love my macs no doubt about it - but the magsafe adapters make me hate apple. The magsafe is such an expensive devise and at the same time the cord is so prone to braking off where it is connected to the charger. And then you cant just buy a new cord...you HAVE to buy a whole new charger...this is both very bad for the consumer and also for the environment. I really hope apple will soon realise that this way of milking costumers is not viable in the 21th century.
So I beg you Apple: please fix the real problem and make a magsafe with a detachable cord. …

Mac Adaptors in general
For a company that does so much so right, why let yourselves down with a sub-standard, massively over-priced essential piece of eq For a company that does so much so right, why let yourselves down with a sub-standard, massively over-priced essential piece of equipment. The rubber cord isn't working, make it high quality woven polymer cord. Reduce the price by half, you wouldn't loose money. sales volume would increase as it would stop people buying cheap copies from auction sites.
If you buy one, you have a mac so keep your loyal customers happy. Please. …

Serious design flaw magsafe cable connection to charger
I'm on my fourth charger for a 2010 mbp. The magsafe cable unravels at the connection to the charger, the cable is not strong enou I'm on my fourth charger for a 2010 mbp. The magsafe cable unravels at the connection to the charger, the cable is not strong enough and starts to unravel after about a year. I always take care of my electronics and am not using it harshly but I am on the move a lot. I had a few other brands of laptops none off which I've had to replace the charger for even once. I've tried using the clips to wrap the cable when storing but this seems to make the problem occur sooner. Apple doesn't seem to recognise this problem and does not respond even though in my own personal circle alone I know 6 people who are having the the exact same problem and the message boards are full of this problem. …

Possibly the worst thing made by Apple
The infamous Apple charging cables strike again. I'm on my THIRD Macbook Pro charger, again because of the fraying in the same exa The infamous Apple charging cables strike again. I'm on my THIRD Macbook Pro charger, again because of the fraying in the same exact points time and time again by the terribly made cable. I don't mistreat my chargers, especially after the first one frayed and broke. The brick itself is a great piece of design, and I'm happy about that part. But unfortunately that's negated by the absolutely terrible quality of the cable that renders the entire thing useless if (and when) it goes out. It doesn't help that the price of the charger is very expensive for the quality you get, and I'm continuously denied a replacement in Apple stores, even though the damage is clearly by fault of design. If Apple focused on making their cables to the same quality as everything else they make, I'm sure these reviews would be massively different. Until then, these necessary evils will continue to be hated by the masses. …
