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; 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 cord is provided with the adapter for maximum cord length, while the AC wall adapter (also provided) gives users 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 15- or 17-inch MacBook Pro.

Better, but still not good engineering
I thought the magnetic connection would solve the problem with my previous Powerbook cord fraying. It didn't. 18 months, and I'm h aving to wiggle the cord around to get power. Of course, Apple will sell me another one for $79, when my problem is that $1 worth of wire broke.
Here's an idea: why not make the portion of the cable that attaches to the transformer detachable? Then when the connector frays, as it inevitably will, you could buy a $10 cord instead of paying $79 for the whole power adapter. But I guess that would eliminate a big source of profit for Apple. …

Yes for Unibody, No for older MBP's
Own Early 2008 MBP and Late 2009 MBP.
Works on the unibody, does not on my early 2008.
The port on the new MacBooks are smaller and more shallow, this charger reflects this change and will not make contact with older ports found on non-unibody.
Buyer beware, save yourself the hassle and find an 'I" MagSafe charger if you have a non-unibody. …

Dear Apple - stop being stupid. For such a great engineering company, why can't you get the obvious things fixed. These cords fray at the connector. ALL of them do. Sometimes at the power brick, sometimes at the Mac end. Then I have to go spend 80 bucks for another adapter - when all I really need is the cord. So do the right thing, and put a MagSafe connector on BOTH ends of the cord, and a MagSafe jack on the side of the power brick just like the one on the side of the computer. Then, I could (1) disconnect the cord completely from the adapter when it's in my bag, and not have to worry about the cord getting bent and broken where it connects to the power brick, (2) could have my choice of cord lenghts - maybe a short one for my desk and a long one when I travel, and (3) I could replace JUST THE CORD if it got damaged or worn, for something like 5 or 6 bucks instead of 80. What do you think? Would it be so hard to do? …

I have thoroughly enjoyed my macbook -- have had it for years. I love the computer, but I absolutely loathe the power cord. I trea t the cord well, not bending/smashing it, yet it continues to break down on me. This on its own is frustrating, but what makes the whole thing intolerable is the fact that it costs $80 to purchase another cord. This may not be a huge issue for some, but for me it is. Shelling out $80 on a regular basis is atrocious and is not what I would expect from a company like Apple.
When the time comes, I will likely not be purchasing another Mac simply because of my frustration with the power cord. Some may think this is a silly reason, but I have had enough. …

My old noname laptop PC now is 7 years old, sent to retirement on countryside house, where it is good enough for browsing and emai ls. All those 6 years of hell-like work on table, in metro, in office, in caffee, on my knees its proud noname charger is still flawlessly working. The price was around 600$ (noname PC + noname charger). Mac is better, I have heard. Mac is the most and only reliable. Well, I like my MBP. The other story is with charger brick - that is junk. And price? 1800$.. Plus every year 80$ for a sh... brick proudly called "charger"… Well.. I can buy three noname PC's with their chargers, that would not ….. me off… …

Yes you can however, it is not recommended since your MacBook Pro would never charge fully as the in put power is too low (in some applications) where the battery would always need to supply the remaining 25W. For charging it is ok sometimes, but you should buy the 85W power adapter since your computer was made to operate with it. The 85W would also charge faster than 60W.
Hope this helps …

Does anyone know if all of the three available Magsafe adapters - 85W, 60W and 45W - are the same physical size?

All three are different sizes, and obviously the higher the wattage, the larger the adapter. I freq uently swap between all three (I own 3 laptops - 11", 13" 15"). Using a 45W on the 15" results in a slower charge, but it still charges. With the higher wattage chargers, they can be used on a lower need laptop with no issue at all. The laptop just draws what it needs. …
