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. …

Not compatible with older Macbook Pros

This newer connector is marginally smaller and does not fit snugly into the socket on the computer. I bought two of these at the Apple Store, Regent Street which didn't work, and I was eventually advised to buy the older part number MA938B for my January 2008 MBP. Check before you buy! …

Still faulty after all these years
My MBP is classed as vintage now but it's still going strong - although there was a hiccup with an internal connection last year. My MBP is classed as vintage now but it's still going strong - although there was a hiccup with an internal connection last year. But I am now about to get my fifth Power Adapter and every one has had the same problem. The cable breaks at the point where it enters/leaves the adapter case. There really is no way that this joint will not be put under stress/strain no matter how careful you are. It really is time that Apple made this a plug in cable at the power pack end as is just about every other laptop adapter (but with Apple's design of course) …

Poor Product Design
I am on my 4th charging cable in 3 years! The price is extortionate. If this one fails, I might start buying cheaper alternatives. I am on my 4th charging cable in 3 years! The price is extortionate.

Terrible Build Quality
Like the other reviews on here, I am about to begrudgingly buy my 3rd charger in 3 years.
The cable quality where the cord con Like the other reviews on here, I am about to begrudgingly buy my 3rd charger in 3 years.
The cable quality where the cord connects is shameful, weak and encouraged to fray by actually making use of the pull-out ears to wrap the cord around. Even if you do this loosely eventually the rubber cable shield will perish. Apple are well known for the appalling build quality of their chargers, and the ridiculous price to buy replacements, but I wonder if they are actually taking these reviews on board? I can't see how a reinforced connection would be difficult to implement. It would increase customer satisfaction immeasurably.
1-Star, but even that is generous. If you're reading this review you're probably in the same position as me. The struggle continues. Wake up, Apple. …
