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. …

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! …

Luckily I was there when this happened so it didn't burn the house down. I thought it was just cheep replicas we had to be worried about. Not genuine Apple products!

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) …

The white box is a built in power converter so you should be fine with plugging it in as long as you The white box is a built in power converter so you should be fine with plugging it in as long as you have the adapter that changes plug types. You can check to see if other things are converters if it has something like Input: 100-240V~1.5A 50-60Hz. This shows that an electric current of 100-240 Volts can power the converter without problem, which Spain's electricity falls in. If you cannot find this on a product (though most electronics made in about the last 5-10 years automatically convert) or if you feel you would rather side with caution you can but a converter, but only leave it plugged it when you need the power because converters burn out quickly from overheating if you leave them plugged in too long. …

Can I use an 85W magsafe power adapter to safely charge my MacBook Air?
- Asked by Bryce B from New York
If the ports of the adapter fit your macbook air, it means it is designed to be compatible with the If the ports of the adapter fit your macbook air, it means it is designed to be compatible with the air.
So answer is yes if the port fits. 85W just means that it has larger capability of supplying larger current with the same voltage when it is necessary. So when you plug 85 W power adapter into your air, it will give just enough current to the Macbook Air. Since the voltage is kept the same, it won't cause any problem. …
