Apple 85W MagSafe Power Adaptor (for 15- and 17-inch MacBook Pro)
Apple 85W MagSafe Power Adaptor (for 15- and 17-inch MacBook Pro)
Product Information
-
The 85 Watt MagSafe Power Adaptor 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 adaptor for maximum lead length, while the AC wall adaptor (also provided) gives users an even easier and more compact way to travel.
Designed to be the perfect travelling companion, the adaptor has a clever design that allows the DC cable to be wound neatly around itself for easy cable storage.
This power adaptor 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. …- Written by John G from Bowie

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. …- Written by Steven R from Whitby

Not compatible with older Macbook Pros
The MagSafe connector on this power adaptor does not fit older models of MacBook Pro. This newer connector is marginally smaller a nd 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! …

3rd Charger in as many years
This is the 3rd charger I've had to buy in as many years, the spindly cabling is just not fit to last and breaks even when a compu ter is barely moved. …

Chargers are problematic
I have had my MacBook Pro four years now and am on my third charger. The factory supplied charger and the second charger both had broken wires. The Genius Bar told me that it was because I was wrapping the cord too tight. I always used the ears on the charger to wrap the cord, nothing abnormal. This design flaw has cost me $160 thus far. I love my Mac but something needs to be done with the chargers. …

Mine sparked up and melted the cord!
I am so surprised to see so many people who have had the same issue with this cord.
Apple did replace the cord as it was still under the 1 year warranty. They also escalated the issue to engineering, and I am expecting a call from them to verify the issue.
This is dangerous! Mine was getting really hot for weeks and then produced a large spark which almost separated the cord completely from the base. The cabling was exposed, the plastic coating was burned. Obviously at this point the cord was useless.
I can't believe that Apple would sell such a poorly designed product. …- Written by Laura R from Markham

Does anyone know if all of the three available Magsafe adapters - 85W, 60W and 45W - are the same physical size?
- Asked by Philip D from Vancouver
- 14/02/2013
Answer
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. …
