Apple 85W MagSafe Power Adapter (for 15- and 17-inch MacBook Pro)

  • Overview

    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 macs no doubt about it - but the 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.

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 working after almost 10 years...

      A late review but a testament to great Apple design that even after almost 10 years - the power supply, and the MacBook pro that it powers are still working. On A late review but a testament to great Apple design that even after almost 10 years - the power supply, and the MacBook pro that it powers are still working. One of the clips are broken but that's expected after so many years in service (and was my fault for putting something heavy on it! Here's to the next 10 years of use!

      Rubbish cables, aren't they?

      As a sound engineer and professional performing musician, I travel a lot with a lot of cables. I have instrument cables and power supplies that have toured all As a sound engineer and professional performing musician, I travel a lot with a lot of cables. I have instrument cables and power supplies that have toured all over the UK and Europe with me since 1998. Yes, instrument cables that are more than 20 years old... and in perfect working order. I have two Magsafe Macbook adapters. One never travels, but just has the connector available to plug the Macbook into on the desk. Never gets pulled, twisted, tangled, trodden on... unlike those cables I mentioned above. I'm on my THIRD home adapter since 2013. The sheathing splits, tears, and finally disintegrates completely. I've tried preserving one a bit longer by using shrink-wrap over the first tiny split. All that did was make it split where the shrink-wrap ends instead. The travelling adapter is carefully transported in a metal laptop case, loosely coiled in a bag. It will last less than a year before there are multiple splits in the sheathing. Total and utter RUBBISH for a professional product. There is NO excuse for Apple's adapters and cables being so poor when my other, far cheaper adapters and cables last twenty years. I'm sick of spending £80 over and over again.
