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

Get help buying. or call 0800 048 0408.
  • 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!

      Second one to fail, no matter how well I look after it.

      After 18 months my second charger has split where the thin cable enters the converter. I couldn't have handled it any more carefully than I do, well aware that After 18 months my second charger has split where the thin cable enters the converter. I couldn't have handled it any more carefully than I do, well aware that they might as well be made out of jelly. The previous one lasted 4 years so it seems they're getting even worse, not better. Come on Apple, look at the reviews on your cables - they're all rubbish. Do something about it!

      Same old story

      Absolute disgrace. I've owned one MacBook Pro and really love it, but now had two MagSafe cables fail in exactly the same place - They always break at the end w Absolute disgrace. I've owned one MacBook Pro and really love it, but now had two MagSafe cables fail in exactly the same place - They always break at the end where the cable joins the connector. And £70 for a new one?! It's a total scam really. On the last one I bought I managed to extend the life of the cable a bit more by wrapping insulation tape around the cable. Somehow it STILL seemed to break. I'll be trying the cheaper knock-offs on Amazon now. I can buy three of them for the same price!

      Yet another one!

      I love these supplies so much that I just can’t stop buying them. Lucky for me they only last about 1 year! I have lost track of how many of these supplies I love these supplies so much that I just can’t stop buying them. Lucky for me they only last about 1 year! I have lost track of how many of these supplies have died on me, the wire always breaks just before the MagSafe connector. My family has 3 MacBooks that use MagSafe 1, and one MacBook that uses MagSafe 2. Maybe Apple should do some sort of special offer, maybe buy two get one free, or get one free after buying five. My 2011 MacBook Pro is still going strong, but I have spent a fortune on new supplies for it.
