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!

      Junk cable

      Apple really fleecing their loyal customers here. My charger has gone kaput, AGAIN. This one only lasted a few months – without any undue strain or rough use. T Apple really fleecing their loyal customers here. My charger has gone kaput, AGAIN. This one only lasted a few months – without any undue strain or rough use. This is a terrible waste, and entirely out of sync with Apple's supposed 'green' initiatives. Unimpressed.

      How many will I own in my life

      Apple, seriously sort this out, it's a joke. I've had 3 Mac's, i've had at least 6 chargers, it's getting old. I'd pay the money if it was actually quality Apple, seriously sort this out, it's a joke. I've had 3 Mac's, i've had at least 6 chargers, it's getting old. I'd pay the money if it was actually quality I was paying for. I always like official products, I don't want to charge with anything else, but I don't know what else I can do, at this rate I should make a fund for chargers and save every month for the inevitable new one that's always round the corner. Also with many apple registered products, I still get the no blame you hold on this design fault and told to get a new one, well it's a bit embarrassing that this is rated 1 star from hundreds, maybe thousands of reviews isn't it?
