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!

      Old T-shape still undamaged after 10 yrs, this L one broke INSIDE THE HEAD

Brand new 2 months ago and broke inside the head in no time, it's very confusing and you think it's your laptop but it isn't, it's breaking inside the head, HERE'S WHAT APPLE WILL NEVER TELL YOU: The cables are cheaply designed and the ends assembled by robots that can't do the math for the cheap lazy humans. One wire wraps around an insulated wire and after it's been unwrapped and re-twisted to be soldered, it's way too short and doesn't reach the (verylong) PCB in the magsafe head. The PCB is nearly twice the length of the magnetic connector so that sleek looking aluminium barrel is (as near as makes no difference) where the wire itself stops - which it really shouldn't, hence the "suicide connector" Therefore the strain relief is barely a strain relief at all, it's actually the length of ally barrel they needed in the first place to give these things a chance of never breaking (like the old T-shape they've mysteriously gone back to) It would seem deliberate - as we all know solder is not a gap filler and yet it's being used as one - and I hope there's a "snapgate" or something out of this that makes apple buck their ideas up. For anyone uncertain and ESPECIALLY APPLE: I have never broken a cable in my life, I have always been amazed I've held onto the old (dailly used) T-style magsafe 1 based on the form-over-function design and the resulting poor quality of it and I'm not surprised an L-style was my first breakage. Not that I'm gonna take responsibility for it, that's all on apple for using solder as a gap filler and not making the barrel anywhere near long enough to protect the solder joints.

      Wasteful design

      As others have said, a major design fault means the whole lot needs replacing, instead of just the lead, when it inevitably fails. About as un-green as you can As others have said, a major design fault means the whole lot needs replacing, instead of just the lead, when it inevitably fails. About as un-green as you can make a product. If Apple can get it right with USB chargers, they could have done it with this design.
