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!

      'RUBBERISED CASING' OF CABLING BROKE DOWN & PEELED OFF ON 2 REPLACEMENTS!!!

      In common with others ... I would first state that: I LOVE my APPLE products and have done since 'going Apple' in the mid 1980s ... HOWEVER: whilst the MagSafe In common with others ... I would first state that: I LOVE my APPLE products and have done since 'going Apple' in the mid 1980s ... HOWEVER: whilst the MagSafe Power Adapters are a great improvement with the 'magnetised' little square connection to the MacBook itself ......... there would now seem to be an issue with the tendency of the wiring to 'coil in on itself' and the effect of heat .. or time ... or SOMEthing on the 'rubberised??' casing: because I have had to replace twice now because the casing has become discoloured and then disintegrated ... revealing the inner wiring ... and rendering it (them) unsafe and unusable :( It would be helpful if this problem would be addressed ... please ...... lovely people at Apple! (and as others point out replacement means replacing the WHOLE unit ... to wastage of un-necessary resources AND unnecessarily expensive replacement ..... it would be appreciated if you would address this matter too, please, Apple)

      Dreadful product. Overheats, cable frays, arguably dangerous.

      It pains me to write this because I Iove my Macbook Pro, I think it's a spectacularly elegant and functional piece of equipment, it's just that the power supply It pains me to write this because I Iove my Macbook Pro, I think it's a spectacularly elegant and functional piece of equipment, it's just that the power supply is a very long way from the same standard. These supplies are arguably Apple's worst products. Must make a fortune on them, because they're exorbitantly priced and clearly designed to be as un-fixable as possible and to fail very quickly. In warm weather, if laid flat on a carpet then they get *very* hot, suggesting some rather marginal thermal management, but that's really the least of their problems. The co-ax cable from the charger to the computer is sleeved in a material that rapidly frays at both ends, the last one I had felt like a silicone rubber that's been used past its sell-by date, stiff and brittle (And yes, it was a genuine Apple one, unless they're selling knock-offs over the counter in Apple stores) - like many others, I'm now about to have to buy my third for the same laptop - admittedly, the latest one finally died when I dropped it, but were I less adept at repairing these things it would have died ages ago - I've had to re-solder the lead at both ends (it's not easy to dismantle the magsafe end, but with the 90 degree metal sleeved ones it can be done) and I had to remove a frayed section that was arcing, a real fire hazard. I routinely have to replace the strain relief at both ends of the coax, usually within a few months of purchase - I've taken to building a strain relief at the "brick" end that has the cable exiting towards one of the fold-out lugs, so it doesn't get the 90 degree kink in it, but the other end always frays too. The mains lead sleeve always works its way out of the strain relief at the brick end, too. On the plus side, with these power supplies I think Apple have single-handedly created a market for that silicone rubber putty "sugru" stuff... I'm not heavy on my gear; I have Dell power supplies with similar diameter cables that are still absolutely fine after many years, I've never had an Apple one last as much as a year without needing some kind of (difficult) repair. Tempted by the aftermarket ones, as I'm fed up with handing sixty quid a time to Apple for something that we all know is no good, but, though the cables are unlikely to be worse, I have my doubts about the electronics in the knock-offs.
