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; 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 cord is provided with the adapter for maximum cord length, while the AC wall adapter (also provided) gives users an even easier and more compact way to travel.

Designed to be the perfect traveling companion, the adapter has a clever design which 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.

    Meltdown

    Written by MM from NAPLES

    Aug 5, 2007

    My mag connector cord melted as well and became unusable. Apple stores have none available and the on=line info indicates 6 or more weeks delivery. Apple really needs to address this issue. More

    Meltdown after 9 months

    Written by JT from Grosse Pointe Park

    Aug 11, 2007

    I am and have been very protective of all parts of my MacBook Pro, but recently the junction of the MagSafe tip and the cord to the main power unit has begun to melt and fray. This has rendered my MacBook Pro nearly unusable, as I have no way to charge it.

    I hope this unit has been redesigned to safely carry the 85w of power without destroying the unit.

    AC adapter meltdown

    Written by EC from New York

    Jul 28, 2007

    Hmmm...the computer is 15 months old and exactly 13 months in use. Tender, loving care has been provided, and the adapter never leaves the house.....however, base connecting point of the AC adapter's nifty magnetic head just started to smell of melted rubber; now it is looking melted and i can see the wires inside! Sure enough it will stop working shortly! Should i buy a new one? sigh. More

    they need to reinforce this design STAT

    Written by LP from Scottsdale

    Dec 1, 2009

    I have had this same charger break on me twice now, and they are not cheap. The end that plugs into the computer WILL break and expose the wires. Does not matter how careful you are with them. I really hope they come up with a new design for this. They are lucky i gave it one star, only because i haven't had any other kind of problems with it. Again, though...This is the second charger that has broken in 1 year. More

    Apple's Worst Product Award goes to the MagSafe Power Adapter.

    Written by MC from Rancho Cordova

    Dec 1, 2009

    Beginning one month after ownership of the adapter it would occasionally not charge the computer, and after three months it failed completely.

    Apple Care replaced it; However, the new one has wires that are one by one becoming disconnected from the MagSafe connector, and they are exposed about a quarter inch now. The wire jacket is becoming loose on the adapter end as well. This all happened in five months.

    Both adapters became dangerously hot, so when I use the extender I have to make sure it's resting on something fairly heat resistance to prevent damage. This excessive heat buildup shows a poor transfer of energy. In other words you're wasting money paying the electric company for lots of heat that should have charged your computer. That's neither economically efficient or green.

    I think that $80 is an absurd price to pay for this adapter. Especially for how it performs. Apple needs to address this issue before I will recommend their computers to anyone.

    No problems with 85W MagSafe Power Adapter

    Written by RT from San Luis Obispo

    Nov 30, 2009

    I have used this power adapter with my 15" MacBook Pro for nearly 3 years now with no problems. Mostly it is used at home at my desk but I have traveled with it a number of times and it seems to have held up well. I am careful when I unplug or disconnect it from my laptop as well as when I coil the wiring cords to place it in my laptop carrying case. I have not noticed any unusual heating near the connections.
