  • Overview

    The 45-Watt MagSafe Power Adapter for MacBook Air 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.

    Redesigned specifically for MacBook Air, the adapter is the perfect travelling companion. It 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 only with MacBook Air with MagSafe Power Port.

      Works Fine - BUT PRICE IS RIDICULOUS

      I've got a MacBook Air 13" (2011) that I feel is the finest travel computer for a businessman ever invented. I love this little workhorse. Also, the power ada I've got a MacBook Air 13" (2011) that I feel is the finest travel computer for a businessman ever invented. I love this little workhorse. Also, the power adapter on mine works just fine ... no problems. Instead of unplugging every time I hit the road, I thought it would be a good idea to buy a spare for my computer bag. Wrong! $79.95? Is this someone's idea of a joke? Eighty bucks for a power adapter? Sure the cell phone manufacturers have run this scam for years, refusing to standardize on a plug configurations/power ratings so that the buyer is forced to buy yet another power adapter (I've got about twenty of them sitting in a drawer). But those pieces of junk are only $20 or $30. $80? For what? I've got AppleCare, so I'll just keep on plugging in and unplugging the one adapter I have until it dies, then you can replace it for free. Really, you folks at Apple build the coolest stuff on earth, but you do need to re-think your policy of over-charging for the small stuff.

It is under warranty, but they will not pay me for the half-day I will spend going to the Apple store to get something that should last longer than the computer!

      Product is Excellent

      This is a great charger. I ordered one four years ago and the only reason I had to replace mine was because my roommate vacuumed over the head of the DC connect This is a great charger. I ordered one four years ago and the only reason I had to replace mine was because my roommate vacuumed over the head of the DC connector. Otherwise, I would have probably been able to keep it for a couple more years.

It appears that one crimp or twist causes the cord to stop working, and as someone who travels a good deal, I don’t want to feel compelled to carry a backup or two. The design is just fine, but the product durability is deplorable.

      It still works after 7 years

      The only reason I deduct one star is because the design could be improved. There could be a metal base and metal flex coil protecting the ends that get the most The only reason I deduct one star is because the design could be improved. There could be a metal base and metal flex coil protecting the ends that get the most wear and tear like my inkey charging cable does. However, after 7 years my Power Adapter casing is frayed and worn so that the metal wires are exposed. I was sure this is a fire hazard so in March 2019 I went to the Apple store to buy a new replacement Power Adapter. I expect it will last as long as the original has. That is only around $11 per year for an accessory that still works with the original MacBook Air that it came with. I am very clumsy and accident prone. My devices and matching accessories have not had the kindest of care. They all still work.
