Apple 45W MagSafe Power Adapter for MacBook Air

  • 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.

      4 months old, already failing!

      I'm a new Apple person, love the MacBook Air! But the power supply is already intermittent. It is under warranty, but they will not pay me for the half-day I wi I'm a new Apple person, love the MacBook Air! But the power supply is already intermittent. 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!

      Worst Adapter Ever

      I am now on my third adapter for my Macbook Air 2011. The laptop is going strong and I love it, but my two previous adapters failed because the wire that insert I am now on my third adapter for my Macbook Air 2011. The laptop is going strong and I love it, but my two previous adapters failed because the wire that inserts into the body of the adapter rips apart due to usual wear and tear. They fall apart every 2.5 years and that drives me nuts. OBVIOUSLY. It's not worth buying a new laptop just because the adapter is a P of S, but paying the full price of $80.00 for this accessory item six years from the date of purchase is ridiculous. What a rip off.

      Designed to fail, expensive to replace

      Like so many other people, the cord for my original charger frayed where it connects to the laptop, even though it didn't have a hard life. Apple could have des Like so many other people, the cord for my original charger frayed where it connects to the laptop, even though it didn't have a hard life. Apple could have designed it so that it had some additional reinforcement at this failure point, but I guess nothing trumps aesthetics. Apple could have also designed it so that only the cord needs replacing in the event of the cord failing, but no, the entire charger needs replacing.
