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; 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.

    Redesigned specifically for MacBook Air, the adapter is the perfect traveling companion. It 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 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 will spend going to the Apple store to get something that should last longer than the computer!

      poor quality of original product purchased a few years ago

      Rubber covering of the wiring is poor quality and peels open for no reason. Maybe they should wrap the item in electrical tape. Won't buy another apple product Rubber covering of the wiring is poor quality and peels open for no reason. Maybe they should wrap the item in electrical tape. Won't buy another apple product.

      Very expensive faulty product

      Absolutely ridiculous price for a faulty product. Apple appears to be ignoring the problem based on all the negative reviews for this product. Charger cord s Absolutely ridiculous price for a faulty product. Apple appears to be ignoring the problem based on all the negative reviews for this product. Charger cord started only working intermittently then the cord fraying at the connector which is a safety concern. Obviously you have no choice but to replace it and then pay the insulting $100 for the same faulty cord. This issue has been so frustrating that I will not be replacing my computer with another Apple product. Shame on you Apple you know this is an issue! Paying approximately 10% of the cost of the computer for a faulty power cord is stupid.

      Too low quality for $80 (eighty bucks!)

      Using it for about 5 years EXTREMELY GENTLY! Had to fix cord few times due to isolation just falling off (PVC free, sigh). Like any of Apple cords.. Just rece Using it for about 5 years EXTREMELY GENTLY! Had to fix cord few times due to isolation just falling off (PVC free, sigh). Like any of Apple cords.. Just recently it was burned and switched off electricity in the house. I'm an engineer, so decided to look inside for what happened. After disassembly I found a bad wiring that made a short circuit and burned out few components. Seems like an assembly issue, because components are ok overall. Adapter is made by LiteOn. I'm really disappointed with the quality for the price. Though computer itself is really a state of the art inside...
