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.

I bought this to replace my old adapter. The old one had fallen apart on the piece magnetic piece that connects to the computer. I heard that ALL the adapters break at some point under one and a half years. Apple must sure be making a killing on these since they are friggin $80! So far this new one has held up and I hope I won't have to replace it in the near future again. We'll see.

The power adapter does not work because Emagic did not include a crucial "prong"! One month later I am still waiting for word from this company.

I had to return this to the local Apple store after a year of use as the cord cracked near it's entrance to the brick. They did give me a new one without charge and said that this has happened a lot. If you travel a lot do not wind it around the wings that fold out as you will wear out the cord at the insertion.

[If you'd like to save some money with little risk, my experience with picking up a refurb (from the seller "macpoweradapter") was quite satisfying. it appears that these people know how convert the Mac Adapter's fatal flaw (the tearing or shorting out of the wire) into a mere flesh wound, restoring the adapter to near-mint condition. While there are no small number of Apple purists, who believe it necessary to spend over $30, for example, on a rubber case for their iTouch, I've found as good if not better on Amazon for under five bucks. The price discrepancies for the adapter are not so dramatic but are nonetheless not inconsiderable.]
Despite the exorbitant price, over time this Apple product pays for itself. Whereas formerly I would go through several per year, the "break-away" magsafe design is a money saver (not to mention lifesaver should you be down to a single power adapter and can scarce afford a broken wire). However, it tends to come loose more frequently than the comparable adapter for a regular MacBook, aborting projects while I'm using the computer in safe mode. I wish the magnetic attraction were a bit stronger.
But the above is basically the price paid for addiction to a Mac Air. The receptacle faces slightly downward, at a 45 degree rather than a 90 degree angle on the computer's left side. Given the thinness of the base, or bottom shell, I understand the need for the slant but wish it were on the top rather than bottom side, which no doubt would require some clever re-engineering (to maintain the computer's wafer-thin profile). Another solution of sorts would be improved battery life, so that a user could depend on a good 4 hours or more after each charge, thereby obviating the need for constant power connection (admittedly I run my screen bright, reducing battery life to a scant 90 minutes).
When all is said and done, it's ust another trade-off for a Mac Air--perhaps even contributing to the strange allure of this machine to those of us who are devoted to it. (Mine is even the solid state model before the huge Apple price reduction. Now if only the attraction of the plug to its magnetic base were as strong as my attraction to this machine...)

I needed a second AC adapter for my MacBook Air for when I bring it to work. This adapter works perfectly. Not complaints.
