✔SALE: 2% OFF Apple 45W MagSafe 2 Power Adapter for MacBook Air MD592LL/A Newest Version... 3.9 out of 5 stars CONSUMER REVIEWS(22) The 45W MagSafe 2 Power Adapter features a magnetic DC connector so if someone should trip over it, the cord disconnects harmlessly and your MacBook Pro stays put safely. It also 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 lights up; an amber light lets you know that your notebook 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 you 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.

Description Use an extra adapter for home or work. The Apple 45W MagSafe 2 Power Adapter is made specifically for your MacBook Air. It's held in place magnetically, so if someone should trip over it, the cord disconnects harmlessly and your notebook stays put safely. Features This was not obvious because they LOOK the same. If you have two different Macs and have two power cords, you may want to mark which one is 45 and which is 60. Because the end looks the same, I didn't know that my Air and my Pro have different power. I put a piece of tape on one so I don't get the wrong one. I'm really not sure how Apple is calling this an "improvement" over the Magsafe 1, but they are calling it just that. In my opinion, when Apple went from the white t-style plastic Magsafe to the tubular metal design, it was a great improvement, making it harder to accidentally knock off.I purchased the new MacBook Air 11" in June 2012, and it came with one of these adaptors. I always carry a second, so I bought an additional from Amazon. My initial impression was "why in the world the change?!?!" ... and I continue that feeling. The old adaptor feels more secure, more solidly built, and overall a better quality part. This new adaptor pops off with a lot less force than previous Magsafe iterations.They say they redesigned it to make it more sleek for Apple's new slim Macbook Pro, but that makes no sense as the Macbook Air this year and last were much thinner than the MBP, and the old Magsafe worked just fine. My guess is they went to the new design which... If you're happy with the one that came with your MacBook Air, this is a duplicate of it. Works just fine.
