Product Information

  • 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 Air 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.

    Compatible only with MacBook Air featuring MagSafe 2 power port.

    Quite careful with my equipment. This one simply stopped working under no significant stress conditions. Quality control alert.

When I saw the reviews I thought they were joking. I feel like sending the entire laptop back because of the adapter. It falls off for no reason and gets in the way. Apple needs to do a recall.

The new MagSafe 2 hasn't been available for that long - only since the new 2012 MBA's came out in mid-June. The new MagSafe 2's charger attachment magnet is incredibly weak and will detach at the slightest provocation. Or unhappy thought. Or suspicious look. This product is terrible and Apple should fix this as soon as possible.

  • MagSafe 2 - HORRIBLE- You'll need to superglue it to your MBA!

    I've owned several MacBooks & never gave a 2nd thought about the power adapter until I purchased my MBA 11" & was intro ducted to I've owned several MacBooks & never gave a 2nd thought about the power adapter until I purchased my MBA 11" & was intro ducted to Apple's worst idea ever called the MagSafe 2. Oddly enough I use my little 11" MacBook Air not as a desktop but as a laptop - literally on my thighs (sarcasm intended) - The problem is the MagSafe 2 is so sensitive that if I shift - it disconnects. If I lift it up to set on an end table to go grab a cup of tea or coffee, the MagSafe 2 disconnects. If I even think about moving the computer it seems to disconnect. It's not so bad side to side (i.e. front/back) or pulled directly straight out from the MBA. However the most common flex a power cord is going to get is up/down & that's where the MagSafe 2 is at it's worst. If it even slightly senses it's going to flex up or down it disconnects. Seems the design in mind was for using the MBA on desks or library tables - i.e. flat surface. The designers forgot what laptops were designed for - LAPS & quasi mobility even when plugged into power. In the MagSafe 2's defense I've read the design flaw is actually with the magnets in the MacBook itself. They are too sensitive or too weak to keep adequate connection with the adapter made worse by the "T" design connector of the MagSafe 2.

The magnet i The adaptor that came with my mid-2012 MacBook Air is still working perfectly and I travel with it almost every day. The magnet is not as strong as the original MagSafe, but it still works fine. You can find cheaper versions of this adaptor on Amazon, but I suspect your results will vary widely from "completely disaster" to "works reasonably well".

    I've had my macbook air for almost two years now and I had to purchase a new charger yesterday. Mine got the "wrinkles" at the bas I've had my macbook air for almost two years now and I had to purchase a new charger yesterday. Mine got the "wrinkles" at the base of the cord closest to the actual charger. One day it was working fine and the next it wouldn't charge at all. I have taken very good care of the cord, never carrying it in my bookbag and never bending the cord while it was charging. After spending over $1000 on a computer you would think the charger would be better made...
