Apple 45W MagSafe 2 Power Adapter for MacBook Air
Apple 45W MagSafe 2 Power Adapter for MacBook Air
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.

Only read reviews of MagSafe TWO - it's TERRIBLE!
All these reviews saying they've had no problems for over 6 months are reviews for other models. The new MagSafe 2 hasn't been ava All these reviews saying they've had no problems for over 6 months are reviews for other models. 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. …

Is It Designed To Break?

Before this happened, the charger performed adequately enough. Now, it doesn't even work because the cable snapped. It is almost as if Apple is designing its products to fail. …

Does what it's designed to do.
I have no issues with the power cord falling out if it's being forced at an angle. I'd prefer the plug do this rather than damage I have no issues with the power cord falling out if it's being forced at an angle. I'd prefer the plug do this rather than damage the components of the laptop. If it keeps falling out I simply change my position or the laptops. I've have mine for over a year with no signs of degradation regarding the cord or plug. Maybe I got the good one. I think some of the folks are being a bit too harsh on this product. …
