Apple 45W MagSafe 2 Power Adapter for MacBook Air

Get help buying. or call 800-908-988.
  • Overview

    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 lead is provided with the adapter for maximum lead length, while the AC wall adapter (also provided) gives you an even easier and more compact way to travel.

    Designed to be the perfect travelling companion, the adapter has a clever design that 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.

      Poor Product

      I've had Macs for over 30 years. By far, the most badly designed accessory for any Macbook or Mac Air or Mac Pro is the AC adapter. No matter how careful you ar I've had Macs for over 30 years. By far, the most badly designed accessory for any Macbook or Mac Air or Mac Pro is the AC adapter. No matter how careful you are, the adapter breaks and shorts out long before it should; it's the Achilles heel of Apple products. At this writing, my early 2014 Macbook Air is like new, but the AC adapter just shorted out. Please, Apple, there's no reason for this.

      Charger broke within 4 months

      After transporting my charger in my backpack, I was surprised to have found the cord to be frayed. Looks like a lot of people are having quality issues as well.

      Make some changes, please!

      I love my apple products. I've used MacBooks for the past 12 years. Apple... Come on! You see all these terrible reviews! It's time to do something about it I love my apple products. I've used MacBooks for the past 12 years. Apple... Come on! You see all these terrible reviews! It's time to do something about it. I have bought three MagSafes for this laptop this year. I take good care of my electronics. I am particularly careful with my adapters because I have had to replace them so many times. Nevertheless, they randomly stop working for no apparent reason. Please correct this problem and design a more resilient adapter. Your loyal customers--such as myself--deserve better quality, especially for the price! When you decide to design a new adapter, please pass it along to me for FREE so I can test it.
