Apple 45W MagSafe 2 Power Adapter for MacBook Air

Need some help?
  • 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 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.

      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.

      Not even frayed and having issues

      Reading all of these reviews I'm no longer surprised, but I've had my MacBook Air for only six months and the charger started to have issues 3mo in. I've been a Reading all of these reviews I'm no longer surprised, but I've had my MacBook Air for only six months and the charger started to have issues 3mo in. I've been able to get it back to function by the "waiting it out" game... but at this point it's stopped worked all together. No frays, no damage. If this has been an ongoing issue, Apple needs to step up and have some accountability for it already.

      What are you doing with your chargers?

The chord frayed in two places, but my computer and charger have been all over the place. The fact that it has managed to get me through so much including 3 years of me dragging it all over campus is beyond amazing as my first computer's charger barely lasted me a few months. I haven't had any issues with charging even with a frayed chord. The only reason I'm replacing it is for safety reasons.
