Apple 45W MagSafe 2 Power Adapter for MacBook Air

Get help buying. or call 1-800-854-3680.
  • 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.

      3 broken within 3 months

      I have had 3 separate chargers break within the first 3 months of owning this computer. It's ridiculous how cheaply they're made, and how easily they break.

      Dead after a year and a half

      I keep my charger cable on my desk and only rarely travel with it. Brand new in April 2016, today (Jan 2018) the cable has abruptly stopped charging. Less than I keep my charger cable on my desk and only rarely travel with it. Brand new in April 2016, today (Jan 2018) the cable has abruptly stopped charging. Less than two years of sitting on a desk, and the cable no longer works. Replacements are $80. Seems like Apple is purposefully making poor quality accessories so you are forced to keep buying new ones.
