  • 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.

      lasted 3 years

      With proper care the cable was in good condition for 3 years, but once the cord was damaged the rubber frayed very quickly.

      The most flimsy, overpriced charger!

      I too have ended up buying two already - each time resenting the money I keep spending. The wire always breaks from the same point - right at the top where the I too have ended up buying two already - each time resenting the money I keep spending. The wire always breaks from the same point - right at the top where the charges goes into the computer. I've always been proud of the meticulous care I take of my gadgets but this charger is so flimsy that no matter how careful you are, it's guaranteed to break. I almost feel it's a deliberate move by Apple to make sure the charger doesn't last more than a year and the clients keep buying more!
