Apple 45W MagSafe 2 Power Adapter for MacBook Air

  • 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.

      The price of replacement is a big negative. $99. The first cable is sensitive to any damage (the extension cable is more robust).

      Awful quality and don't last very long.

      Lasted for about 3 years which is good i suppose and why i gave 2 stars but for £79 i dont expect wires and the rubber to easily peel off and expose wires. Mine Lasted for about 3 years which is good i suppose and why i gave 2 stars but for £79 i dont expect wires and the rubber to easily peel off and expose wires. Mine is breaking and i'm forced to buy this one. Way too expensive for the quality and the charger length is not very long! I hate it but it did last for 3 years but i was hoping it would've lasted me until i needed to buy another computer.

      Love my MagSafe 2

      Seeing all these negative reviews has prompted me to add a bit of balance. I've had my MBA for about 5 years and power cable looks and works like new. It is fai Seeing all these negative reviews has prompted me to add a bit of balance. I've had my MBA for about 5 years and power cable looks and works like new. It is fairly light and compact and plenty long enough. I just love the magnetic connection and the little light on the connector indicating whether the battery is fully charged. Definitely a design classic and a shame that it has been superseded on new MacBook models.
