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 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.

      Is apple even reading these reviews?

      These chargers are the most poorly made electronic accessory I have ever owned. I'm always careful about wrapping it it up properly before putting it away but t These chargers are the most poorly made electronic accessory I have ever owned. I'm always careful about wrapping it it up properly before putting it away but the cord is still frayed within a year. I now buy them non-genuine from Amazon and they're way better and WAY less expensive.

      Worst design of the Mac charger.

      Not only does this charger fray and break incredibly quickly (in a time that is ridiculous for the price of the product) and is used as fast as a disposable wip Not only does this charger fray and break incredibly quickly (in a time that is ridiculous for the price of the product) and is used as fast as a disposable wipe, but the charger does not stay in the computer well. The magnet is weak and the part of the charger that plugs into the computer is so short, there is no way you could've thought this would stay in. Honestly I wonder why you even thought to release such a bad product at all, let alone at such a ridiculous price! This is outrageous. Fix this.
