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.

      Very expensive and too frail

      This cable is too expensive for something that breaks easily. I got my laptop late 2015 and already it's broken. For something that breaks easily, why should I This cable is too expensive for something that breaks easily. I got my laptop late 2015 and already it's broken. For something that breaks easily, why should I be paying $80.00 for it. For a big name as Apple, this is so wrong and a rip off. If Im paying this much money on a laptop. Why is the quality of the cable so low??????

I only had to replace it earlier this year in February. Replaced it...and now it is broken again. Some might blame it on User negligence, but that's not me. Here goes another $80 (and tax...).

      Terribile upgrade

      The magnet is not strong enough to withstand the slightest jostle, constantly falling out of the computer. The old one worked much better. I don't understand The magnet is not strong enough to withstand the slightest jostle, constantly falling out of the computer. The old one worked much better. I don't understand why the change in shape. I thought the side mount with the cord to the rear was brilliant. It stayed firmly in place and kept the cord out of the way of papers I might be working on.
