  • 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.

      Terrible Product

      Even if you take special care, the cord will still fray and not last. Same thing happens for my iPhone charger. The quality is so poor that it makes me wonder i Even if you take special care, the cord will still fray and not last. Same thing happens for my iPhone charger. The quality is so poor that it makes me wonder if it is not done on purpose to force existing customers to purchase more after a short amount of time. It's unfortunate, because I love my MacBook and I've had it for four years, but I am tired of having to buy a new power adapter every year...

      Waste of money

      Beyond disappointed. I can't bring myself to buy another replacement (which I seem to be doing every year).
