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.

      Garbage

      I have been an apple owner for 2 decades. other than the original mac book with the awful hinges, this is hands down the worst product. It frays and shorts out I have been an apple owner for 2 decades. other than the original mac book with the awful hinges, this is hands down the worst product. It frays and shorts out at the magnetic end of the adapter. It does not matter how gentle you are. Apple, you should fix the issue, and replace these for free. This is the kind of issue that makes you lose customers, and yet you do nothing.

      Mine lasted 6 years

      My well abused power adapter has lasted 6 years and frayed cable at the computer end is the problem. I applied some insulation tape as additional support early My well abused power adapter has lasted 6 years and frayed cable at the computer end is the problem. I applied some insulation tape as additional support early on and perhaps others could do this. I bought one in ebay for £13 which lasted only 3 months before it died and I think wise to have genuine Apple product. Replacing the battery on the MacBook also helped as charge lasts much longer and less use of the adapter.
