Apple 45W MagSafe 2 Power Adapter for MacBook Air

Get help buying. or call 133‑622.
  • 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 one star reviews are not warranted

      I really don't understand why there are so many 1 star reviews on this charger! I have had a Macbook Air since 2014 and I got my current one in August 2017. I h I really don't understand why there are so many 1 star reviews on this charger! I have had a Macbook Air since 2014 and I got my current one in August 2017. I have been using the same charger this whole time (around 5 years because the same charger is compatible with both of my Macbook Airs) and it only just started to fray. The only thing that is annoying is that because the charger is magnetic it is constantly getting disconnected by any little thing. I have 2 dogs so this happens all the time! It's not that big of a deal though and it's easy to transport in my backpack for school. It's a good charger in my opinion. Also, I used to have a Dell laptop and that charger only lasted a year. In comparison, this is a really good charger.

      Awful Quality

      Just about to order my 3rd replacement charger cable in 3 years. My charger never leaves the house so is not screwed up in a bag to get damaged. Far too flimsy, Just about to order my 3rd replacement charger cable in 3 years. My charger never leaves the house so is not screwed up in a bag to get damaged. Far too flimsy, not the usual Apple quality.

      I think this charger is just fine

      I was reading the reviews of this charger and the majority of them are all one star and everyone seems to have so much trouble with this charger. I, on the othe I was reading the reviews of this charger and the majority of them are all one star and everyone seems to have so much trouble with this charger. I, on the other hand, have never had any issues with it at all. The magnetic aspect is very cool and works just fine. The charger is super fast and has never shorted out on me before. Ive had mine for about 2 years now and it is still completely free of any wear and tear. Also, the green and orange led on the charger is very helpful because I don't like to leave my MacBook plugged in when it is already fully charged, and the green led always lets me know when it is time to unplug.
