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.

      Perfect in every way!!

      I have been using the original charger from my mac book air mid 2012 since I bought it. This is a great product from my experience. It was perfect. I recent I have been using the original charger from my mac book air mid 2012 since I bought it. This is a great product from my experience. It was perfect. I recently lent my laptop once to a friend for uni late 2018. I got the charger back with major damage which is why I never lent it out before when this friend asked once before a few years ago. This time I thought why not, I don't need it right now, her laptop is in for repair, sure. She never told me, never apologised, never mentioned the damage. I look after my stuff so well and I just don't understand how people break things so easily. People on average just seem to be rough and blame the manufacturers or the company when usually it's the persons fault. But they don't want to blame themselves. So like another person said, maybe I was just lucky, but I doubt it. On my experience with why I don't lend stuff out to people is because they just don't realise how rough they are with things and that they are the ones breaking things. Never lend your stuff unless you know the person takes care of things. I mean it, NEVER lend your possessions to people, even if they desperately need it for a uni assignment and try to make you feel bad if you don't. Disappointed in people who can't look after things. Rant over.

It isnt blinking. Then i had to buy another one. After around 2-3 months the charger isnt working again. The same thing, the light isnt blinking. Im thinking of maybe purchasing another macbook or maybe should i check my macbook AND the charger to apple store ? Im worried if i purchase another charger, the same thing would happen again.

      Very Poor Quality

      I am about to leave my office to purchase my third MacBook Air power cord (same MacBook Air), second in the last two years. I am the president of a company and I am about to leave my office to purchase my third MacBook Air power cord (same MacBook Air), second in the last two years. I am the president of a company and absolutely take extreme care when winding the thin cord around the two two braces. It is obvious that it doesn't matter how careful you are, the end of the cord that attaches to the power supply is going to fray and stop working. While I love the laptop, Apple should be ashamed for the way they build the power cord. I hate to say this, but it looks to me like this was a business decision by Apple to generate more revenue. If you rely on your MacBook Air for business like I do, I would suggest you always have an extra power cord available.
