Apple 45W MagSafe 2 Power Adapter for MacBook Air
Apple 45W MagSafe 2 Power Adapter for MacBook Air
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.

Very poor indeed. Not fit for purpose.
I bought a new Macbook Air 13" (2013) and this is the power adapter that comes with it. I had an older Macbook Air that used the I bought a new Macbook Air 13" (2013) and this is the power adapter that comes with it. I had an older Macbook Air that used the earlier magsafe connector. The magsafe 2 is absolutely hopeless. It disconnects from the laptop at the slightest movement. I never had a problem with the previous connector. It is impossible to use the laptop on a lap as the magsafe 2 disconnects much too easily. It juts out from the side of the laptop and looks clumsy and crude.
Not only did I find the magsafe 2 an absolute nuisance to use but the whole charger failed after less than a week having got far too hot. I took my new Macbook Air back to the shop for a refund. Apple should be ashamed of this. This is terrible design and very poor quality. This is not what customers expect from a premium brand.
The product should be recalled as it is not fit for purpose. …

Annoying and Comes unplugged.
The new charger falls out all the time. I put my laptop on my bed, charger falls out. I accidently scrape the charger's wire, char The new charger falls out all the time. I put my laptop on my bed, charger falls out. I accidently scrape the charger's wire, charger falls out. I place my laptop on my desk at a slight angle, charger falls out. You're getting the idea. It is very annoying when I put my laptop to charge, leave it and come to use it away from the house to discover it wasn't charging since the plug fell out. This is the one thing that is wrong with the new MacBook Air. Shame really. …

Poor design: bad angle, inadequate magnetic pull
There are three problems with the new MagSafe: 1) the cable projects from the overly wide connector at a 90 degree angle. This mea There are three problems with the new MagSafe: 1) the cable projects from the overly wide connector at a 90 degree angle. This means that if the computer and MagSafe are not completely level, it falls out. So the "laptop" has to be "table top-only" if you want to charge it. Add this to the flaw (2) of inadequate magnetic pull, and it's a disaster. If there is any grit in the power outlet in the MBA, the weak pull is lessened. The charger constantly falls out. 3) The coating on my cable nearest the connector (perhaps because of its 90 degree projection?) got stressed and split. Now I need to buy a new one as the internal wiring is exposed. This has never happened with any Apple cable before, and I am a long-term user. It has to be the design of this one.
Apple, please, go back to the old design of the brilliant MagSafe 1. And offer it for the 2013 MBA. …

Not very safe
I had this power adapter for 1.5 years and it's now damaged. The cable broke and it wouldn't charge anymore.

Works perfectly - even with rMBP15
Bought this for work and travel as it is a lot smaller (fits nicely in Knomo bag) than the 85 W and I rarely need the discreet gra Bought this for work and travel as it is a lot smaller (fits nicely in Knomo bag) than the 85 W and I rarely need the discreet graphics of the 15" rMBP when not at home. Works flawlessly.
The heating issues described must be related to the input voltage as I have never experienced anything close to overheating on Danish 230 V. The MagSafe 2 plug fastens securely to the rMBP, too. Less so to the MBA13 - but have never had an issue worth mentioning (though I do have to pay a little attention to it when in bed/on the sofa). …
