The 45W MagSafe 2 Power Adaptor 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 adaptor for maximum lead length, while the AC wall adaptor (also provided) gives you an even easier and more compact way to travel.
Designed to be the perfect travelling companion, the adaptor has a clever design that allows the DC cable to be wound neatly around itself for easy cable storage.
This power adaptor 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.

Broke too soon
Quite careful with my equipment. This one simply stopped working under no significant stress conditions. Quality control alert.

Worst Apple product or accesory
This is like a bad dream. When I saw the reviews I thought they were joking. I feel like sending the entire laptop back because of the adapter. It falls off for no reason and gets in the way. Apple needs to do a recall. …

Well both these reviews are right in their own ways. The charger is great for what it is designed to do. However you have to pro vide it a little more consideration than some other cords. I have broken 2 by my own fault as one I twisted too tight around the built in holder and the other my 8 year old autistic son broke after 6 months of hard use. Look apple can't be blamed for moves like that. In fact the genius bar would have replaced the first one under warranty but I don't play that way. So for my money the product is fine, and I'll put my 15 bucks a month away and replace the charger if I need too, I waste more money than that on coffee. …

I did nothing wrong to this charger and it just fell apart one day. I take great care of my tech and equipment, but one day I unpl ugged it and it just broke. Luckily I get a free one with my warranty, but only for another 30 days. And $79?? For this?? Come on Apple. Please make a better quality product. …

What the heck?!?!
That I must purchase a new power adapter after LESS THAN 6 MONTHS of owning my MacBook Air is RIDICULOUS. I am obsessively carefu l about taking excellent care of my computer and all its accessories. Pathologically careful, in fact. Seriously, Apple... …

Very poor quality! This charger only lasted 1.5 years. Annoying to have to replace so soon (or at all).
