Apple 45W MagSafe Power Adapter for MacBook Air
Apple 45W MagSafe Power Adapter for MacBook Air
The 45-Watt MagSafe Power Adapter for MacBook Air features a magnetic DC connector that ensures your power cable will disconnect if it experiences undue strain, and 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 will light up; an amber light lets you know that your portable 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 users an even easier and more compact way to travel.
Redesigned specifically for MacBook Air, the adapter is the perfect travelling companion. It 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 with MagSafe Power Port.

Flimsy would be a generous adjective for this charger. It's actually quite dangerous how easily this breaks and had I been a bit less careless, I could've had a nasty shock. I will not be giving Apple the satisfaction of getting an extortionate replacement from them when there are far cheaper alternatives. …

I have had three Apple white power bricks, each outlasting the laptop it came with (the weren't all 45W Magsafe – the first was the co-axial plug-in type with a white iBook, the second a 60W Magsafe with a Macbook and the current one a 45W Magsafe with an Air). I travel several days a week. I'd estimate I coil and uncoil the wire at least 10 times a week, several hundred or a thousand times a year, several thousand times in the time I've had the adapters.
But I always make sure I'm not allowing the wire to become twisted or strained. Where it emerges from the brick itself, I let it turn very gently through 90 degrees and then start wrapping the wire around the folding plastic 'ears', gently on the first lap and tightly thereafter. With each turn, I give the cable a twist with my thumb and forefinger to counteract the natural opposite twist it would otherwise get. And as I uncoil it I do the opposite. It doesn't take any time. Apple should put this in the instructions. It's the same way any sailor or trucker would coil up a rope, or gardener coil a hose, to stop it twisting and getting knotted and strained. …

The first one di I am now at the point where I have to buy the fourth charger for this Macbook air which is not even 3 years old.
The first one died within 3 months and was replaced under warranty, the second one died 18 months later and the third now needs replacing after less than 10 months of use.
How can you justify such a badly designed product at such a high price?
I was considering buying another Macbook Air for my son, I am now seriously reconsidering.
This charger is pathetic. …

Grounding my macbook air
- Asked by Angela K from Dartmouth
One is grounded and the other is ungrounded as you mentioned. I find that it is very important to us One is grounded and the other is ungrounded as you mentioned. I find that it is very important to use the three prong/grounded plug when ever you can, just because it is safer. The two prong is great for when traveling since you don't need to carry an extra 3 foot cable with you. Others and I have also found that the MacBooks heat up less when using the grounded cable.
The only real difference is convenience for the consumer.
Hope this answers your question. …
