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.

Works Fine - BUT PRICE IS RIDICULOUS
I've got a MacBook Air 13" (2011) that I feel is the finest travel computer for a businessman ever invented. I love this little w I've got a MacBook Air 13" (2011) that I feel is the finest travel computer for a businessman ever invented. I love this little workhorse. Also, the power adapter on mine works just fine ... no problems. Instead of unplugging every time I hit the road, I thought it would be a good idea to buy a spare for my computer bag. Wrong!
$79.95? Is this someone's idea of a joke? Eighty bucks for a power adapter? Sure the cell phone manufacturers have run this scam for years, refusing to standardize on a plug configurations/power ratings so that the buyer is forced to buy yet another power adapter (I've got about twenty of them sitting in a drawer). But those pieces of junk are only $20 or $30. $80? For what?
I've got AppleCare, so I'll just keep on plugging in and unplugging the one adapter I have until it dies, then you can replace it for free. Really, you folks at Apple build the coolest stuff on earth, but you do need to re-think your policy of over-charging for the small stuff. …

This product needs a recall
Have treated my charger very carefully. Have not wrapped it too tight and have always avoided putting stress on either end of it. Have treated my charger very carefully. Have not wrapped it too tight and have always avoided putting stress on either end of it. It's now failing at the power supply end around the grommet. My previous Macbook chargers (which are all several years older) have had no issues with the same degree of care given them. This is a shoddy product. Will not be buying an air again because of this. …

Long-term excellent durable if treated a certain way
This goes against the grain of reviews, but here's my experience. I have had three Apple white power bricks, each outlasting the l This goes against the grain of reviews, but here's my experience. 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 white box is a built in power converter so you should be fine with plugging it in as long as you The white box is a built in power converter so you should be fine with plugging it in as long as you have the adapter that changes plug types. You can check to see if other things are converters if it has something like Input: 100-240V~1.5A 50-60Hz. This shows that an electric current of 100-240 Volts can power the converter without problem, which Spain's electricity falls in. If you cannot find this on a product (though most electronics made in about the last 5-10 years automatically convert) or if you feel you would rather side with caution you can but a converter, but only leave it plugged it when you need the power because converters burn out quickly from overheating if you leave them plugged in too long. …

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. …
