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. …

Wire split and short-circuited!
The cord on this power supply is very flimsy (about the same diameter as a mouse cable) and split at the base. Now I'm out of $80 The cord on this power supply is very flimsy (about the same diameter as a mouse cable) and split at the base. Now I'm out of $80 bucks. This is one of those devices that you focus more on the function of the object rather than the form. You can't expect us to not bend the (ridiculously short) cable while we move around and charge! Also, the power supply is where the plug is, making the charger take up 2-3 plug spaces when put in. Finally, one day, the plug was bent too far and the cable split. As I was unplugging the charger, I heard a hissing sound and my hand got a very minor (but painful) burn. …

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. …

If the ports of the adapter fit your macbook air, it means it is designed to be compatible with the If the ports of the adapter fit your macbook air, it means it is designed to be compatible with the air.
So answer is yes if the port fits. 85W just means that it has larger capability of supplying larger current with the same voltage when it is necessary. So when you plug 85 W power adapter into your air, it will give just enough current to the Macbook Air. Since the voltage is kept the same, it won't cause any problem. …
