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; 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 cord is provided with the adapter for maximum cord 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 traveling companion. It has a clever design which 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. …

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. …
