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 had this product for about 14 months and it no longer works. The awful design makes it inevitable to break, but why is it not be I had this product for about 14 months and it no longer works. The awful design makes it inevitable to break, but why is it not being fixed? If this company is going to spend twice what it gains on technology to help the blind and deaf then surely the company can pay the small cost in comparison to fix the chargers. If you don't care about "the ROI" Mr.Cook then fix this issue immediately. …

Very poor product
I think anyone who has owned a Mac laptop knows by now that the power supplies are woeful. It is only a matter of time before the I think anyone who has owned a Mac laptop knows by now that the power supplies are woeful. It is only a matter of time before the thin cable and sleeving starts to split and the wire gets exposed and shorts leaving you with a dead unit. You have to wonder, is this designed in obsolescence? With replace power supplies costing £65 each and with so many reviews of how poor quality the product I think people will be able to draw their own conclusions. Unfortunately we are all captive consumers as there is no real quality alternative, we just have to stump up £65 each time our power supplies fail. You could perhaps forgive Apple if it was an interim issue, but this type of power supply has been in production for a long time now....come on Apple, please step up and address this issue. …
