Apple 45W MagSafe 2 Power Adapter for MacBook Air
Apple 45W MagSafe 2 Power Adapter for MacBook Air
The 45W MagSafe 2 Power Adapter features a magnetic DC connector so if someone should trip over it, the cord disconnects harmlessly and your MacBook Air stays put safely. It also 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 lights up; an amber light lets you know that your notebook 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 you an even easier and more compact way to travel.
Designed to be the perfect travelling companion, the adapter 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 featuring MagSafe 2 power port.

Only read reviews of MagSafe TWO - it's TERRIBLE!
All these reviews saying they've had no problems for over 6 months are reviews for other models. The new MagSafe 2 hasn't been ava All these reviews saying they've had no problems for over 6 months are reviews for other models. The new MagSafe 2 hasn't been available for that long - only since the new 2012 MBA's came out in mid-June. The new MagSafe 2's charger attachment magnet is incredibly weak and will detach at the slightest provocation. Or unhappy thought. Or suspicious look. This product is terrible and Apple should fix this as soon as possible. …

WHAT WERE YOU THINKING, APPLE?
I didn't think it was possible, but the power adapter for the MacBook Air is worse than the adapter for the MacBook Pro. Adding in I didn't think it was possible, but the power adapter for the MacBook Air is worse than the adapter for the MacBook Pro. Adding insult to injury, the battery life on the MacBook is so short, you're constantly using the adapter, and the smaller magnetic connector constantly disconnects. It's a badly designed product that should be recalled! …

How can Apple be so STUPID???
The Magsafe 1 adapter was great which I used on my 2011 MacBook Air. It never came off, I could use it on my lap, it never got in The Magsafe 1 adapter was great which I used on my 2011 MacBook Air. It never came off, I could use it on my lap, it never got in the way, it was just PERFECT and I just loved my MBA! But I guess some engineers from Hewlitt Packard decided to infiltrate the Apple Corporation with intent to infuriate customers, give them bad experiences with Apple products, and get them to cuss Apple. And they came up with the Magsafe 2 Adapter and succeeded at all three goals! This adapter cannot be used on your lap without it coming off every few minutes. I've been looking for solutions but there are not even any third party solutions, which Apple has been notorious for since their days of almost going bankrupt, but they still haven't learned. So, I think I will try some tape, or maybe some glue to keep it connected. Hey Apple, ever heard the phrase "IF IT AIN'T BROKE, DON'T FIX IT??? Thanks a lot, Apple. …

Compared to the magnificently engineered MagSafe Side adapter, the MagSafe2 cable is stiffer, coils poorly and the connector protrudes about 3/4 inch from the body of the mac.
In my humble opinion it is not as elegant an industrial design solution as it's predecessor. …
