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 cord is provided with the adapter for maximum cord length, while the AC wall adapter (also provided) gives you an even easier and more compact way to travel.
Designed to be the perfect traveling companion, the adapter 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 featuring MagSafe 2 power port.

Quite careful with my equipment. This one simply stopped working under no significant stress conditions. Quality control alert.

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. …

Bad magnetic connection and too wide- always disconnects!
This is the most annoying charger. I can't believe that a company, Apple, which prides themselves over such a simple, functional, This is the most annoying charger. I can't believe that a company, Apple, which prides themselves over such a simple, functional, high-quality level of design would release a charger like this! If your leg bumps it even a little (for example if your sitting on the couch with the computer in your lap) it disconnects because of its skinny, long and wide design. Apple- please give everyone who has a 45W MagSafe 2 power adapter a new one, similar to the old ones that are shaped less awkwardly! …

The magnet is very strong and Not sure what all the bad reviews are about, but I think this is the best charger on the market.
The magnet is very strong and I never have problems with it disconnecting easily. It has saved me a few times when the cord gets accidentally pulled and it disconnected instead of pulling my computer off the table onto the floor. The magnet makes it also super easy to plug in and its reversible so I don't even need to look when I plug it in.
Charges my computer fast and its got some nice features like the tabs for wrapping the cord, the removable wall plug adapter and a charging indicator light. It's also fairly small and compact.
I have had it for about a year and a half and there is minimal wear, and it works great. The cord wrapping design works OK in my opinion, and I can see how the cord could be damaged if its wrapped too tightly.
Having used PCs for most of my life I really think Mac users don't know how good they have it when it comes to the little things like the power adapter. Yes it costs a premium but its well worth it in my opinion. …

Compared to the magnificently engineered MagSafe Side adapter, the MagSafe2 cable Worth knowing:
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.
