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.

Poor design: bad angle, inadequate magnetic pull
There are three problems with the new MagSafe: 1) the cable projects from the overly wide connector at a 90 degree angle. This mea There are three problems with the new MagSafe: 1) the cable projects from the overly wide connector at a 90 degree angle. This means that if the computer and MagSafe are not completely level, it falls out. So the "laptop" has to be "table top-only" if you want to charge it. Add this to the flaw (2) of inadequate magnetic pull, and it's a disaster. If there is any grit in the power outlet in the MBA, the weak pull is lessened. The charger constantly falls out. 3) The coating on my cable nearest the connector (perhaps because of its 90 degree projection?) got stressed and split. Now I need to buy a new one as the internal wiring is exposed. This has never happened with any Apple cable before, and I am a long-term user. It has to be the design of this one.
Apple, please, go back to the old design of the brilliant MagSafe 1. And offer it for the 2013 MBA. …

What an awful design Now on number 3 in <4years.

The slightest pinch in this, usually caused b The cause of replacement number 3 is the useless covering on the magsafe cable end. The slightest pinch in this, usually caused by being laid under the world's lightest computer, and it crumbles. While it's crumbling at one point the sheathing slides up and down, breaking at subsequent points along its length. Which is bad - but it gets worse. You cannot detach the cheap cable from the expensive box of electronics. Seriously guys, 4 years and you've not addressed this yet. Bad design flaw! Get it? Making the product universal with only 1 cable change for the global market is a good idea. Making us throw away a working and expensive box because you can't get a cable covering right is a bad idea. Let me demonstrate:
Let's ask a 5 year old how we could improve that, shall we? How about you makek the cable that disintegrates detachable from the big expensive box of equipment so my replacement cost each year is smaller?
Or do Apple genuinely want to penalise their customers by failing to make the product properly in the first place and then compounding that by charging us unnecessarily for a part that is still working but that we cannot get off the end of the cable to allow us to replace the cable that needs changing? Seriously? Yes, it would still be a pain, but a pain that wouldn't bankrupt me. …
