My takeaway from this is that the $80 Apple charger is definitely safer and has higher-quality components than the $12 cheapo Chinese charger, but not nearly so much better that it solely explains the price difference, and that Apple is making a healthy margin on these things. So my question is, is anyone selling a quality charger without the Apple tax? Is there anyone making, say, $40 chargers that have the components of the real thing?

Hidden gem in this article is a comically bald-faced lie from Steve Jobs:

> "That switching power supply was as revolutionary as the Apple II logic board was. Rod doesn't get a lot of credit for this in the history books but he should. Every computer now uses switching power supplies, and they all rip off Rod Holt's design."

Fascinating. The magsafe connector is awesome in preventing something snagging the cable from dragging your laptop along with it.

But, as the article says, reliability is a problem. The thing is definitely not toddler-proof. I have a 2012 Macbook Air, and I'm on, I think, my fourth charger.

It may not quite be true, but it's not necessarily a lie. People often don't realise where an invention came from.

Had a 2011 Macbook Pro. Was always very nice to the charger, never abusing or dropping it. But Apple's decision with all their cabling to not incorporate strain relief was frustrating. I went through four chargers in four years.

Why does Apple continue to ignore strain relief on their cabling?

I've bought two replica chargers for $20-30 off ebay.. i'm on my second. The first one lasted a year, which is about how long my original charger lasted due to the cord fraying

Or is there a charger at Apple's price, but more reliable?

The OP shows why replica chargers are not a good idea. You're lucky if it doesn't destroy your machine.
