You could literally use one of those bog standard black PC laptop chargers as a weapon and it would be fine. Those things are indestructible. You could repel off a cliff with one. Have you ever seen one frayed or damaged at all? I haven't. Meanwhile, go to any college lecture hall and you will find about half the macbook chargers are covered in tape or frayed. This is "You are holding it wrong" all over again.

Maybe the macbook charger is stronger than your expensive RF cables, but it is far weaker than anything else the competition puts out and that's a huge annoyance, as a mac user myself who gets maybe 3 years out of a given apple cable, be it magsafe charger, lightning cable, or even the wired headphones. It's a distinctly Apple issue, cables in my hands from other manufacturers, even no name junk looking cables, don't have these issues.
