Probably worth figuring out what the problem is before one wrecks the nice

I tested it with another cable but same charger and iPad overnight.
It didn't get hot.
So, I think it's the cable.
Possibly, even likely, that "it's the cable". But the lesson to be leaned is that if one in six is bad, that is a pretty wretched record. And whether at 5V or 50V, 5 amps is a considerable amount of current that *will* melt fine wire if shorted. So, poor quality control is a real concern. Are the remaining five ticking bombs, or are you *sure* it is just this one cable?
Put another way, you get what you pay for.
Put yet another way, do not rely on your equipment to protect itself from a bad peripheral.
I could purchase a Rolex watch when we were in China for US$5. It said so right on the watch!!
