Why is it dangerous to chain power dividers? (sopuli.xyz)

Besides putting too many devices on a single wall socket, that draw too much power, what is supposed to happen?

Like say I chain ten dividers and put a single vacuum cleaner at the end. Is that more dangerous than plugging it directly into the wall?

The longer the run with more connections, the greater the voltage drop, the more stress on anything involved.

That means more power usage and higher likelihood of a failure vs directly plugging the same device into the outlet. So it is better to use an extension cord than chained power strips.

It is especially dangerous to have chained power strips that you load up due to fire risk that isn't necessarily mitigated by the breaker.
