Sure there is: How well a cable handles being bent, and whether or not it catches fire... Cables and especially chargers are some of the products I'm most cautious about buying from sellers I'm not confident about exactly for that reason.

(not that origin is sufficient - the one charger I have had that got closest to setting the house on fire was a genuine Apple charger [many many years ago, they had a design flaw with a too-short sleeve on the cable on the early Macbook chargers; it'd bend and short and melt])
