Apple cares about its brand. Chinese no name vendors don't at all, it's horrifying what plain illegal corner-cutting they often engage in. But that's of course what they're rewarded for.
In fact, if you're in a bind and need a USB C charger that will work reliably, you may want to pay the cost to get a genuine Apple one. (I won't order Apple chargers from Amazon; I get them direct from Apple or a real retailer because I don't trust the co-mingling).
