It's sort of worse too because some which charge don't Quick Charge and SWMBOs Moto has a later standard (Fast Charge I believe).
This para may be rubbish as I've not managed to verify it. But the colour of the plastic bit in the computer end of the socket (USB-A?) seems to be significant. Blue quick charges (QC) and purple Fast Charges (20W) as far as I can see. Obviously your equipment (both ends) also needs to support whichever standard you're trying to use, whether it's a charger or a computer. Doesn't help much with data though, but I suspect that cables supporting the later standards are more likely to also support data transfer properly.
Must admit I've stopped buying cheap cables, and binned those cheap ones which don't work properly for me.
