The really janky ones you get with like USB gadgets like fans only have the 2 power lines hooked up and not the lines needed to communicate PD support, those will work exactly the same as the same janky USB A-microUSB cables they used to come with, supplying 5V/2A. You throw those away the second you get them and replace them with the decent quality cables you bought in bulk from AmazonBasics or something.
The cheaper aliexpress item you actually want is this one, it will read the emarker and tell you the power/data rates it supports, if it supports thunderbolt etc https://www.aliexpress.com/item/1005007287415216.html
