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.
