How to understand if a cable is PD for fast charging?

Hi, I have various camcorders, cameras, laptops, lamps, etc, etc. some have batteries with the capacity to accept a fast charge, so they need a suitable PD cable for fast charging.But unfortunately my USB C cables have all mixed up and I no longer know which is from one product and which is from the other..How can I distinguish the various cables and take the right ones for fast charging?Thanks for some info.
