How can the changing cord could be fast or slow charge?   I understand the charger but the cord itself...  There;s no components to it.
This one for example:

Is it a fast or slow charge?

If the cable is up to spec (came with the device), there is no such thing. As long as the cable handles the current (and manufacturer's cables will) then they will all work the same.

Substandard cables (thin wires) may be slower because of higher internal resistance in the thin copper wire.

I note a particularly humorous selling point:

"We cannot guarantee that the cable is capable of transferring data."

Exactly what one wants in a USB cable!

it depends on the wire gauge, and the length; the one one you linked is only 1 m long, if you have longer one,  it may limit the current (higher resistance)
also - the contacts must be able to handle the current, so with USB c you'll have not the highest current transfer
