The charging port is clean, it's a 45 watt block that works fine with a slow cable, but using a cable that supports super fast charging makes the charge constantly click on and off. I've always used a slow charger because of this, and I have bought many different chargers and cables that have done the same thing

I don't know for sure, but is it possible that super fast charging may cause the phone to overheat, so charging stops while it cools down?

It only clicks off for 1 second, and does this every 10 seconds

Still could be heating and cooling. If the charger, cable and charging port work on slow charging (is it slow charging or simply fast charging?), it's likely not a problem with any of those. I can believe this is a protective measure, as super fast charging is likely to tax the battery. On the rare occasion that I put my phone on the super fast charger, I do not watch it charge, so I don't know if it alternates on and off as a normal occurrence, but I have seen a handful of inquiries about it.

You should download Good Guardians from the Galaxy store and then the thermal guardian module.  It will be able to tell you if your phone is going over the temperature threshold during charging.

 The dotted line is the threshold, the orange dots are points where there was activity.  Clicking on one of the dots will tell you what was going on at the time.  The blue shadow is when it's charging.  So, you can see from the photo above, that I had a period of high heat during a charging cycle.

It's been plugged in for 10 minutes, says it's fast charging, and it's dropped from 20% to 8% battery.

I noticed that the pause only comes when you have the cord plugged in wrong. Maybe it's you have to have both the same direction? Just try flipping one end of the cord over and plug it back in.
