TL;DR Summary
When i used powerbank circuit board to charge super capacitor, the speed was too low.
What is the fastest circuit to charge a supercapacitor?? could you show me??

Can you link to the datasheet for the supercap that you want to charge? What are you wanting to use it for?

I think that the original supercaps were very limited in their peak current capabilities (for charging and discharging). I think that the newer ones are better, but I'm guessing that they are still limited...

The speed is mostly depend on model of super-capacitors and allowed surge current. Many charging boards have build-in current limiter, you should consult the specs. Supercapacitor banks assisting battery in hybrid cars are designed to be charged in one minute, while the fastest supercapacitor i seen (used to drive electrical detonator of explosive bolt) was rated for 0.05s.
