What is the max output power for a single port on this power bank?

The USB-C port alone supports up to 100W output (requires a PD 3.0-compatible device and 100W-rated cable). When using both USB-C ports simultaneously, total output reaches 145W combined.

Why does charging slow down when the power bank is above 80% battery?

This is intentional battery protection! Above 80% charge, the system switches to trickle charging to extend battery lifespan and prevent overheating. The display will show the current input power, and estimated full charge time may increase.
