USB-C supports many voltages and there is a protocol for the power supply and the device to negotiate the requirements. You have a laptop that needs 20V and a power bank that only outputs 5 volts. If you look at your charger that came with your laptop, it can output 5V for your phone or 20V for your laptop. (also 9V and 15V) You need a better or smarter powerbank
