Laptop charging cable from Powerbank?

Question

Lenovo

Good afternoon everyone!
Very, very need help!
please advise the cable for charging laptop lenovo ideapad 320-15isk (there is type-c) from UMB Xiaomi Mi Power Bank 3 20000 mAh PLM07ZM.
The standard one from UMB does not fit, which seems logical ... I found the HOCO X23 Skilled White USB Type-C to USB Type-C cable,
but it didn’t help either (((
I don’t know what I’m doing wrong, all hope is on you

Nowhere did I find information that the available USB-C can be used to charge the laptop itself. Where did you get that from??? Usually, for advanced laptops, one of the available USBs can be used to charge the mobile even from the switched off laptop. I guess USB-C is for the same. However, you will need a USB-C <-> USB-C cable. I have never seen such a cable, it is some kind of rarity. So leave this idea, it is not feasible.
But you can charge a laptop from Powerbank. To do this, you will have to increase the voltage of 5 volts from the Powerbank to the required 18 ... 19 volts for the laptop and apply them to a standard charging socket. Soldering such a booster is not difficult, since Ali sells a variety of power supply modules, incl. and such. But charging will be long and partial, since the Powerbank has a small supply of energy (it is much larger in the on-board laptop battery). The laptop will not be able to work directly from the Powerbank - there will not be enough current that, according to the specification, can pass through the USB port.
