Complicated adapter question wall male adapter for usb c female

Hi, bought a certain electronic device (blushield cube) (which by the way includes adapters for all continents), but it requires wall sockets. I want to use it when I’m on the go. I have a very good power bank (Portable-RAVPower-20100mAh) that I think may work, but it only charges via usb c and usb micro. What I want is to charge the via the plug that goes into the wall socket with my powerbank so I need an adapter. From Amazon.co.uk would be best
So: US wall male plug to adapter that has a US wall female input and which has a USB-C female to plug in the battery bank.
