just to note, wireless charging is very inefficient. From the page you linked:

"Due to a 30% to 45% energy loss in battery cells and conversion circuitry, a fully charged 5,000 mAh power bank typically offers an estimated 2,750 to 3,500mAh to power devices"

Then use the supplied USB-C to USB-C cable for more efficient charging, while using the magnets to stick it to the back of your phone.
