To charge a MacBook Pro from the USB C connector, you need to close the lid or set it to sleep mode. If you charge it while working on your MacBook, 18W from the Air Omni may not be sufficient to offset the power that the MacBook Pro consumes. And the MacBook Pro features a big battery capacity, so it will take some time to charge it from an 18W PSU.
