Question about Aukey OmniaMix II

a priori no, it outputs 140W on 3 ports, on a single port, it's 65w max from memory. So you should be able to charge your MB, but not in fast charge mode.

According to Aukey Malaysia's website, both USB-C ports can output up to 140W (28V / 5A) when only one port is occupied.

USB-C 1/2: 5~11V/4.05A (PPS), 5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/5A, 28V/5A (140W Max)
USB-A: 5V/3A, 9V/3A, 10V/2.25A, 12V/1.25A (22.5W Max)
USB-C1 + USB-C2: 65W+65W (130W Max)
USB-C1/C2 + USB-A: 100W+22.5W (122.5W Max)
USB-C1 + USB-C2 + USB-A: 65W+45W+18W(128W Max)
