Question about Aukey Omnia Mix3 PA-B6S

USB-C 1 + USB-A: 60W + 30W (Max 90W)
USB-C 1 + USB-C 2: 60W + 30W (Max 90W)
USB-C 1 + USB-C 2 + USB-A: 60W + 12W + 12W (Max 84W)

I think the question is about whether both USB-C ports could in theory deliver the 90W, regardless of the fact that you can't run both in parallel at 90W.

I just tested the whole thing and both the port labelled "PD" and the lower port with the laptop symbol deliver 90W on my MacBook when none of the other ports are used in parallel.

I know the data. But are there differences between the USB-C: can they both deliver 90 on their own, or only one?
