The USB-A ports on the Mac mini are spec'd as USB 3.1 Gen 2.

The technical specification for USB 3.1 Gen 2 is a max power rating of 4.5W at 5V, with max current of 900 mA.

Generally speaking, Apple tends to stick to specifications, even if they don't make it easy for users to find those specs for each particular Mac.
