Is that so? I assumed that a small black hole would rip apart a proton through spaghettification, therefore it won't have two up quarks and one down quark. But even if the charge remains, such information can't escape therefore its electric charge won't influence the universe.

I might need to read up more on this.

Yup, there's a theorem ("no-hair theorem") that the only information about a black hole which does influence the universe is its mass, spin, and electric charge.

Oh, I stand corrected.
