I believe that explicite equations for masses of cosmological and quantum black holes should resolve the problem of adopting the Schwarzschild radius to a quantum black hole!
Jamil Kooli There is a lower limit on the possible size of black holes. It is around 3.4 solar masses.
Data Black Holes
The reason for this is that there is a limit on the possible density of matter. This limit corresponds to the density of a proton or neutron.
For any object to become a black hole with radius R, all the mass has to be concentrated within that radius and the density limit rules out the possibility of primordial or quantum black holes.

A black hole is a classical object, a solution of Einstein’s equations, so the term ``quantum black hole" just doesn’t make sense. Nor does the term ``cosmological black hole": A black hole has a future singularity, the Universe has a past singularity.
All this is known, so it would be useful to study general relativity, first.
As any classical object, a black hole is a limiting case of a quantum object. Some properties of these quantum objects, namely their entropy, are known, though a lot remains to be understood.

I think people are mistaken if they think they can continue to promote fundamental physics if they don't specifically pursue the work of Einstein and Planck. The latter and Einstein did not complete their research. If people relate the research of these eminent physicists to cosmological constants, they will find that they can calculate everything infinitely large and everything infinitely small in the universe. For my part I discovered that Planck's constant is a function of cosmological constants and I discovered that the reduced Planck's constant is a function of cosmological constants and that special relativity can be related to cosmological constants but for me the cosmological constants are related and come from each other but also general relativity also uses the cosmological constant(s) so these theories are related via the cosmological constants and I realize that must be a certainty.

According to me there are between 5 and 10 cosmological constants that people don't know yet and the real number can be much higher, these are the ones I'm talking about. I am certain that these constants when used with the planck units and general and special relativity will allow people to link these three theories. I have an example i believe that the value 72.4 km/s/Mpc (Freedman et al.) relate to the local zone it is the Huble constant. I believe that the value 67.4 km/s/Mpc is the expansion rate of the early universe. I believe that the value 67.4 km/s/Mpc is a new cosmological constant. And i believe that the value of HA and the value 67.4 km/s/Mpc are in close link. I'm working on an expansion of the two theories of einstein and this of Planck relating to the Planck unties i incite people to work on this direction in this domain Eintein and Planck are the best for ever (Past time, present time, and future time). I find that the majority of new theories are not purely fundamental, I find that they are rather better suited for experimental physics.
