Abstract
Previous discussions of charged dark matter neglected PBH spin and employed the Reissner-Nordstrom metric. In Nature we expect the PBHs to possess spin which require use of the technically more challenging Kerr-Newman metric. It is shown that the use of K-N metric retains the principal properties already obtained using the R-N metric, in particular the dominance of Coulomb repulsion requires super-extremality and the presence of naked singularities. In this sense, the spin of the PBHs is not an essential complication.
