  We consider a dust ball with an electrically charged central core and study
its quantum spectrum by quantising the geodesic equation for individual dust
particles in the corresponding Reissner-Nordstr\"om spacetime. As in the
neutral case investigated previously, we find a ground state of the dust ball
with the size of a fraction of the outer horizon. Moreover, we determine a
self-consistent configuration of layers in the ground state corresponding to an
effective mass function that increases linearly with the areal radius and has
no inner horizon.
