  Extending previous work on the formation and the evaporation of black holes
in conformal gravity, in the present paper we study the gravitational collapse
of a spherically symmetric and electrically charged thin shell of radiation.
The process creates a singularity-free black hole. Assuming that in the
evaporation process the charge $Q$ is constant, the final product of the
evaporation is an extremal remnant with $M=Q$, which is reached in an infinite
amount of time. We also discuss the issue of singularity and thermodynamics of
black holes in Weyl's conformal gravity.
