Regular black hole solutions are found among the Guilfoyle exact solutions.These are spherically symmetric solutions of general relativity coupled toMaxwell's electromagnetism and charged matter where the metric potentials andelectromagnetic fields are related in some particularly simple form. We showthat, for certain ranges of the parameters, there are objects which correspondto regular charged black holes, whose interior region is filled by anelectrically charged phantom-like fluid, or, in the limiting case, a de Sitterfalse vacuum fluid, and whose exterior region is Reissner-Nordstr\"om. Theboundary between both regions is a smooth boundary surface, except in thelimiting case where the boundary is made of a massless electrically chargedspherically symmetric coat. The main physical and geometrical properties ofsuch charged regular solutions are analyzed.
