  By replacing the scalar $\phi$ with $i\phi$ in the solution constructed in
Ref\cite{Huang:2019lsl}, we obtain electrically-charged wormhole and black hole
solutions in the Einstein-Maxwell-scalar theory, in which the scalar is a
phantom field coupled to the Maxwell field non-minimally. Our solutions are
simpler than the previously-known charged wormholes in the
Einstein-Maxwell-dilaton theory in that both the scalar and the radius of the
foliating sphere of our solutions are independent of electric charge. The
wormhole solution has two asymptotically flat regions and reduces to Ellis
wormhole when the charge is zero. We draw the embedding diagrams for the
wormholes and demonstrate that the two sides are asymmetric. As the charge
increases, horizons will appear, and the wormhole becomes a black hole, with no
curvature singularity but a wormhole throat or a bounce. We analyze black hole
thermodynamics and the causal structure. We also determine the photon spheres
of both the wormhole and the black hole and discuss their observable
characteristics.
