  We study a model with a vector dark matter candidate interacting with the SM
charged leptons through a scalar portal. The dark matter candidate acquires
mass when the scalar breaks spontaneously an abelian gauge symmetry. The scalar
mediator being leptophilic only induces elastic scattering of dark matter with
electrons at the leading order (tree level). Given the recent results from
Xenon1T upper bounds where the strongest sensitivity lies in the range $\sim
{\cal O}$(1) GeV, we find the viable space in the parameter space respecting
constraints from the observed relic density, muon g-2 anomaly, $e^+ e^-$
colliders and astrophysical observables. It is shown that the current upper
bounds of Xenon1T is partially sensitive to the viable parameter space, such
that it excludes the scalar mediator with masses $m_s \lesssim 3$ MeV for DM
masses $m_{\text{DM}} \sim 0.1-10$ GeV.
