  In the present article, we have constructed a static charged anisotropic
compact star model of Einstein field equations for a spherically symmetric
space-time geometry. Specifically, we have extended the charged isotropic
Heintzmann solution to an anisotropic domain. To address this work, we have
employed the gravitational decoupling through the so called minimal geometric
deformation approach. The charged anisotropic model is representing the
realistic compact objects such as $RXJ1856-37$ and $SAX J1808.4-3658(SS2)$. We
have reported our results in details for the compact star $RXJ1856-37$ on the
ground of physical properties such as pressure, density, velocity of sound,
energy conditions, stability conditions, Tolman-Oppenheimer-Volkoff equation
and redshift etc.
