A charged compact star model has been determined for anisotropic fluid distribution. We have solved the Einstein's-Maxwell field equations to construct the charged compact star models by using radial pressure, metric function e λ and electric charge function. The generic charged anisotropic solution is verified by exploring different physical conditions like, causality condition, mass-radius relation and stability of the solution (via. adiabatic index, TOV equations and Herrera cracking concept). It is observed that the present charged anisotropic compact star is compatible with the star PSR 1937+21. However we also presented the EOS ρ = f (p) for present charged compact star model.
