In this work; we consider the possibility of constructing gravitationally bound; charged dark matter halos motivated by Einasto density model. This model generalizes the concept of charged; non-commutative mini-compact objects by including dark matter as its primary component through the principles of the minimal geometric deformation strategy. We point out that the coupling of the non-commutativity inspired Einasto spike density model with a non-isotropic fluid; within the context of gravitational decoupling allows the formation of different minimally deformed dark matter halos; corresponding to each value of the deformation parameter. We assume the Tolman-Kuchowicz cosmological model as a seed metric within the geometric deformation scheme to initially generate an electrically charged isotropic solution. Subsequently; we employ a density-like constraint to produce a second anisotropic charged dark matter stellar model via the Einasto density profile. A complete graphical analysis of the structural variables and stability of both models indicate that; for the considered choice of parameters; both cosmological models are well-behaved; exhibiting expected physical behavior. © 2024 IOP Publishing Ltd.
