The main objective of this work is to use the Karmarkar condition to investigate the charged anisotropic characteristics of compact stars in the recently proposed modified Ricci-inverse gravity. For this purpose, we derive the relativistic anisotropic static spherically symmetric solutions with specific Adler model for the 
metric potential. To determine the exterior geometry, we use the Bardeen model and carry out various physical tests to determine whether the Ricci-inverse gravity model is physically feasible, and to further investigate for energy density, pressure components, mass–radius relations, energy and equilibrium conditions. The success of Ricci-inverse gravity model for charged anisotropic compact stars is also discussed in our study. It is concluded that the existence of charged anisotropic compact stars is possible with our proposed 
gravity model. However, our chosen gravity model is not supporting massive stars. The exact limitations are not debated in this work; however, the stars with mass 
and radii (
, 9.10, 9.20, 9.30) are acceptable for our chosen model.
