Abstract In this study, we investigate the properties of the Dyonic ModMax black hole solution using strong gravitational lensing. Additionally, we calculate the time delay between two relativistic images of a background object. First, we analyze expressions for the photon orbits in the spacetime of the Dyonic ModMax black hole. To obtain observational consequences, we provide expressions for the observable quantities, such as angular radius and magnifications. The numerous observations suggest that many nearby galaxies contain supermassive central black holes. In our model, such a supermassive black hole can be characterized by two additional parameters: γ and Q . Notably, the bending angle and the angular position decrease with increasing charge of the black hole Q , while the parameter γ displays opposite behavior to that of Q . By using observational data of supermassive black holes and , we obtain constraints for these parameters.
