This research examines a non-extremal dyonic-like dilatonic charged black hole solution within a four-dimensional gravity model. The model includes two scalar (dilaton) fields and two Abelian vector fields, with interactions between them mediated by exponential terms involving two dilatonic coupling vectors. The solution is characterized by a dimensionless parameter a (where 0
