We investigate regular rotating black holes predicted by asymptotically safe gravity, where the Newton constant varies with energy scale and modifies the near horizon geometry. These solutions remain asymptotically flat and avoid central singularities while differing from the classical Kerr spacetime in the strong field region. We compute the radiative efficiency of thin accretion disks and the jet power from the Blandford Znajek mechanism, both of which depend on the deformation parameter of the model. The predictions are compared with observational estimates for six stellar mass black holes. For systems with low or moderate spin the model reproduces the data within reported uncertainties, while rapidly spinning sources such as GRS 1915 105 present tensions and point to a restricted deformation range or the need for additional physics. The results show that quantum corrections confined to the strong gravity regime can still leave detectable imprints on high energy astrophysical processes. Radiative and jet based diagnostics therefore provide a promising method to test the geometry near the horizon and to explore possible signatures of quantum gravity in observations.
