  We study (near-)circular orbits of charged particles in the background of
charged black holes in asymptotically Anti-de Sitter (AdS) spacetimes of
arbitrary dimensionality. We calculate the energy and angular momentum of such
particles in a large-radius limit. This allows us to compute the anomalous
dimension of the dual charged double-twist operators in a large-spin expansion,
making a prediction for the bootstrap analysis at large charge and spin. We
relate our result to the Weak Gravity Conjecture (WGC) for AdS black holes of
all sizes. We also discuss the relation of WGC with the existence of the
innermost stable circular orbit (ISCO) in any dimension.
