We relate across dimensions BPS attractors of black strings and black holesof various topology in gauged supergravities with nontrivial scalar potential.The attractors are of the form AdS$_{2, 3} \times \Sigma^{2, 3}$ in 4, 5, and 6dimensions, and can be generalized to some higher dimensional analogs. Eventhough the attractor geometries admit standard Kaluza-Klein and Scherk-Schwarzreductions, their asymptotic AdS spaces in general do not. The resulting lowerdimensional objects are black holes with runaway asymptotics in supergravitytheories with no maximally symmetric vacua. Such classes of solutions arealready known to exist in literature, and results here suggest aninterpretation in terms of their higher-dimensional origin that often has afull string theory embedding. In a particular relevant example, the relationbetween 5d Benini-Bobev black strings arXiv:1302.4451 and a class of 4dCacciatori-Klemm black holes arXiv:0911.4926 is worked out in full detail,providing a type IIB and dual field theory description of the latter solutions.As a consistency check, the Cardy formula for the field theory is shown tomatch the Bekenstein-Hawking entropy for horizon topology of any genus.
