  Electroweak-inos, superpartners of the electroweak gauge and Higgs bosons,
play a special role in supersymmetric theories. Their intricate mixing into
chargino and neutralino mass eigenstates leads to a rich phenomenology, which
makes it difficult to derive generic limits from LHC data. In this paper, we
present a global analysis of LHC constraints for promptly decaying
electroweak-inos in the context of the minimal supersymmetric standard model,
exploiting the SModelS software package. Combining up to 16 ATLAS and CMS
searches for which electroweak-ino efficiency maps are available in SModelS, we
study which combinations maximise the sensitivity in different regions of the
parameter space, how fluctuations in the data in individual analyses influence
the global likelihood, and what is the resulting exclusion power of the
combination compared to the analysis-by-analysis approach.
