  Supersymmetric models with sub-TeV charginos and sleptons have been a
candidate for the origin of the long-standing discrepancy in the muon anomalous
magnetic moment (g-2). By gathering all the available LHC Run 2 results, we
investigate the latest LHC constraints on models that explain the anomaly by
their chargino contribution to the muon g-2. It is shown that the parameter
regions where sleptons are lighter than charginos are strongly disfavored. In
contrast, we find that the models with $m_{\tilde{\mu}_{\mathrm L}}\gtrsim
m_{{\tilde\chi}^{\pm}_1}$ are still widely allowed, where the lighter chargino
dominantly decays into a W-boson and a neutralino.
