Following a theoretical proposal on multi-impurity charge Kondo circuits [T.K.T Nguyen and M.N. Kiselev, Phys. Rev. B97, 085403 (2018)] and the experimental breakthrough in fabrication of the two-site Kondo simulator [W. Pouse et al, Nat. Phys (2023)] we investigate a thermoelectric transport through a two-site charge Kondo quantum nano-device in the strong coupling operational regime. We focus on the fingerprints of the non-Fermi liquid and its manifestation in the charge and heat quantum transport. We construct a full fledged quantitative theory describing crossovers between different regimes of the multi-channel charge Kondo quantum circuits and discuss possible experimental realizations of the theory.
