  Motivated by the experimental realization of a multi-channel charge Kondo
device [Iftikhar et al., Nature 526, 233 (2015)], we study generic charge and
heat transport properties of the charge two-channel Kondo model. We present a
comprehensive discussion of the out-of-equilibrium and time-dependent charge
transport, as well as thermal transport within linear response theory. The
transport properties are calculated at, and also in the vicinity of, the
exactly solvable Emery-Kivelson point, which has the form of a Majorana fermion
resonant level model. We focus on regimes where our solution gives exact
results for the physical quantum dot device, and highlight new predictions
relevant to future experiments.
