Using the Wald formalism, we investigate the thermodynamics of charged black holes in the Einstein-\ae ther-Maxwell theory, considering both universal and Killing horizons. In particular, by aid of a scaling symmetry of the action, we obtain the Smarr integral formula. Assuming the canonical form, $M = 2TS + Q\Phi$, we find that the entropy in general takes a very complicated form, and is a function of various parameters. Only in very particular cases, it is given by one fourth of the area of the horizon.
