  We investigate the three-dimensional behavior of gravity coupled to a
dynamical unit timelike vector: the aether, and present two new classes of
exact charged solutions. When c_{13}=0,\Lambda'=0$, we find the solutions is
the usual BTZ black hole but now with an universal horizon. In the frame of
black hole chemistry, we then calculate the temperature of the universal
horizons and, construct the Smarr formulas and first law in the three cases:
quasi-asymptotically flat, aether asymptotically flat and quasi-BTZ black hole
spacetime. We found these universal horizons obey an exact (or slightly
modified) first law of black hole mechanics and may have an entropy and, black
hole mass can be interpreted as enthalpy of spacetime. Then the holography may
be extended to these horizons under violating Lorentz symmetry.
