  k-Component q-deformed charge coherent states are constructed, their
(over)completeness proved and their generation explored. The q-deformed charge
coherent states and the even (odd) q-deformed charge coherent states are the
two special cases of them as k becomes 1 and 2, respectively. A D-algebra
realization of the SU$_q$(1,1) generators is given in terms of them. Their
nonclassical properties are studied and it is shown that for $k\geq3$, they
exhibit two-mode q-antibunching, but neither SU$_q$(1,1) squeezing, nor one- or
two-mode q-squeezing.
