Abstract: The $p$-wave and $p+ip$-wave holographic superconductors with fixed DC supercurrent are studied by introducing a nonvanishing vector potential. We find that close to the critical temperature ${T}_{c}$ of zero current, the numerical results of both the $p$-wave model and the $p+ip$ model are the same as those of Ginzburg-Landau (GL) theory; for example, the critical current is ${j}_{c}\ensuremath{\sim}({T}_{c}\ensuremath{-}T{)}^{3/2}$ and the phase transition in the presence of a DC current is a first-order transition. Beside the similar results between both models, the $p+ip$ superconductor shows isotropic behavior for the supercurrent, while the $p$-wave superconductor shows anisotropic behavior for the supercurrent.
