The existence and stability of vector solitons in non-parity-time (PT)-symmetric complex potentials are investigated. We study the vector soliton family, in which the propagation constants of the two components are different. It is found that vector solitons can be stable below and above the phase transition of the non-PT-symmetric complex potentials. Below the phase transition, vector solitons are stable in the low power region. Above the phase transition, there are two continuous stable intervals in the existence region. The profiles of two components of these vector solitons show the asymmetry and we also study the transverse power flow in the two components of these vector solitons in the non-PT-symmetric complex potentials.
