We study the possibility of getting infinite energy in the center of mass frame of colliding charged particles in a general stationary charged black hole.
- For black holes with two-fold degenerate horizon, it is found that arbitrary high center-of-mass energy can be attained, provided that one of the particle has critical angular momentum or critical charge, and the remained parameters of particles and black holes satisfy certain restriction.
- For black holes with multiple-fold degenerate event horizons, the restriction is released.
- For non-degenerate black holes, the ultra-high center-of-mass is possible to be reached by invoking the multiple scattering mechanism.
