We consider a black hole with quasi-topological electromagnetism to explore the chaos behavior of particle motion near the black hole. We first study the static equilibrium of charged particle near the horizon to verify the chaos bound. The chaos bound could be violated in the higher order expansion of metric function and electric potential function. Then we study the relationship between the ``maximal'' Lyapunov exponent $\lambda_s$ defined by static equilibrium and the Lyapunov exponent of the particle geodesic motion near the Reissner-Nordstr$\rm\ddot{o}$m(RN) black hole and the black hole with quasi-topological electromagnetism. We find an interesting relationship between the Lyapunov exponent $\lambda_{ph}$ of photon's radial falling into the black hole and the ``maximal'' Lyapunov exponent $\lambda_s$. For the black hole whose metric function increases monotonically with radius outside horizon, they satisfy the relation $\lambda_{ph} \geq 2\lambda_s$.
