An accurate boost factor is required to estimate the energy injection from dark matter annihilation, which may affect the cosmological re-ionization process. We combined various box-size simulations (side lengths of $1 \\, {\\rm kpc}$-$10 \\, {\\rm Mpc}$) to cover a wide range of scales, i.e. $k=1$-$10^7 \\, {\\rm Mpc}^{-1}$.
