Using the Comisso-Asenjo mechanism in the ZAMO frame, we derive the asymptotic hydrodynamic energy per unit enthalpy $\\epsilon^{\\infty}_\\pm$ and determine when reconnection outflows attained negative energy at infinity. By varying the spin $a$, electric and magnetic charges, NUT parameter $N_g$, and gauge coupling $g$, we compute the cutoff magnetization $\\sigma_0^{\\rm cutoff}$ and map the region of parameter space that admits $\\epsilon^{\\infty}_-<0$.
