Query: Regular Charged Black Holes, Quasilocal Energy and Energy Conditions   We revisit the relationship of inequality between the gravitational field
energy and the Komar charge, both quantities evaluated at the event horizon,
for static and spherically symmetric regular black hole solutions obtained with
nonlinear electrodynamics. We found a way to characterize these regular black
hole solutions by the energy conditions that they satisfy. In particular, we
show the relation between the direction of the inequality and the energy
condition that satisfy the regular black hole solutions.
