  We numerically simulate collisions of charged shockwaves in Einstein-Maxwell
theory in anti-de Sitter space as a toy model of heavy ion collisions with
non-zero baryon charge. The stress tensor and the baryon current become well
described by charged hydrodynamics at roughly the same time. The effect of the
charge density on generic observables is typically no larger than 15\%. %The
rapidity profile of the charge is wider than the profile of the local energy
density. We find significant stopping of the baryon charge and compare our
results with those in heavy ion collision experiments.
