We study a light-like charged collapsing shell in AdS-Reissner-Nordstromspacetime, investigating whether the corresponding Vaidya metric is supportedby matter that satisfies the null energy condition. We find that, if theabsolute value of the charge decreases during the collapse, energy conditionsare fulfilled everywhere in spacetime. On the other hand, if the absolute valueof the charge increases, the metric does not satisfy energy conditions in theIR region. Therefore, from the gauge/gravity perspective, this last case isonly useful to study the thermalization of the UV degrees of freedom. For allthese geometries, we probe the thermalization process with two pointcorrelators of charged operators, finding that the thermalization time growswith the charge of the operator, as well as with the dimension of space.
