1. A sanitization system for an aircraft, the sanitization system comprising:
a power source; and
a plurality of passenger service units, each of the plurality of passenger service units comprising:
a sanitizer in electrical communication with the power source, the sanitizer configured to emit ultraviolet radiation having an average wavelength between 200 and 230 nm, the power source configured to provide power to the sanitizer of a first passenger service unit and subsequently to the sanitizer of a second passenger service unit during an occupied flight of the aircraft; and
an energy storage device in electrical communication with the power source and the sanitizer, the energy storage device configured to charge during the occupied flight; and
a controller in operable communication with the sanitizer of each of the plurality of passenger service units, the controller configured to:
command the power source to provide power to the sanitizer of each of the plurality of passenger service units in a successive order during the occupied flight of the aircraft;
command the power source to trickle charge the energy storage device of each of the plurality of passenger service units simultaneously with powering each of the plurality of the sanitizer in the successive order;
verify an occupancy of the aircraft is empty after the occupied flight, and
in response to determining the energy storage device of each of the plurality of passenger service units is charged, commanding the energy storage device of each of the plurality of passenger service units to power all of the sanitizer from the plurality of passenger service units simultaneously.
