I usually bring a 3 in one plug as well as both a folding charger that can charge my apple watch, iPhone and AirPods at the same time. I also bring a multi charging cable and a European adaptor/converter. On another subject, there aren't many drawers on Solstice Class ships but there is a large cabinet over the bed. I bring these folding boxes to put clothes in where weight restrictions on airplanes allow me to carry the extra weight.
