In Sri Lankan tours, the first gadget you must carry around is your converting plug to Type D and Type G sockets. Variously, type D skid a track of three rounded pins out of a triangle pattern, while the type G three rectangular pins arranged in groups of three.
Sri Lanka's accommodation and most hotels have 220V-240V electric supply. Therefore, ensure that your units can handle this voltage.
