Check the markings on the device before traveling. Each electrical device has a label (often on the charger) stating at which volt range and frequency it works - example “INPUT: 100-240V, 50/60 Hz”. If this range is also in the target country, you do not need a voltage converter, just check the type of socket / plug. More information about the voltage converter can be found here.
