If your appliances are all multi voltage or dual voltage then you probably will just need plug adapters. We show the recommended plug adapters for all countries in the world in our World Electric Guide. Many U.S. electrical appliances are what they call "multi-voltage" or "dual-voltage".
Multi voltage means that the appliance will say somewhere on its body or on a charger “input 100-240 volts, 50/60 Hz...” or something very similar to that (it varies from manufacturer to manufacturer).
Dual voltage means that the appliance will say somewhere on its body or on a charger “input 125/250 volts, 50/60 Hz...” or something very similar to that (it varies from manufacturer to manufacturer). Some dual voltage appliances have small switches on them for switching from one voltage to another but many are self-sensing and the switching is automatic.
Some U.S. appliances that appear to be dual or multi voltage (from the input info provided) may not actually be rated for use outside of the U.S.. If you are not positive about the suitability of an appliance for use outside of the U.S. please be sure to contact the manufacture and have them verify its suitability
