Good question Didier! You would first need to determine what type of outlets and voltages are available in whatever country you intend to use the appliances. An adapter may be necessary for the units to be able to function. The other concern, with taking a US model to another country, is that the manufacturer's warranty is for service within the US. On the rare chance that you might need repairs, you would need to bring the appliance back to the US. ^Jecca
