Every country is unique. Please review the voltage on your appliances and compare with the details listed below:
Mexico - plug type and voltage in Mexico are the same as in the U.S. and Canada (120V and 60Hz). If you are coming from US or Canada, you do not need an adapter or a converter.
Argentina - voltage in Argentina is 220V. If you are coming from US or Canada, you will need dual voltage appliances (or a converter) and an adapter.
France - voltage in France is 230V. If you are coming from US or Canada, you will need dual voltage appliances (or a converter) and an adapter.
Portugal - voltage in Portugal is 230V. If you are coming from US or Canada, you will need dual voltage appliances (or a converter) and an adapter.
If you use an appliance with a voltage that does not match the country's voltage you will blow a fuse and ruin your appliance. Check your appliance's voltage and make sure that it matches the country you are traveling to.
Pro packing tip: we recommend purchasing a Universal Adapter and dual voltage appliances, which will solve this problem for all of your travels around the world. See our founder's favorites here: https://www.wildterrains.com/laurens-picks
