Trying to figure out what you need in order to make your electrical appliances work overseas can be a little confusing. But never fear. We here at Le TRAVEL STORE have put together this guide to help you figure out exactly what you need.
The electricity coming out of the wall in the USA is 110 volts. In most other countries it is 220 volts. This means that you either need a voltage converter, or an appliance that accepts both 110v and 220v – appliances that accept both are said to be dual voltage.
Most countries also use a different plug shape than the USA. In order to make your plug fit in the wall,
A few other countries use 110v, meaning you can just plug your US appliance right in. These countries include Japan, Brazil, Canada, Mexico, and many places in the Carribean, Central America, and the Pacific Islands.
