Adapters, Plugs, Outlets, and Voltage in Brazil 

In 2011, Brazil introduced a new round, three-prong outlet throughout the country (see image below).

In older buildings you can still find the older outlets (see image below), which are either two-prong and round or in the two-prong variant used in the USA.
European plugs will work with this type of outlet. However, the thicker European plugs, which are usually found on hair dryers and computers, will not.

The voltage can even vary within the same city. Therefore, in case of doubt it should always be reconfirmed whether the sockets in the respective accommodation work with 110V or 220V. Here is a list of the most commonly used voltages:
