The European plug fits into this socket. The "thicker" plug, which is usually found in hairdryers and computers, however, do not fit.

The "thicker" plug does not fit in those either. You will definitely need an adapter for this socket.
Warning: The electrical voltage can be either 110V or 220V, depending on the region in Brazil.
