Electricity and plugs

March 15, 2007 | By More

Two different voltages are in use in Brazil: 127V (popularly referred to as 110V; there is no significant difference between the two values) and 220V. The geographical distribution of both is quite arbitrary. Most of the states of Rio and São Paulo use 127V, but there are exceptions. Top-class hotels will offer 220V as well.

The frequency is 60Hz.


110 V: Arraial do Cabo, Belém, Búzios, Cabo Frio, Recife, Salvador, São Paulo (capital), Rio de Janeiro (capital)

220 V: Arraial d’Ajuda, Bombas, Bombinhas, Camboriu, Ferrugem, Florianópolis, Fernando de Noronha, Fortaleza, Garopaba, Maragogi, Morro de São Paulo, Natal, Porto de Galinhas, Porto Seguro

From a practical point of view, the 127V voltage is not a threat to mobile phone/digital camera/mp3 player and laptop chargers. Modern chargers are designed to work with different voltages.

There are three types of plugs:

– the most common one is the round one with two pins:

plain with two pins:

plain with three pins, used mainly for washing machines and other electric appliances that need earth/ground.
