For ???????? ????? ????????historical reasons, electrical voltage is not the same all throughout Brazil. This fact  may cause a bit of confusion to those just arriving, so we’d like to provide an overview of what you’re likely to encounter in more popular destinations.

Although most modern devices will work with any voltage from 90V to 230V AC, if you have some specialized device you better watch or the supply could get damaged.

All of Brazil is standard 60 Hz AC and voltage may vary from 110 V, to 127 V to 220V.

Belo Horizonte is 110V

Brazil’s Capital, Brasilia is 220V

Buzios, RJ : 110V

Corumbá, MS 110 V AC

Curitiba 110V

Florianopolis: 220V

Maceió, AL : 220V

Manaus 127 V AC

Natal, Rio Grande do Norte 220V

Porto Alegre, far south of Brazil 110V

Rio de Janeiro 110 V

Salvador, Bahia : 110V

São Paulo – you’ll find both voltages, you should ask when arriving at your hotel. Can be 110 or 220V AC. Most hotels have 110V outlets along with 220V for your commodity.

If you are traveling to deep country like Amazon regions or internal Goiás, Minas Gerais and elsewhere you may find unstable electricity at times(from personal experience).
