Main Voltage in Sao Tome and Principe

Do I Need a Voltage Converter in Sao Tome and Principe?

Sao Tome and Principe runs on a main voltage of 220 volts at a frequency of 50 Hz. This is effectively the same as India's 230V/50Hz. You can plug any Indian device into a Sao Tome and Principe socket without a voltage converter, as long as the plug shape fits.

Will my Indian charger work in Sao Tome and Principe?

Yes, but it depends on which socket your hotel has. Sao Tome and Principe uses Type C and F sockets at 220V/50Hz. Your Indian phone and laptop chargers are dual-voltage (the label reads 100–240V), so they handle Sao Tome and Principe voltage without any issue. The only question is plug shape — your Indian plug fits Type C sockets directly, but will not fit Type F sockets without an adapter. You do not need a voltage converter — Sao Tome and Principe's 220V is the same as India's 230V.
