San Tome & Principe is located in Central Africa.  When traveling to San Tome & Principe it is important to take along the correct adapter plug for your trip. 

Adapter plugs allow electrical connections up to 240 volts. An adapter plug does NOT change the current or voltage (this requires a converter) unless your appliance is dual voltage. Check to make sure your hair dryer, curling iron, electric razor and other appliances are dual voltage before you leave on your trip.  Non-grounded adapters may NOT be used with appliances that have grounded plugs; for these you will need a grounded adapter.

Many of our customers find it handy to have multiple adaptors while traveling - either to run several appliances simultaneously or simply as a backup.

Grounded Adapter Plugs

If you are traveling with a grounded United States dual/multi-voltage appliance or using a grounded Transformer you will need to use a grounded adapter plug. A grounded United States plug has two flat blades and one round pin.

Why do I need a North American adapter?

Even though Japan uses North American sockets, the sockets are not required to be polarized. Since devices such as laptops have a polarized plug with one prong wider than the other, you will still need an adapter to use your plug in Japan.

An adapter plug does NOT change the current or voltage (this requires a converter).

Cycles: 50 Hz vs. 60 Hz.

San Tome & Principe operates on 220 volt electricity and is generated at 50Hz (Cycles) Alternating Current. United States 110-120 volt electricity is generated at 60Hz (Cycles) Alternating Current. This difference in cycles may cause the motor in your 60Hz United States appliance to operate slightly slower when used on 50Hz foreign electricity. Most modern electronic equipment including battery chargers, computers, iPods, etc., will not be affected by the difference in cycle.

Computers and Apple Products

If you are traveling overseas with a Toshiba, HP, Lenovo, Asus, laptop or Apple device such as an iPad, chances are you won’t need a voltage converter. Most laptops are multi-voltage and will operate on voltages ranging from 100 to 240 volts. However, computers do need to make safe connections to foreign power systems and a surge protector is recommended and you will still need an adapter to use your plug.
