Sao Tome power outlet

Summary

The type of plug adapter, power converter or charger that you'll need when visiting Sao Tome all depends on the voltage and type of device that you're attempting to charge with a Sao Tome power outlet. If you don't know what voltage your device uses then read the section below about how to find out the voltage of your device before going any further.

  • If your device is 220 volts or is dual voltage and the plug can fit in a Sao Tome power outlet then it will work in Sao Tome.
  • If your device can run on 220 volts or is dual voltage but the plug won't fit in a Sao Tome power outlet you'll need to bring a suitable plug adapter for Sao Tome such a Type F plug adapter [2]. A plug adapter for Sao Tome (or power adapter) is designed to change the actual shape of the plug on your device to fit into a plug outlet found in Sao Tome, but won't change the voltage from 220 volts to a different voltage.
  • If your device doesn't run on 220 volts and isn't dual voltage then you will also need a power converter for Sao Tome to convert the voltage from 220 volts to the correct voltage for your device. You will still need to use a suitable plug adapter for Sao Tome if the power converter doesn't have the correct Type F plug adapter.
  • If you only need to power one or more USB devices such as a mobile phone or tablet then a USB travel power adapter is suitable and it should work with any voltage, but ensure that you bring a USB travel adapter which includes a Type F plug adapter otherwise you will still need to bring a suitable plug adapter for Sao Tome.

Warning: If your device won't handle 220 volts you run the risk of blowing a fuse, damage to your device or even an electrical fire hazard. Prior to using your device in Sao Tome check the instruction manual first to ensure safe operation.

What USB charger do I need for Sao Tome?

If you are travelling to more than one country then the best international travel charger for Sao Tome to buy is a multiple USB charger which includes compatible plugs such as a 4 port USB travel charger [5]. There are two types of power outlets in Sao Tome (types F and C) and bringing this ensures that you are covered for type C. As these types of chargers are supplied with interchangeable pins and can handle from 100 - 240 volts will mean that you can travel to multiple countries in Europe, Asia, North America and Africa simply by switching the included heads. If your type of device can support Fast Charge then you will benefit from much faster charging times with one of these types of USB power chargers, and support for more power hungry devices.

Unlike other travel chargers this means you can recharge multiple devices at once without needing to buy multiple power chargers. By only packing a single international travel charger will help keep the overall size and weight down, making it perfect to fold up and store in hand luggage and convenient for charging your devices at the airport or on a flight. Because of their flexibility these types of power chargers can be used when back at home as well as abroad so when you're not on holiday they can sit under your bedside table charging multiple phones and tablets using just a single plug socket.

Why use a travel USB charger for Sao Tome?

  • Normal travel USB chargers include multiple USB charger ports, meaning you now only need to bring a single charger to charge multiple devices. Rather than bring 4 separate power chargers you only need to pack a single 4 port USB wall charger to power up to 4 individual devices, thereby reducing the weight of your baggage.
  • Travel USB chargers should include swappable plug heads for different regions thereby making them perfect if visiting different countries across Africa which will probably use different power outlets to Sao Tome.
  • A good power charger is lightweight, compact and rugged - perfect for the rigors of travel rather than risking packing a domestic charger which could be hard to repair in Sao Tome.
  • USB travel chargers can accept the 220 volt power outlets in Sao Tome along with different voltage standards across the world.
  • There is a possibility that hotel rooms in Sao Tome might only have a single power outlet, by bringing a travel charger with multiple USB ports means you can share the single wall outlet with family or other traveler rather than waiting to charge one device at a time.
  • Because of their flexible nature a travel USB charger takes the uncertainty out of travelling to an unknown country as they are guaranteed to work practically anywhere on the planet.
  • Power outlets in airports are often in short supply and the demand for charging multiple cell phones and tablets before a flight can be high, therefore a USB travel charger with multiple ports and the ability to fast charge is perect.
  • The power grid in some countries can be unstable, a quality travel USB charger allows for unexpected fluctuations and will prevent damage to any devices attached to it. Trying to repair an overloaded mobile phone or tablet in Sao Tome might prove inconvenient and costly.
  • More expensive USB chargers will also include power outlet strips to plug in multiple low powered devices such as laptops, but please be aware these will be unsuitable for high powered appliances such as hair dryers or clothes irons. For further information read our guide on using travel appliances with a Sao Tome power outlet for guidelines on the most suitable power adapter to use with a Sao Tome power outlet for high wattage devices.
  • Certain mobile phones and tablets could pull more than the standard 500 milliamps produced from a standard 5 volt USB adapter to charge or provide fast charge. Ensure that the USB power adapter can support fast charging should some of your devices require extra power.
  • When back at home travel USB chargers can still be useful by recharging multiple mobile phones on a daily basis using one power outlet.

Voltage converter

What is the difference between a power converter and a plug adapter?

A heavy and bulky power converter [7] converts a 220 volt Sao Tome power outlet to work with a non-220 volt device, but a more lightweight and cheaper power adapter [6] (or plug adapter) changes the shape of the plug on your device to fit into a power outlet in Sao Tome.

Do I need a power converter for Sao Tome?

If travelling to Sao Tome from a different region ensure the device can be used with a 220v supply.

  • If charging a USB device which originated in a country which uses a lower voltage (for example 110 volts) check your device is dual-voltage (indicated by 100-240 volts) otherwise you may need to use an additional International travel voltage converter [9] to prevent the device from overheating when charging it.
  • When powering larger appliances if you are traveling to Sao Tome from a lower 110 volt location you will need to use a much larger Step Down Voltage Converter [8] to convert the voltage from 110 volts to 220 volts.

See the list of world power outlets page to find out which voltage your country uses.

How can I tell if I have a dual voltage or single voltage appliance?

Dual voltage hair dryer

How can I tell if I have a dual voltage or single voltage appliance?

A simple method to tell if your appliance is dual voltage is to check for a sticker on the charger or on the unit itself, normally near to where the power cord goes. This location will vary depending on the make and model of your appliance but could also be written on the box.

  • Single voltage devices might have a specific number - such as 240V.
  • Single voltage devices might also say a small voltage range (20 volts diffence) with a dash to accomodate small voltage fluctuations - such as 220-240V.
  • Dual voltage devices will say a large range separated with a slash - such as 110/240V.
