Do I need a voltage converter for Saint Helena, Ascension and Tristan da Cunha?

The voltage used in Saint Helena, Ascension and Tristan da Cunha is 230V and the frequency is 50Hz. If this is the same in your own country, you don't need a voltage converter when travelling to Saint Helena, Ascension and Tristan da Cunha. If the voltage and/or frequency in your country is different, you should check if your devices are dual voltage. Nowadays, many electronic devices like hair styling tools or chargers for a laptop, phone, iPad, tablet or e-reader are dual voltage, but you should always double check this before using the device in another country.

You should be able to check the small print on a device or power adapter to see if it's dual voltage or not. If you see 100-240V 50/60Hz printed on the device or power adapter, it is dual voltage and will work with all voltages and frequencies used worldwide.

If your device or power adapter is not dual voltage or you are unsure, and the voltage and/or frequency in Saint Helena, Ascension and Tristan da Cunha differs from your own country, you should use a voltage converter when plugging in your devices and power adapters in Saint Helena, Ascension and Tristan da Cunha.

What's the difference between a travel adapter and a voltage converter?

A travel adapter is a device that allows you to plug your electronic devices into electrical outlets in foreign countries where the plug type is different. It does not change the voltage of the electricity.

A voltage converter, on the other hand, is a device that converts the voltage of the electricity from one level to another. It is necessary when you are traveling to a country with a different voltage than what your device is designed for. For example, if you are traveling from the United States (where the voltage is 110-120V) to Europe (where the voltage is 220-240V), you would need a voltage converter to use your 110V devices.

It is important to note that some electronic devices, such as laptops and smartphones, are dual voltage, which means they can handle both 110V and 220V. In this case, you would only need a travel adapter and not a voltage converter. It is always a good idea to check the voltage requirements of your electronic devices before travelling to a foreign country.

How do I know if my electrical device is dual voltage?

You should be able to check the small print on an electrical device or power adapter to see if it's dual voltage or not. If you see 100-240V 50/60Hz printed on the device or power adapter, it is dual voltage and will work with all voltages and frequencies used worldwide. If you can't find this information on the device or power adapter itself, you can maybe find it in the manual or by contacting the manufacturer of the device.

Can I charge my iPhone, Android phone or other smartphone in Saint Helena, Ascension and Tristan da Cunha?

Chargers for iPhones, Android phones and other smartphones or cell phones are usually dual voltage, so you can use them all over the world. However, it is possible you'll need an adapter to plug the charger into a Saint Helena, Ascension and Tristan da Cunha outlet.
