Do I need a power converter for Saint Helena?

What is a power converter for a St Helenian power outlet?

Power converters for Saint Helena enable you to use a 100, 110 or 120 volt electric device with a 240 volt St Helenian power outlet.

Also known as: electrical converter, electrical transformer, voltage converter, power transformer or voltage transformer.

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

An expensive and heavy power converter [3] transforms the voltage of 240 volts from a St Helenian power outlet to work with a non-240 volt device, however a more lightweight and cheaper power adapter (or plug adapter) changes the shape of the plug on your device to fit into a power outlet found in Saint Helena.

Do I need a power converter for Saint Helena?

If travelling to Saint Helena from a different region check that the device will accept a 240 volt power supply.

  • A step down power converter [4] is needed if you are visiting Saint Helena from a country that uses 100-120 volts and your appliance is incompatible with 240 volts. Read our WikiConnections world power outlets guide to find out the voltage is used in your country.
  • You won't need a power converter if you already own either a single voltage device that works with 240 volts or one that is dual voltage.
  • Typically, devices which are designed to work with a lower voltage such as 120 volts and used with 240 volts run the potential risk of an electrical fire hazard, a blown fuse or damage to your device.
  • You won't need a converter if you are attempting to recharge a smaller electrical device such as a tablet as these are normally dual voltage and designed for international use, however you should always check the device for dual voltage support prior to your journey.
  • When powering appliances which draw more power or generate heat (for example hair straighteners and clothes irons) then you will need to use a much larger higher wattage heavy duty power converter [5] which allows it to be used with a 240 volt St Helenian power outlet.
  • Buying a smaller lightweight dual voltage travel appliance could be more cost effective and practical than investing in a heavier high wattage power converter in order to use your existing domestic appliance.
  • For more information read these comprehensive guides on travelling with clothes irons, curling irons, hairdryers and flat irons with St Helenian power outlets , along with advice for some affordable dual voltage alternatives.

Will I need a power converter if I'm visiting Saint Helena from America?

The voltage from a electric outlet in Saint Helena is different to a US supply so bring a step down power converter [4] if your appliance or charger isn't dual voltage.

What kind of converter do I need for Saint Helena?

You need a step down power converter [4] which will allow you to use any 100-120 volt appliance with a 240 volt St Helenian power outlet.

What is the difference between a converter and a transformer?

Converters and transformers are both used to change one voltage to another, but this ambiguity can cause confusion as their purposes are different:

  • Power converters are designed for simple electrical appliances which typically generate heat or use motors such as clothes irons, shavers or hair dryers. Transformers are designed for more complex electronic items such as televisions or games consoles.
  • Buying a power converter is cheaper than buying a power transformer.
  • Power transformers are larger and heavier making them more suited for permanent residential use; for example an expat wishing to use an imported television would need to use a transformer for this purpose.
  • Power converters are more suitable for travellers wishing to bring domestic appliances abroad such as hair dryers or flat irons. However, it is more practical and cost effective to purchase a dual voltage appliance designed for travel rather than a heavier power converter.
  • Power converters are suitable for 2 pin ungrounded appliances, it could be harder to find a converter if you want to use a grounded 3 pin appliance.
  • Transformers can be used constantly however it is recommended that converters are used for no longer than a couple of hours at a time.
  • Shops may sell transformers under the name of converters, for the purposes this guide we will be referring to both converters and transformers as converters.

How to convert 240 volts to 110 volts

  1. Use a step down power converter [4] to allow you to use a 110 or 120 volt appliance with a 240 volt St Helenian power outlet.
  2. If the power converter doesn't include the correct shaped plug then it will also be necessary to plug in the power cord from the power converter into a power adapter for Saint Helena before plugging that into a St Helenian power outlet.
  3. Some power converters include the ability to perform both step up and step down voltage conversions, therefore it may be necessary to manually switch the converter to output the voltage to the 110-120 volt range.
  4. Plug your appliance into the converter and turn the power on, your 110-120 volt appliance can now be used with a 240 volt St Helenian power outlet.

What voltage does Saint Helena use?

Saint Helena uses 240 volts in their power outlets.

Is my device single voltage or dual voltage?

Single voltage hair dryer

Is my device single voltage or dual voltage?

The easiest method to tell if your appliance is dual voltage is to look for either a sticker or numbers printed on the supplied power plug or on the appliance itself, normally near to where the power cord goes. This location will vary depending on the make and model of your device and could also state on the box or in the instruction manual.

  • Single voltage devices could have a specific number - such as 110V.
  • Single voltage devices might also have a small voltage range (20 volts difference) 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 100/240V.
