Antigua power converters - Do you need a power converter in Antigua?

What is a power converter for Antigua?

A power converter enables travellers to use their 100-120 volt electrical appliance with a 230 volt Antiguan 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 for Antigua?

A lightweight, cheap and small power adapter (or plug adapter) changes the shape of the plug on your device to fit into a power outlet found in Antigua, however an expensive and bulkier power converter [3] will transform the voltage of 230 volts from an Antiguan power outlet to work with a non-230 volt appliance.

Do I need a power converter for Antigua?

When you are travelling to Antigua from another region please ensure your device will accept a 230 volt power supply.

  • You will need a step down power converter [4] if you are visiting Antigua from a country that uses 100-120 volts and your device is incompatible with 230 volts. See our WikiConnections list of world power outlets guide to discover which voltage your country uses.
  • You shouldn't need a power converter if you are already using either a single voltage device that works with 230 volts or one that supports dual voltage.
  • Typically, devices which are designed to use a lower voltage such as 120 volts and then used in a 230 volt power outlet run a risk of an electrical fire hazard, blowing a 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 typically designed for international use and dual voltage, but please always check the device for dual voltage support first.
  • When powering appliances which draw more power or generate heat (for example clothes irons or hair straighteners) then you will need to use a bulkier higher wattage heavy duty power converter [5] to allow the appliance to be used with a 230 volt Antiguan power outlet.
  • It will be more cost effective to use a robust lightweight dual voltage travel appliance than carrying a much heavier high wattage power converter simply to use your existing domestic appliance.
  • For more information read our guides on using clothes irons, curling irons, hair straighteners and blow dryers in Antigua , along with recommendations for some affordable dual voltage alternatives.

Do I need a power converter for Antigua if I'm from the US?

The 230 volts used in a wall outlet in Antigua is different to a US supply so use a step down power converter [4] if your appliance or charger doesn't support dual voltage.

What converter do I need for Antigua?

If you need to use any 100, 110 or 120 volt appliance in Antigua you will need to use a step down power converter [4].

What voltage is used in Antigua?

Antigua uses 230 volts in their normal power outlets.

What is the difference between a transformer and a converter?

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 230 volts to 110 volts

  1. Use a step down power converter [4] to allow you to use a 110 or 120 volt appliance with an 230 volt Antiguan 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 Antigua before plugging that into an Antiguan 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 an 230 volt Antiguan power outlet.
How can you tell if you have a single voltage or dual voltage device?

How can you tell if you have a single voltage or dual voltage device?

The method to see if a appliance is dual voltage is to look for a sticker on the supplied power adapter or on the unit itself, typically on the rear of the device or near to where the power cord sits. The location will depend on the make and model of your device and could also state on the box.

  • Single voltage devices might have a specific number - such as 240V.
  • Single voltage devices could also say a small voltage range (around 20 volts) with a dash to accomodate small voltage fluctuations - such as 100-120V.
  • Dual voltage devices will typically say a larger range separated with a slash - such as 100/240V.

  3. Power converter - A step up step down power converter converts 110-120 volts up to 220-240 volts and 220-240 volts down to 110-120 Volts.
  4. Step down power converter - A step down power converter allows a 100-120 volt appliance to be used in a 220-240 volt power outlet.
  5. Heavy duty power converter - A 5000 watt heavy duty step up and step down power converter used to convert voltages for domestic appliances, power tools, televisions, heating appliances and motors.
