Power converters for Guinea

What does a power converter for Guinea do?

A power converter for Guinea will allow travellers to use their 100, 110 or 120 volt electric appliance with a 220 volt Guinean power outlet.

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

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

A cheap, small and lightweight power adapter (or plug adapter) will change the shape of the plug on your device to fit into a power outlet in Guinea, but an expensive and bulkier power converter [3] converts the voltage of 220 volts from a Guinean power outlet to work with a non-220 volt device.

Do I need a power converter for Guinea?

If visiting Guinea from a different country please check the device can be used with a 220 volt power supply.

  • A step down power converter [4] is needed if you are visiting Guinea from a country that uses 100-120 volts and your device or appliance is incompatible with 220 volts. Read our list of world power outlets guide to see which voltage is used in your country.
  • You don't need a power converter if you already own either a single voltage appliance that works with 220 volts or one that is dual voltage.
  • Typically, electrical devices designed for a lower voltage (such as 120 volts) and then used with 220 volts run a risk of an electrical fire hazard, a blown fuse or damage to your device unless a step down power converter [4] is used.
  • You won't need a power converter if you wish to charge a smaller electrical device such as a tablet as these are normally designed for international use and support dual voltage, however you should always check the device for dual voltage support first.
  • For supplying power to high wattage appliances or generate heat (for example clothes irons or hair dryers) then you will need to use a much larger higher wattage heavy duty power converter [5] which allows the appliance to be used with a 220 volt Guinean power outlet.
  • It will be more cost effective to purchase a robust lightweight dual voltage travel appliance than bringing a heavier high wattage power converter to Guinea simply to use your existing domestic appliance.
  • Read these comprehensive guides on how to use curling irons, clothes irons, hair dryers and hair straighteners in Guinean power outlets , along with recommendations on some affordable dual voltage alternatives.

Will I need a power converter for Guinea if I'm visiting from America?

The 220 volts from a power outlet in Guinea is different to a 110 volt US outlet, therefore you need to use a step down power converter [4] if your charger or appliance doesn't support dual voltage.

What converter do I need for Guinea?

To use any 100, 110 or 120 volt appliance with a 220 volt Guinean power outlet you will need to buy a step down power converter [4].

What voltage does Guinea use?

Guinea uses 220 volts in their normal power outlets.

How to convert 220 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 220 volt Guinean 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 Guinea before plugging that into a Guinean 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 220 volt Guinean power outlet.

What is the difference between a converter and a power 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.

What voltage is my device?

One method to see if your appliance is either single or dual voltage is to check for numbers printed on the supplied charger, or on the device itself, normally near to where the power cord sits. This location will depend on the make or model of your device but should also be written in the instruction manual or on the box.

  • Single voltage devices might have a specific number - such as 120V.
  • Single voltage devices might also have a small voltage range (around 20 volts) with a dash to accomodate small voltage fluctuations - such as 220-240V.
  • Dual voltage devices will say a larger voltage range separated with a slash - such as 110/240V.

  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.
