What adapter do I need for Guinea-Bissau?

You'll need to pack a Type C plug adapter [3] for Guinea-Bissau if your plug doesn't fit into a Bissau-Guinean power outlet.

The type of plug adapter, converter or charger that you'll need to bring when visiting Guinea-Bissau all depends on the voltage and type of device that you're attempting to charge with a Bissau-Guinean power outlet. If you don't know which voltage your device uses then please read the section on how can you tell if you have a single voltage or dual voltage device first.

  • Be prepared for regular power blackouts and limited access to power in certain areas of Guinea-Bissau, it is advised to bring a power bank [4] if you wish to keep your phone battery charged whilst in a region without access to electricity or during a power cut.
  • If you are from the US and travelling to Guinea-Bissau then you will need to use a plug adapter for Guinea-Bissau to fit a US plug into a Bissau-Guinean power outlet.

type C socket power sockets are used in Guinea-Bissau. The power outlet can be recognised by 2 round holes adjacent to each other where the twin plug socket pins sit.

Do US plugs work in Guinea-Bissau?

No - an American plug won't work in Guinea-Bissau because it doesn't fit into a Bissau-Guinean power outlet without using a plug adapter. The voltage is 220 volts therefore you will need to use a power converter if your device isn't dual voltage and check that your appliance is compatible with a 50hz power outlet.

How do I use a 110 volt appliance in Guinea-Bissau?

A step down power converter will allow you to use a 110V appliance in a Bissau-Guinean power outlet.

What frequency is used in a Bissau-Guinean power outlet?

The frequency from a Bissau-Guinean power outlet is 50Hz.

Is the voltage in Guinea-Bissau the same as in the US?

The voltage which comes from a Bissau-Guinean power outlet is 220 volts, however Americans use 120 volts. If your US charger or appliance doesn't support dual voltage then you should use a power converter for Guinea-Bissau which allows a 120 volt US appliance to work with a 220-240 volt outlet.

Is a plug socket in Guinea-Bissau the same as in the US?

An American plug won't fit in a Bissau-Guinean power outlet therefore use a plug adapter for Guinea-Bissau. Both the voltage and frequency are different so if your charger or appliance isn't dual voltage you need to use a power converter for Guinea-Bissau and check that it works with a 50hz supply.

Does Guinea-Bissau have power outages?

Typically Guinea-Bissau suffers power blackouts several times every month and with this high level of unreliability it is recommended to prepare accordingly.

What proportion of Guinea-Bissau has access to electrical power?

Less than a quarter of the population of the country has access to electrical power.

Should I use a power bank in Guinea-Bissau?

Because electrical power isn't available in all areas of Guinea-Bissau alongside the lack of a reliable power grid, travellers are advised to use alternative charging options if they wish to continue charging devices such as cellphones or cameras.

  • During a trip to Guinea-Bissau increased use of smart phones for storing calendars, taking pictures, sat nav, social networks and playing games could syphon off power excessively. A flat smart phone battery can potentially leave you without sufficient power to make an emergency call or being able to use a satellite navigation app to find your way back to hotel or accommodation. Using a power bank [4] in Guinea-Bissau alleviates those concerns as it allows you to power up your cell phone without needing a Bissau-Guinean power outlet, especially when travelling to a country with limited access to power and power outages in some areas.
  • We recommend using at least a 10,000mAh portable charger [4] which can store enough power to cover around three full charging cycles whilst a 20,000mAh portable charger [14] should keep a typical cell phone charged for almost a week.
  • If you need to charge your laptop in Guinea-Bissau and your laptop has a USB-C charging port then bring a portable charger for a laptop [15] marked with PD (power delivery) and a model supplying at least 20 Wh.
  • Be aware that some airlines don't let you bring portable chargers on an aircraft with more than 100Wh of power and must be kept in hand luggage only so always ahead with the carrier first.
  • Average consumer power banks won't work with high wattage items, but a rechargeable hair dryer [12] or gas hair straighteners [13] are designed for travelling to locations with both power cuts and limited access to electricity such as Guinea-Bissau.
Should I use a power bank in Guinea-Bissau?
Will a solar battery charger work in Guinea-Bissau?

Solar backpacks are ideal in hot weather

Will a solar battery charger work in Guinea-Bissau?

The climate in Guinea-Bissau will be suitable enough to charge solar power bank [17] dependably, however it needs to be exposed to strong sunlight to produce suitable power for a single charge. It could prove inconvenient to continually unpack a solar power bank then wait whilst it recharges in sunny spells.

  • Instead, the bigger solar cells found on a solar backpack [16] give the backpack the ability to generate more power within a shorter period of time, meaning they should perform well in Guinea-Bissau.
  • A phone which has been plugged directly into a USB charging port of a backpack should gradually recharge the battery during sunny spells in Guinea-Bissau, but this could be inconvenient to have the phone continually connected in the bag if it is to be needed constantly. Unlike a handheld solar power bank which requires unpacking facing sunlight, a backback with solar panels is continuously exposed to daylight therefore can be powering up a regular power bank [4] during the day.
  • Even though the sunlight in Guinea-Bissau is strong, a bag should ideally have a solar cell efficiency of at least 22%, be able to generate a minimum of 6 watts of energy and includes a 10,000mAH power bank or stronger. The durable and flexible solar panels used in solar powered bags are made to survive scratches and bending, unlike regular solid solar panels. Solar bags are available in backpack, rucksack and messenger styles which makes them ideal for domestic, work and travel use.

Power converters for Guinea-Bissau enable travellers to use a 100-120 volt electrical device with a 220 volt Bissau-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?

An expensive and bulky power converter [18] transforms the voltage of 220 volts from a Bissau-Guinean power outlet to work with a non-220 volt appliance, whereas a smaller and more lightweight power adapter (or plug adapter) will change the shape of the plug on your appliance to fit into a power outlet found in Guinea-Bissau.

Do I need a power converter for Guinea-Bissau?

When travelling to Guinea-Bissau from a different region ensure that the device can be used with a 220 volt power supply.

  • A step down power converter [10] is needed if you are travelling from a country that uses 100-120 volts and your appliance isn't compatible with 220 volts. Read the list of world power outlets guide to discover the voltage your country uses.
  • You won't need a power converter if you are already using either a 220 volt single voltage device or one that is dual voltage.
  • Normally devices which are designed to work with a lower voltage (such as 120 volts) and then used in a 220 volt outlet run the potential risk of an electrical fire hazard, a blown fuse or damage to your device unless a step down power converter [10] is used.
  • You shouldn't need a converter if you wish to recharge a smaller electrical device such as a tablet or cell phone as these are typically support dual voltage and designed for international use, however you should always check the device for dual voltage support first.
  • When supplying power to appliances which draw more power or generate heat (such as hair straighteners or clothes irons) then you will need to use a more expensive higher wattage heavy duty power converter [19].
  • It should be more cost effective to purchase a robust lightweight dual voltage travel appliance than trying to carry a much heavier power converter in order to use your existing domestic appliance.
  • Read our comprehensive guides on travelling with curling wands, clothes irons, hair straighteners and hairdryers with Bissau-Guinean power outlets , along with recommendations on affordable dual voltage alternatives.

Do I need a power converter if I'm visiting Guinea-Bissau from the US?

The 220 volts used in a plug outlet in Guinea-Bissau is different to a 110 volt US supply so you need to bring a step down power converter if your charger or appliance doesn't support dual voltage.

What converter do I need for Guinea-Bissau?

If you need to use any 100-120 volt appliance with a 220 volt Bissau-Guinean power outlet you will need to use a step down power converter [10].

What voltage is used in Guinea-Bissau?

Guinea-Bissau uses 220 volts in their power outlets.

How to convert 220 volts to 110 volts

  1. Use a step down power converter [10] to allow you to use a 110 or 120 volt appliance with a 220 volt Bissau-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-Bissau before plugging that into a Bissau-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 Bissau-Guinean power outlet.
What is the difference between a transformer and a power converter?

Voltage converter

What is the difference between a transformer and a power 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.
What voltage is my device?

Single voltage hair dryer

What voltage is my device?

The best way to see if a device is dual voltage is to check for either a sticker or numbers printed on the charger or on the device itself, normally on the rear or near to where the power cord sits. The location might depend on the make or model of your appliance, it could also be written in the instruction manual.

  • Single voltage devices might have a specific number - such as 240V.
  • Single voltage devices might also have a small voltage range (20 volts difference) with a dash to accomodate small voltage fluctuations - such as 100-120V.
  • Dual voltage devices will typically say a larger voltage range separated with a slash - such as 110/240V.

Key to electrical adapter comparison

  1. Compatible number of countries based on data from the International Electrotechnical Commission World Plugs page (cited November 2018).
  2. Assuming only a single plug adapter from the plug adapter set will be used at any one time in a compatible location.
  3. Depending on if the power strip supports voltage conversion for low wattage items. All travel power strips tested do not convert voltage for high wattage appliances.
  4. Including the device itself, any supplied plug heads and power cords.
  5. Some travel power strips featuring less AC outlets may be small and lightweight enough to be suitable for hand luggage.
  6. Number of items if bringing an entire set of plug adapters for use in multiple locations to cover all eventualities (unless bringing only the necessary single plug adapter).

What type of adapter do you need for Guinea-Bissau?

Which type of adapter do I need for Guinea-Bissau?

The plug adapter or power converter that is suitable for Guinea-Bissau depends on various requirements, before choosing which adapter to bring we recommend using the following checklist:

How many electrical devices are you bringing to Guinea-Bissau?

Family may need to power devices too

How many electrical devices are you bringing to Guinea-Bissau?

  • List how many applicances and devices you intended on bringing with you to Guinea-Bissau (including tablets, laptops, cell phones, eReaders, hair straighteners and curling irons).
    • Take into account that you might own more electrical devices in the future. Are you thinking about buying a new laptop computer soon?
    • There is a growing number of USB powered rechargeable electronics such as electric shavers that utilise USB charging for their power source, the if you buy a new device it could use a USB power adapter so please check that your travel adapter has enough spare ports for these as well.
  • Are you also bringing family along who will need to charge their devices too?

Make a list of items to bring

What are the types of electrical devices do you need to charge with a Bissau-Guinean power outlet?

  • There are three types of electrical devices or appliances:
    • Low wattage electrical devices that can be plugged into a power outlet - for example a laptop.
    • High wattage appliances that can be plugged into an electrical outlet - for example clothes irons or hair straighteners.
    • USB powered electrical devices that connect to a USB port - for example mobile phones and iPads.
  • When you only intend to bring along just USB powered devices you'll find that a simple travel USB charger is perfect because you'll only have to pack that single compact charger rather than packing lots of domestic chargers.
  • Travel power strips are most suited for powering and converting voltage for multiple low wattage devices of any voltage, however unsuitable for high wattage appliances (such as hair straighteners) that need voltage conversion.

Do your appliances and devices work with a 220 volt power outlet?

How many power outlets will be available when you arrive in Guinea-Bissau?

Are multiple wall outlets available

How many power outlets will be available when you arrive in Guinea-Bissau?

  • Accommodation in Guinea-Bissau might offer only a single power outlet on the wall. This will present an issue when charging multiple items such as mobile phones, tablet computers and laptops overnight as you'll only be able to charge a single device at a time then have to swap every few hours.
  • If you need to recharge multiple devices simultaneously then we suggest bringing either a travel power strip or USB wall charger that are capable of charging multiple USB ports or power outlets.
Are you only planning on charging USB devices?

Are you only charging USB devices

Are you only planning on charging USB devices?

  • If you intend to bring USB devices such as mobile phones or cameras to use in Guinea-Bissau then it is recommended to just pack a travel USB wall charger.
  • If you only use a simple power plug adapter then you'll still need to pack your domestic USB power charger as well.

How much can you afford to pay?

  • A cheap power adapter starts from around under $10 USD (under £15 GBP / under C$45) to charge a single device from a Bissau-Guinean power outlet (providing that it is dual voltage or works with 220 volts) but investing in anywhere between $15 to $20 USD (£15-£20 GBP / C$25-C$30) means you can power more than one device at once and be able to use them in various different countries.

Do you plan to visit elsewhere in the future?

Do you plan on visiting countries other than Guinea-Bissau?

  • A simple power adapter only typically operates in the one country which it is made for, therefore if you want to travel to more than just one country then you'll need to carry additional plug adapters which in turn adds to the weight you'll have to carry.
  • Alternatively, travel USB wall chargers and universal travel adapters are made for going to more than one country becuase of their interchangeable heads.
How long will it take to get to Guinea-Bissau?

Arriving at an airport

How long will it take to get to Guinea-Bissau?

  • If you're embarking on a long flight to get to Guinea-Bissau consider bringing an airport-friendly power charger that can be used with different power outlet types, one which can be carried in hand luggage and can power phones and tablets before a long flight.
  • Not all airlines and airports actually have power outlets for customers so think about using a battery portable charger [4] which will recharge on the go. When arriving in Guinea-Bissau you could need to rely on a phone to make a telephone call, sending emails , using mapping or viewing an itinerary; please ensure that your phone will have ample power left.

Does the area of Guinea-Bissau you are staying in have good access to electrical power?

  • The power in Guinea-Bissau might occasionally fluctuate and this might cause damage to your devices, so it is advisable to use a power adapter which has surge protection such as a travel power strip.
  • Due to Guinea-Bissau having power cuts or having partial access to electricity you might find that whatever power adapter you use doesn't function anyway. Prepare for areas of limited electrical coverage and power cuts in Guinea-Bissau by using a solar backpack [16] or portable charger [4].
