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. Because the voltage is different in Guinea-Bissau pack a power converter if your device isn't dual voltage and check that it is compatible with a 50hz power outlet.
  • If your device can run on 220 volts or is dual voltage and the plug will fit in a Bissau-Guinean power outlet then you can use it in Guinea-Bissau.
  • If your device can run on 220 volts or is dual voltage but the plug doesn't fit in a Bissau-Guinean power outlet you will need to bring a suitable plug adapter for Guinea-Bissau such a Type C plug adapter [3]. Please Note that a plug adapter for Guinea-Bissau (or power adapter) will change the shape of the plug on your device to fit into a plug outlet found in Guinea-Bissau, but isn't designed to convert the voltage from 220 volts to another voltage.
  • If your device doesn't run on 220 volts and isn't dual voltage then you'll also need a power converter for Guinea-Bissau to convert the voltage from 220 volts to the correct voltage for your device. You will still need to use a suitable plug adapter for Guinea-Bissau if your power converter doesn't have the correct Type C plug adapter.
  • If you need to power your USB devices such as mobile phones or tablets then a USB travel power adapter is suitable and it should be dual voltage, but ensure that you bring one which includes a Type C plug adapter otherwise you'll also need to use a suitable plug adapter for Guinea-Bissau.

Warning: If your device won't handle 220 volts you run the potential risk of blowing a fuse, damage to your device or even an electrical fire hazard. Before using your device in Guinea-Bissau read the instruction manual first to ensure safe operation.

  • Means lots of individual adapters to pack.
  • All remaining plug adapters will be useless using up space.
  • Not all plug adapter types are typically included (and especially the less common ones) - so ensure that your plug adapter set includes one which works in Guinea-Bissau.
  • A plug adapter only modifies the shape of the plug but not the voltage.
Voltage Converters

A voltage converter with surge protection

Voltage Converters

Those originating from the UK will not need a voltage converter as the voltage from a Bissau-Guinean power outlet is 220 volts.

Benefits of a voltage converter

Disadvantages of a voltage converter

  • Only changes the 220 volts in Guinea-Bissau and won't change the actual shape of the plug to fit in a Bissau-Guinean power outlet, therefore you'll still need to use a suitable plug adapter for Guinea-Bissau.
  • The size of most models makes them impractical for hand baggage.
  • An expensive converter won't be of any use after your visit to Guinea-Bissau.
  • It's often better value and more practical to purchase a dual voltage travel appliance than to purchase an expensive voltage converter simply in order to bring your existing single voltage domestic appliance abroad.

What plug sockets are used in Guinea-Bissau?

The type of power socket used in Guinea-Bissau is type C socket. You can recognise this power socket by two adjacent holes for live and neutral pins.

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 of the current from a Bissau-Guinean power outlet is 50 Hz.

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 for hot climates

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.

What is a USB travel power charger?

A USB travel charger is a dual voltage charger with interchangeable plugs and multiple USB ports, suitable for charging multiple USB powered devices when travelling abroad.

What USB charger do I need for Guinea-Bissau?

When you are travelling with more than one device the best international travel charger for Guinea-Bissau to buy is a multiple USB port charger which includes swappable plugs such as a 4 port USB travel charger [7]. Because these types of chargers are supplied with interchangeable pins and can handle from 100 to 240 volts it makes them ideal for over 100 countries around the world simply by changing the plugs over. If your device can support Fast Charge then you will benefit from much faster charging times with one of these types of power adapters plus additional compatibility with certain power hungry devices like tablets. This will allow you to charge multiple devices at the same time without needing to buy seperate travel adapters. By only needing a single lightweight travel charger will keep the overall weight down, making it ideal to store in hand baggage as well as being suitable for charging your devices at an airport or on the flight. Because of their versatility these types of power adapters can be used when you return home so when you're not on holiday they can be used overnight charging multiple tablets and smartphones with just a single plug socket.

If you travel to Guinea-Bissau we recommend buying this type of versatile travel charger at an electronics retailer. The travel adapter illustrated is the 4 Port USB Wall Charger [7] which has been tested successfully for powering multiple USB devices in numerous foreign countries on a daily basis.

What USB charger do I need for Guinea-Bissau?

Why use a travel USB charger for Guinea-Bissau?

  • Typically travel USB chargers include multiple USB charger ports, this means that you now only need to bring one charger to charge all your devices. It helps reduce the size and weight of your baggage by only packing one USB wall charger instead of bringing multiple power chargers with you.
  • All travel USB power chargers include swappable plug heads for various countries thereby making them perfect if visiting multiple countries which will probably use a different outlet to Guinea-Bissau.
  • Good USB travel chargers are rugged, lightweight and compact - ideal for the rigors of travel rather than risking packing a domestic charger which could be hard to repair or replace in Guinea-Bissau.
  • USB travel chargers will accept both the 220 volts used in Guinea-Bissau power outlets plus different voltage standards in other countries.
  • It's possible that hotels in Guinea-Bissau might only have a single power outlet, by using a travel charger with multiple USB ports means you can share the single wall outlet with family or other traveler instead of waiting to charge each device one by one.
  • Due to their versatile nature they take the worry out of visiting an unknown destination as they are guaranteed to work almost anywhere in the world.
  • Power outlets in airports are often scarce and the demand for charging multiple cell phones and tablets during departure can be high, so a USB charger with multiple ports and the capability to fast charge is ideal.
  • The power grid in some countries can be unstable, a good travel USB charger allows for unexpected surges to prevent damage to any devices attached to it. Trying to repair an overloaded smartphone or tablet in Guinea-Bissau might prove difficult and costly.
  • Higher priced USB travel chargers will also feature a power outlet strip to allow you to power low wattage devices such as laptops, but note these are unsuitable for high powered domestic such as hair dryers or clothes irons. For further information read the guide on using travel appliances in Guinea-Bissau for useful guidelines and advice on the best power adapter to use with a Bissau-Guinean power outlet for high powered appliances.
  • Some mobile phones and tablets could pull more than the normal 500 mA (milliamps) produced from a normal 5 volt USB power adapter to charge or provide fast charge. More expensive USB travel chargers will support fast charging incase any of your devices draw additional power.
  • Travel USB power chargers can also be useful when returning home by recharging multiple mobile phones and tablets every day using only one power outlet.

Power converters for Guinea-Bissau

What is a power converter for Guinea-Bissau?

A power converter allows travellers to use their 100, 110 or 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 visiting Guinea-Bissau from another country make sure that the device will accept a 220 volt power supply.

  • A step down power converter [10] is needed if you are travelling to Guinea-Bissau from a country that uses 100-120 volts and your appliance is incompatible with 220 volts. Read our list of world power outlets page to discover the voltage is used in your country.
  • You won't need a power converter if you already use either a 220 volt single voltage device or one that is dual voltage.
  • Devices which are designed to use a lower voltage (such as 110 volts) and then used in a 220 volt power outlet run the risk of an electrical fire hazard, a blown fuse or damage to your device.
  • You shouldn't need a power converter if you need to charge a smaller electrical device such as a tablet or mobile phone as these are normally designed for international use and dual voltage, however please always check the device for dual voltage support prior to your journey.
  • When powering appliances which draw more power or generate heat (such as hair dryers or clothes irons) then you will need to use a bulkier higher wattage heavy duty power converter [19].
  • It will be more cost effective to purchase a smaller robust dual voltage travel appliance than paying for a much heavier high wattage power converter just to use your existing domestic appliance.
  • For more information read our comprehensive travel guides on travelling with curling irons, clothes irons, hair dryers and hair straighteners in Guinea-Bissau , along with guides for affordable dual voltage alternatives.

What converter do I need for Guinea-Bissau?

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

What voltage is used in Guinea-Bissau?

Guinea-Bissau uses 220 volts in their standard 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 easiest way to tell if a device is single voltage or dual voltage is to look for either a sticker or numbers printed on the existing charger, or on the unit itself, normally on the rear or near to where the power cord goes. The location will depend on the make or model of your unit, it could also state in the instruction manual or on the box.

  • Single voltage devices might say a specific number - such as 240V.
  • Single voltage devices might also say 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 larger range separated with a slash - such as 110/240V.

Are you bringing more than one device

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 you need

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?

Will you only need 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 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 £15-£20 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?

Using a phone after a long haul flight

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].
