UK to Greenland power adapters - what kind of power adapter is needed for Greenland?

Greenlandic power outlet

What adapter do I need for Greenland?

You'll need to bring a Type E plug adapter to Greenland if the plug you need to use doesn't fit in a Greenlandic power outlet.

The type of power adapter, converter or charger that you'll need to use when visiting Greenland all depends on the voltage and type of device that you're trying to use with a Greenlandic power outlet. If you do not know what voltage your device uses then please read the section below on how can you tell if you have a single voltage or dual voltage device first.

  • If you're from the US and travelling to Greenland then you will need to use a plug adapter for Greenland to fit a US plug into a Greenlandic power outlet. As the voltage is different in Greenland pack a power converter for Greenland if your device isn't dual voltage and check that it can work with a 50hz power outlet.
  • If your device can run on 220 volts or is dual voltage and your plug will fit in a Greenlandic power outlet then you can use it in Greenland.
  • If your device can run on 220 volts or is dual voltage but the plug doesn't fit in a Greenlandic power outlet you will need a suitable plug adapter for Greenland such a Type E plug adapter. Please Note that a plug adapter for Greenland (or power adapter) only changes the shape of the plug on your device to fit into a plug outlet found in Greenland, but doesn't convert the voltage from 220 volts to a different voltage.
  • If your device is unable to run on 220 volts and isn't dual voltage then you will also need a power converter for Greenland to convert the voltage from 220 volts to the correct voltage on your device. You will still need to pack a suitable plug adapter for Greenland if your power converter doesn't use the correct Type E plug adapter.
  • If you simply want to bring USB devices such as a tablet or mobile phone then a USB travel power adapter is suitable and it will work with any voltage, however make sure that you choose to bring a USB travel adapter which includes a Type E plug adapter otherwise you will still need to bring along a suitable plug adapter for Greenland[3] [AD]
  • Excessive use of a mobile phone during a trip to Greenland will leave you with a flat battery quickly, it is practical to bring a power bank if you want to recharge your mobile phone or other USB powered devices whilst travelling to an unknown country.

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

Where to buy a power adapter in Greenland

Arriving at an airport

Where to buy a power adapter in Greenland

On arrival power adapters could be found in local electrical high street shops and drug stores, but always check the build quality first as safety standards might be different in a foreign country as this is important when dealing with electrical goods. Keep in mind that a shopping trip searching for power adapters in an unknown location might be impractical, especially as this needs to happen quickly before batteries run out.

Hotel receptions could have a power adapter for sale, hire or as a complimentary extra for guests; however, availability is normally limited and a hotel might not have the exact type required for your country. If in doubt, call ahead to the hotel first and request a reservation as it is unlikely that an adapter will be found in your room on arrival.

Where to buy a power adapter for Greenland in the UK

Greenland to UK power adapters will most likely be available to buy in the UK from airports such as Heathrow, Gatwick, Manchester, Stansted, Luton, Edinburgh, Glasgow and Birmingham prior to departure, however the range of adapters might be limited to popular destinations. It is recommended to research the exact type of adapter required prior to shopping at the airport. Look in the travel accessories section of airport newsagents, electronic stores and pharmacists such as WH Smith, Dixons or Boots but expect to pay 50% more than regular prices.

It will be more convenient and cheaper to buy the correct power adapter in advance of your trip. UK high street electrical shops, newsagents and chemists such as Currys PC World, WH Smith or Boots normally typically only sell popular types of travel adapters covering a limited number of countries however for widest choice it is recommended to buy a power adapter online. In January 2019 we checked 2 high street branches of WH Smiths without seeing any power adapters available to purchase and 1 branch of Boots only had a pack of European adapters available.

Greenland power outlets and plug sockets

What plug sockets are used in Greenland?

There are four different types of power supply used in Greenland, types E, C, F and K with the primary power supply being type E:

  • Plug Type C - This ungrounded power socket, also called the type C socket or Europlug, can be identified by the two holes adjacent to each other.
  • Plug Type E - The round plug outlet (technically called a CEE 7/7 plug) can be identified by the two large adjacent holes along with one long metal earth pin protruding in the top to form a triangular configuration.
  • Plug Type F - You can recognise this power socket by two large round adjacent holes where the twin pins go along with a pair of thin metal grounding clips above and below.
  • Plug Type K - You can identify the power outlet by the 3 large holes forming an inverted triangular shape for live, neutral and earth pins. [3] [AD]

How do I use a 110 volt appliance in Greenland?

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

What electrical frequency is used in Greenland?

The frequency of the current used in a Greenlandic power outlet is 50 Hz. [11]

https://en.wikipedia.org/wiki/Mains_electricity_by_country

Is there good access to electricity in Greenland?

Greenland has excellent access to electricity throughout the country.

Is the power grid reliable in Greenland?

Though consistent electrical power can't be guaranteed, the power grid in Greenland is classed as dependable and there is no history of persistent power cuts compared to other countries.

Should I pack a portable charger for Greenland?

USB power bank for charging phones

Should I pack a portable charger for Greenland?

Even though power blackouts in Greenland aren't common and electricity is available to the entire population, travellers should still bring a portable charger to recharge their cell phone and other devices.

  • During a trip increased use of cell phones for storing calendars, taking photos, GPS, social networks and streaming videos will drain the power before the end of the day. As well as the simple missing photograph opportunities a flat cell phone battery could potentially leave you stranded without enough power to make emergency calls or being able to use a GPS app to return back to your accommodation.
  • Bringing a power bank to Greenland eases those concerns as it means you can recharge your smart phone without needing a wall charger.
  • A 10,000mAh portable charger can supply enough electricity to cover over 3 full days of mobile phone use while a 20,000mAh power bank should keep an average smart phone powered for roughly a week depending on the usage and model of the phone. The mAh rating (milli ampere-hours) shows the capacity of the battery and gives an indication of the number of charges the portable charger is capable of.
  • If you want to charge your laptop and it it supports USB-C charging then look for a portable charger for a laptop marked with PD (power delivery) which supplies at least 20 Wh.
  • Please note 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.
  • Normal consumer portable chargers aren't strong enough for use with high wattage items that generate heat, but a rechargeable hair dryer or gas hair straighteners are designed for travelling.    [4] [12] [13] [14] [15] [16] [AD]
Does a solar powered charger work in Greenland?

Solar bags will recharge most USB devices

Does a solar powered charger work in Greenland?

Portable solar power banks will slowly charge up in direct sunlight however because of the climate in Greenland and the limitation of the smaller footprint of the solar panel it won't be dependable for travellers. The compact surface area of the cells means a solar charger needs to be left in powerful sunshine for an extended period of time to produce enough energy for a single charge, which might prove difficult to continually pack and unpack a solar power bank then wait for it to recharge between cloud cover.

  • Instead, the much larger durable solar panels used on a solar backpack will give the bag the ability to create more electricity within a faster period of time, and could generate a smaller power when cloudy.
  • A phone which has been plugged directly into a USB charging port of a backpack should trickle charge the battery during sunny spells in Greenland, but this could be inconvenient to have a phone continuously tethered in the bag should it be needed frequently. Unlike a small solar power bank that needs to be unpacked and facing the sunlight, a solar powered bag is constantly exposed to light so can be recharging a regular power bank throughout the day.
  • Because of the weather in Greenland a solar bag should have the bare minimum solar cell efficiency of 22% or greater, be able to generate at least 6 watts of power and can be used with a 10,000mAH power bank or greater.
  • They come in rucksack, laptop messenger and backpack styles which makes them ideal for travel, work and domestic use. The flexible and durable solar panels used in solar powered bags have been made to survive bending and scratching, unlike regular solid solar cells.  [17] [18] [AD]

Greenland chargers

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 Greenland?

If you are travelling to more than one country or bringing more than one device the best international travel charger for Greenland to buy is a multiple USB port charger which includes compatible plugs such as a 4 port USB travel charger. Greenlanders use four different standards of power outlets (types E, C, F and K) and bringing this will ensure that you are covered for type C. Because these types of chargers are supplied with interchangeable pins and can handle 100 to 240 volts it makes them ideal for over 100 countries around the world just by switching the heads over. If your type of device supports Fast Charge (note that not all USB devices can) then you will benefit from much quicker recharging times by using one of these USB travel chargers, along with support for more power demanding devices.

Unlike other chargers having a 4 port charger means you can recharge more than one device at once without needing to bring individual power adapters on your trip. Only packing a single international travel charger will keep the overall weight down, making it perfect 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 travel adapters can be used at home so when you're not travelling they can be used under your bedside table charging multiple smartphones and tablets using only a single power outlet.

We suggest searching for a flexible power adapter like this online; the multipurpose power adapter illustrated below is the 4 Port USB Wall Charger which has been successfully tested with multiple USB devices in numerous different countries around the world with perfect reliably. [7] [AD]

What USB charger do I need for Greenland?

Why use a travel USB charger for Greenland?

  • Normal travel USB chargers include 4 or more USB charger ports, meaning you now only need to bring a single charger to charge multiple devices. It helps reduce the weight of your baggage by only packing a single USB wall charger instead of bringing multiple individual power chargers with you.
  • All travel USB power chargers include swappable plug heads for various regions thereby making them perfect if travelling to multiple countries which are likely to use a different outlet to Greenland.
  • A good charger is lightweight, compact and rugged - perfect for rigors of travel rather than risking bringing along a domestic charger which might be impossible to replace or repair in Greenland.
  • USB chargers can accept both the 220 volt power outlets in Greenland along with other voltage standards across the world.
  • There is a possibility that some hotel bedrooms or accommodation in Greenland only have one wall outlet, by bringing a travel charger with multiple USB ports allows you to share out the single wall outlet with all your devices rather than waiting to charge one device at a time.
  • Because of their versatile nature a travel USB charger takes the worry out of visiting any unknown destination as they are guaranteed to work almost anywhere around the world.
  • Power outlets found in airports can be in short supply and the demand for charging multiple cell phones and tablets during departure can be high, therefore 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 charger allows for unexpected surges to prevent damage to any devices attached to it. Trying to repair an overloaded mobile phone or tablet in Greenland might prove difficult and expensive.
  • Higher priced USB travel chargers should also feature a power outlet strip to allow you to power multiple low wattage devices such as laptops, but please be aware these will be unsuitable for high powered appliances such as hair dryers or clothes irons. See the section on using travel appliances in Greenland for helpful advice and guidelines on the best power adapter for using a high wattage appliances with a Greenlandic power outlet.
  • Certain tablets and mobile phones might require more than the standard 500 milliamps produced from a standard 5 volt USB adapter to charge or provide fast charge. Ensure that the USB power adapter can support fast charging incase any of your devices need additional power.
  • When back at home travel USB chargers can still be useful by recharging multiple mobile phones and tablets every day using only a single power outlet. [7] [AD]

What is the best USB charger for Greenland?

A 4 port USB travel charger is the most compact option for travellers from around the world wanting to recharge devices using USB, however for those also wanting to use their domestic plugs the following power adapters provide larger but more versatile solutions. All three power converters offer surge protection which can be crucial for visitors of counties with unstable power grids. These power converters are supplied with interchangeable type C, I and G plugs covering both Greenland and over 150 countries around the world:

  • BESTEK Portable International Travel Voltage Converter - The BESTEK international travel adaptor has 4 USB charging ports with 3 AC power outlets and is the best selling compact power adapter for travellers originating from North America going to Greenland.
  • ORICO Traveling Outlet Surge Protector Power Strip - Likewise having 4 USB ports but only 2 AC power outlets the travel adapter from Orico is also aimed at travellers originating from the US using type B plugs. This is a much more cost effective alternative to the BESTEK with just one less AC outlet for almost half the price.
  • BESTEK International USB Travel Power Strip - This power strip has just 2 AC outlets but offers 5 USB charging ports. This versatile power strip is compatible with both American plugs and popular plug types A, D,E/F, G, H, I, L and N making it perfect for most travellers from around the world visiting Greenland. [7] [AD]

Power converters for Greenland

What does a power converter for a Greenlandic power outlet do?

A power converter allows travellers to use a 100, 110 or 120 volt electrical device with a 220 volt Greenlandic 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 Greenland?

A cheap, small and lightweight power adapter (or plug adapter) changes the shape of the plug on your appliance to fit into a power outlet in Greenland, but a heavier and more expensive power converter will transform a 220 volt Greenlandic power outlet to work with a non-220 volt appliance. [19] [AD]

Do I need a power converter for Greenland?

If visiting Greenland from a different country please ensure your device can accept a 220 volt power supply.

  • You need a step down power converter if you are visiting Greenland from a country that uses 100-120 volts and your device or appliance won't support 220 volts. See the WikiConnections world power outlets guide to see which voltage your country uses.
  • You shouldn't need a power converter if you already use either a single voltage device that works with 220 volts or one that supports dual voltage.
  • Normally electrical devices designed for a lower voltage such as 110 volts and used with 220 volts run a risk of a blown fuse, damage to your device or even an electrical fire hazard.
  • You don't need a power converter if you need to charge a smaller electrical device such as a cell phone or laptop 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 supplying power to appliances which draw more power or generate heat (such as hair dryers or clothes irons) then you will need to use a more expensive higher wattage heavy duty power converter.
  • Investing a smaller robust dual voltage travel appliance could be more cost effective and practical than trying to carry a much heavier power converter just to use your existing domestic appliance in Greenland.
  • Read these guides on how to use clothes irons, curling wands, hair dryers and flat irons with a Greenlandic power outlet which includes advice for some affordable dual voltage alternatives.  [10] [20] [AD]

What kind of converter do I need for Greenland?

You need to use a step down power converter which will allow you to use any 100, 110 or 120 volt appliance with a 220 volt Greenlandic power outlet. [10] [AD]

What voltage does Greenland use?

Greenland uses 220 volts in their normal power outlets. [2]

https://www.iec.ch/worldplugs/

How to convert 220 volts to 110 volts

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

Voltage converter

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?

Single voltage hair dryer

What voltage is my device?

The easiest way to tell 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 plugs into. The location might vary depending on the make or model of your device and could also be written on the box.

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

Substantiations

See the power adapter substantions section for more information on how we compared travel adapters (October 2018).

What type of adapter do you need for Greenland?

Which type of plug adapter do I need to bring to Greenland?

The plug adapter or power converter which is suitable for Greenland will depend on various requirements. Before choosing which adapter to bring we recommend using the following checklist:

What types of electrical items do you need to charge?

A USB powered phone

What types of electrical items do you need to charge?

  • There are three types of electrical items:
    • Low wattage electrical items which can be plugged into an electrical outlet - for example cameras or laptops.
    • High wattage appliances which plug into an electrical outlet - for example hair straighteners and clothes irons.
    • USB devices which connect to a USB port - for example phones.
  • Should you only have to take just USB powered devices to Greenland then a simple travel USB wall charger is ideal because you will only need to pack one charger whilst leaving your domestic chargers at home.
  • Travel power strips are built for powering and converting voltage for several low wattage devices of any voltage, but unsuitable for high wattage appliances (such as hair straighteners) that need voltage conversion, potentially overloading it.
How many devices are you bringing to Greenland?

How much are you packing

How many devices are you bringing to Greenland?

  • List all the devices and applicances you intended on packing for Greenland (such as cell phones, laptops, eReaders, clothes irons or hair straighteners).
    • Remember to allow for more electrical devices at a later date. Do you intend on buying a new mobile phone computer next year?
    • There are an increasing amount of rechargeable devices such as electric shavers which use USB as a power source. Therefore if you have to replace a device it could need a USB adapter so please ensure your travel adapter has enough spare ports to support these additional devices as well.
  • Will you also be travelling with a partner who will need to charge their devices too?

  • You could find that accommodation might offer only one power outlet on the wall, this could be an inconvenience when charging up batteries of more than one electronic item overnight because you'll only be able to recharge one device at a time.
  • To charge more than one device at the same time we suggest packing a travel power strip or travel USB wall charger that can charge multiple USB ports and power outlets. [8] [AD]

What is your budget?

  • Cheap power adapters start at under £10 which charges one device in one location (provided that works with 220 volts or is dual voltage), but paying roughly £15-£20 will allow you to power multiple devices at once and be able to bring them to multiple different countries.

Are you intending to visit anywhere else abroad in the future?

Is Greenland the only country you'll be visiting?

  • Most simple plug adapters will typically only work in a single country which they are designed for, therefore if you are visiting multiple countries then you'll need to pack additional plug adapters which can in turn add to the weight you 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.
Will it take you a long time to travel to Greenland?

Using a phone at the airport

Will it take you a long time to travel to Greenland?

  • If you're taking a longer journey to get to Greenland think about bringing a convenient 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 right before a long haul flight.
  • As not all airlines and airports actually have power outlets for customers we recommend bringing a travel portable charger for recharging on the go. After arriving you could have to use your cell phone for making telephone calls, messenging, using sat nav or reading itineraries - so it is recommended that your phone will have enough charge remaining. [4] [AD]

Do you still need use your charger when returning to the UK?

Will you always have good access to electrical power?

  • The electricity in Greenland is stable but if you want to visit another country you might need a power adapter which will protect your electrical appliances. The power can sporadically fluctuate in some other countries and this could possibly cause damage to your devices, so use a power adapter which offers built in surge protection such as a travel power strip.
  • Packing a portable charger or a solar backpack will prepare you for any power cuts and countries with limited electricity.  [4] [4] [17] [AD]
