Power adapter types and world power outlets

The purpose of this page is to explain which power outlets to expect in a foreign country, different types of power adapters, practical advice on the best travel adapters to buy and help on deciding which power adapter you need to bring. For practical advice on bringing electronics to specific countries read our individual guides on power outlets around the world and how to recharge popular cell phones, tablets and electrical appliances when travelling to different countries.

Different types of power outlets

How many different types of power outlets are there?

Lack of global standardisation means there are now 14 different shapes and sizes of plug sockets from Type A to Type N with power supplies ranging between 100 to 240 volts. With 80% of countries adopting more than one type of plug socket this can make preparing for a holiday or business trip much harder. Various regions have attempted to standardise power outlets across multiple countries. For example, Type C is used widely across Europe, however, due to historical reasons each country has its own unique set of power outlets which all use different types of plug sockets, frequencies and voltages. [1]

Power adapters

What type of power adapter do I need?

This will depend on which country that you are visiting from the UK, read our individual guides on each country which includes the type of power adapter you need, if you need to bring a power converter along with guides for using common appliances and electronics for each country.

What is a power adapter?

What is a power adapter?

A power adapter is a lightweight, small and typically cheap plastic adapter which allows an electrical plug from one country to fit into an electrical appliance in another country.

A typical power adapter body is square in shape and measures 2 inches wide, 2 inches tall and 1 inch deep with the pins adding an additional potential 1 inch in depth depending on the type of adapter. Depending on the make and model of the power adapter there are a number of slots, shutters and holes in the front face of the adapter which are designed to accept a single plug.

Power adapters are also known as: travel adapters, power adaptors (alternative spelling), plug adapters, electrical adapters, mains travel adapters or electrical adaptor. [2]


What does a power adapter do?

A power adapter allows a visitor travelling from a different country to use their own electronic and electrical appliances simply by altering the shape of the plug from one type to another.

Do I need a power adapter?

If the type of power outlet in the country you are visiting is different to the shape of the power plug you wish to use then you will need to use a power adapter.

Can a power adapter change the voltage from a power outlet?

No; a power adapter only adapts the shape of a plug to fit into a different type of power outlet and isn't designed to convert different voltages. Use a power converter for changing the voltage of an incompatible appliance from a different country.

Where to buy a power adapter in the UK

Power adapters for sale in an airport

Where to buy a power adapter in the 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.

Which type of power outlets does a Europlug fit into?

A Type C plug adapter Europlug will fit into types C, E, F, H, J, K, L and N power outlets.  [3] [4] [AD]

Travel adapters

Universal Travel Power Adapters

A universal travel adapter

Universal Travel Power Adapters

Benefits of a universal travel power adapter

  • Perfect when visiting to multiple countries. Typical models will work in over 150 different countries.
  • An all-in-one design, small and lightweight.
  • Typically costs £20-£25.
  • There are some universal travel adapters that have multiple charging ports for USB devices built in.
  • Straightforward operation.
  • Some models include a built in surge protector, this will prevent any device from being overloaded by an unstable power grid.
  • The pins retract so don't get caught against other items when packed in luggage.
  • When you return to the UK the travel adapter will still be useful as a USB charger.
  • Typical models change shape to fit Types A/B, E/F, G and I power outlets.

Disadvantages of a universal travel power adapter

  • Universal travel adapters only charge a single plug.
  • Universal travel adapters will overload when used with a high powered appliance; for example clothes irons, hair straighteners, kettles, curling irons or hair dryers.
  • They don't have include a built in voltage converter.
  • As with any adapter with moving parts this could be fragile on some models, we recommend avoiding cheaper models in case they fail whilst abroad.
  • A universal travel power adapter might not be completely universal - adapters might not work in some countries with less popular power outlet types. [6] [AD]
Travel USB Wall Chargers

A USB travel charger with swappable plugs

Travel USB Wall Chargers

Benefits of a travel USB wall charger

  • Works in over 150 countries around the world.
  • Perfect if you only need to charge USB devices such as iPhones, tablets or eReaders.
  • Supplied with interchangeable adapter heads which make them versatile in a large number of locations. The interchangeable adapter heads which are supplied with USB wall chargers are usually small and lightweight making them easy to store in hand luggage.
  • Expect to pay under £15.
  • You will only need to bring one unit instead of bringing multiple domestic USB power chargers. Typically travel USB chargers include 4 or more USB charger ports, meaning you now only need to bring a single charger to charge multiple devices. This helps cut down on the size and weight of your luggage by only needing to pack one USB wall charger rather than needing to bring several USB power chargers.
  • Includes a built in surge protector. The power grid in some countries can be unstable, a quality travel USB wall charger allows for unexpected fluctuations and will prevent damage to any devices connected to it. Trying to repair an overloaded cell phone or tablet abroad might prove to be difficult and expensive.
  • Good power chargers are compact, rugged and lightweight; perfect for rigors of travel instead of than risking bringing along a domestic charger which might be impossible to replace or repair whilst abroad.
  • Power outlets found in airport departure gates can be scarce and demand for charging multiple cell phones from other passengers before a flight can be high, therefore a USB travel charger with multiple ports and the ability to charge quickly is ideal.
  • It's possible that hotels 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 travelers instead of waiting to charge each device one by one.
  • After you return to the UK the USB charger can still be useful for every day use.
  • Certain cellphones and tablets might require more than the usual 500 mA supplied by a standard 5 volt USB power adapter to charge or provide fast charge. Premium USB chargers will support fast charging should any of your devices require additional power.
  • The swappable heads will fit in Types A/B, E/F, G and I power outlets.

Disadvantages of a travel USB wall charger

  • Restricted to USB ports so you can't charge any appliances, only USB powered devices.
  • Multiple heads mean more items to carry separately rather than a single unit. [7] [AD]
Travel Power Strips

Power strips feature multiple USB ports

Travel Power Strips

Benefits of a travel power strip

  • Some models work in over 200 countries around the world.
  • A travel power strip is capable of powering more than one appliance or device at the same time from just a single power outlet.
  • Some travel power strips also feature multiple USB charge ports.
  • Be prepared to pay £40.
  • Some models have voltage conversation for lower wattage devices (for example laptops). So even if your device isn't dual voltage it can still be used with just a travel power strip in areas with different voltages. This can make them a cheaper and more lightweight substitute for a dedicated power converter depending on what you wish to power.
  • Offers surge protection. The voltage from power grids in certain countries could be tempremental, a sudden surge in power can damage or disable your delicate electronic devices. There are some power strips which have a surge protector built in which aims to protect any electronics from being overloaded by unstable power grids.
  • When you return to the UK it should still be useful as a power strip and USB charger.

Disadvantages of a travel power strip

  • The conversion on travel power strips doesn't support high wattage appliances such as hair straighteners and clothes irons.
  • Due to the size and weight of a power strip it might be unsuitable for packing in hand luggage if space is at a premium.
  • Travel power strips could be considered excessive if you only bring a small number of items that need powering. [8] [AD]
  • Power strip models for sale in the UK only include type B, F, G and I plug adapters so you may need to use it along with an additional power adapter to work in some countries.
Power Plug Adapters

A small and lightweight type D plug adapter

Power Plug Adapters

Benefits of a power plug adapter

  • Cheapest option with prices starting under £10.
  • Small, light and compact.
  • Simple to operate.

Disadvantages of a power plug adapter

  • Only one power adapter per appliance - for every individual appliance you will also need to bring a separate plug adapter.
  • If you wish to power a USB device then you also still need to pack your USB charger.
  • Adapter only changes the shape of the plug to fit a power outlet and won't change the voltage, if your device uses a different voltage and isn't dual voltage then you will need to bring a separate voltage converter.
  • Should you plan on visiting more than one country you might need to bring along multiple power adapter types.
  • Your hotel room may only have a single wall outlet, therefore you'll only be capable of powering one appliance at once.
  • No use when you return to the UK. [9] [AD]
Plug Adapter Sets

A power plug adapter set

Plug Adapter Sets

Benefits of a plug adapter set

  • Covers every eventuality and not just individual countries.
  • The most flexible option for frequent holidaymakers and business travellers visiting multiple countries.
  • Because prices are roughly £5-£10 for a set, buying in bulk will work out cheaper than buying multiple plug adapters for multiple trips costing around £5 each.
  • A typical plug adapter set includes Type A, B, C, D, E/F, G, H, I, J, L, M and N adapters.

Disadvantages of a plug adapter set

  • Will involve some planning; before any trip you will need to decide which power adapters to bring. Alternatively bring every plug adapter in the set with you, with only one of the set being useful at any one time.
  • Not every plug adapter type is included (especially the less common adapters) - so check that the set that you intend to buy includes the ones you need.
  • Each adapter only changes the shape of the plug but doesn't convert the actual voltage.
  • Plug adapter sets aren't as popular in UK marketplaces so you may encounter difficulties finding one to purchase.
  • You will still need to bring separate chargers for USB devices. [5] [AD]
Voltage Converters

Larger voltage converters

Voltage Converters

Benefits of a voltage converter

  • A step down voltage converter should allow you to power any 110-120 volt appliance in a 220-240 volt country and vice versa.
  • Voltage converters have a surge protector to prevent your electronics from being overpowered.

Disadvantages of a voltage converter

  • A power converter only changes the voltage and won't change the actual shape of the plug, therefore you may still need to use a suitable power adapter.
  • The size and weight of most models makes them impractical for carrying in hand baggage.
  • A voltage converter won't be useful when you return to the UK.
  • It is typically much cheaper to buy a dual voltage travel appliance capable of using any voltage than to buy a much more expensive power converter to use your existing single voltage domestic appliance.
  • Expensive; almost £140. [10] [AD]

What is the best USB world travel adapter to buy?

Due to fourteen different types of power outlets being used around the world means there is no single travel adapter suitable for every single country. However, a multiple USB port charger such as a 4 port USB travel charger is versatile enough to cover a large number of the world's most popular travel destinations. These chargers are supplied with interchangeable heads which handle 100 volts to 240 volts which give you the freedom to travel to multiple countries and recharge your devices simply by swapping the heads over.

Having 4 USB ports will allow you to recharge multiple devices at the same time without needing to pack 4 individual power adapters. An added benefit of only packing a single lightweight travel charger frees up space, making it ideal to store in hand luggage and available at the airport. If your device can support Fast Charge (not all USB devices do) then you'll benefit from much quicker recharging times and will also support more power hungry devices.

Due to their flexibility these types of power chargers can also be used back at home so when you are not on vacation they can be used for charging multiple smartphones and tablets overnight whilst using only a single power outlet.

If you travel frequently we suggest searching for a multipurpose power charger like this online, the travel charger illustrated below is the 4 Port USB Wall Charger which has been tested successfully with multiple USB devices in numerous foreign countries with good reliably. [7] [AD]

What type of adapter do you need?

Which type of power adapter should you buy?

The plug adapter or power converter to buy will depend on various requirements, prior to choosing which one to bring we suggest reading this checklist:

How many electrical items will you be bringing?

How many devices are you packing

How many electrical items will you be bringing?

  • List how many electrical items you'll need to pack (for example laptops, phones, tablets, clothes irons or hair dryers).
    • Remember to allow for more electrical devices at a later date.
    • There are an increasing number of smaller rechargeable devices (such as electric shavers) which are switching to using USB powered recharging. The next time you buy a new device it could use a USB power adapter so allow for enough spare USB ports to support these additional devices as well.
    • Will you also be travelling with family who will need to use their electronics too?
What different types of electrical devices do you need to use?

A USB powered phone

What different types of electrical devices do you need to use?

  • There are three different types of electrical devices or appliances:
    • Low wattage electrical devices that plug into a power outlet - for example a camera.
    • High wattage electrical appliances that plug into a power outlet - for example hair dryers and curling irons.
    • USB devices which connect to a USB port - for example phones.
  • If you only want to take just USB powered devices then you'll find that a travel USB wall charger is perfect as you'll only have to pack asingle compact charger and leave your domestic chargers at home.
  • Travel power strips are made for powering and voltage conversion for several low wattage devices of any voltage, but unsuitable for high wattage appliances (such as hair dryers) which require voltage conversion.
Will your devices and appliances work with a different voltage?

Dual voltage hair dryer

Will your devices and appliances work with a different voltage?

Do you only need to recharge USB devices?

A USB cable

Do you only need to recharge USB devices?

  • If you only need to recharge USB powered devices such as cell phones abroad then it is recommended to only bring a travel USB wall charger.
  • If you bring a normal power plug adapter you will still need to carry the domestic USB power charger that came with your device too, thereby adding more weight and items to your baggage. [7] [AD]
How many wall outlets will be available?

Are multiple outlets available

How many wall outlets will be available?

  • A hotel may only offer one power outlet on the wall, this may be a problem when simultaneously charging up the batteries of multiple devices such as cellphones, 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.
  • To charge more than one device simultaneously we recommend packing a travel power strip or travel USB wall charger which can power multiple power outlets and USB ports simultaneously. [8] [AD]

Are you planning on visiting anywhere else abroad in the future?

Do you plan on travelling with just hand baggage?

Are you only using hand baggage

Do you plan on travelling with just hand baggage?

Do you plan on visiting multiple countries?

  • A single power adapter only typically works in a single country that it is built for, therefore if you want to visit more than just one country then you'll need to carry additional plug adapters.
  • On the other hand travel USB wall chargers and universal travel adapters are perfect for travelling to multiple countries becuase of their interchangeable head system.

How much can you afford to pay?

  • A basic power adapter starts from around under £10 which powers only one device in only one country (provided that works with different voltages or is dual voltage).
  • Paying roughly £20-£25 for a universal travel power adapter will allow you to charge multiple devices at once and bring them to a wider number of countries. [6] [AD]
How long will your journey take?

Making a call after a long haul flight

How long will your journey take?

  • For long journeys consider a airport-suitable charger that works in different power outlet types, one that is small enough to pack in hand luggage and has Fast Charge so can quickly top up phones and tablets right before a long flight.
  • Not all airports actually have power outlets for travellers, one option is to bring a portable charger for recharging USB devices on the move. After landing in another country cell phones are excessively used for making calls, checking emails, using sat nav to locate accomodation or reading an itinerary; a charger ensures that your phone will have ample power left to do these. [12] [AD]

Would you like to use your charger when returning to the UK?
