UK to Thailand power adapters - do you need a power adapter for Thailand?

Thai power outlet

What adapter do I need for Thailand?

You will need to pack a Type B plug adapter for Thailand if the plug you intend on using doesn't fit in a Thai power outlet.

The type of power adapter, power converter or charger that you'll need when visiting Thailand all depends on the voltage and type of device that you're attempting to use with a Thai power outlet. If you're unclear about which voltage your device can use then please read the section on how to tell the voltage of your device before going any further.

  • Expect regular power outages in Thailand, we recommend bringing a portable charger if you want to recharge your mobile phone and other devices whilst travelling during a blackout.
  • If you are planning on travelling to Thailand from America then devices and appliances with US plugs will fit into a Thai power outlet without needing a plug adapter. However the voltage is 220 volts so please bring a power converter if your charger or appliance isn't dual voltage, also check that it will work with a 50hz power outlet.
  • If your device is 220 volts or is dual voltage and the plug fits in a Thai power outlet then it will work in Thailand.
  • If your device can run on 220 volts or is dual voltage but your plug won't fit in a Thai power outlet then you'll need a suitable plug adapter for Thailand such a Type B plug adapter. Please be aware that a plug adapter for Thailand (or power adapter) will change the actual shape of the plug on your device to fit into a plug outlet found in Thailand, but but is unable to change the voltage from 220 volts to a different voltage.
  • If your device doesn't run on 220 volts and isn't dual voltage then you'll also need a power converter for Thailand to convert the voltage from 220 volts to the correct voltage for your device. You'll still need to bring along a suitable plug adapter for Thailand if the power converter doesn't use the correct Type B plug adapter.
  • If you simply want to power your USB devices such as cell phones or tablets then a USB travel power adapter is recommended and it will work with any voltage, however make sure that you choose one which has a Type B plug adapter otherwise you'll still need to pack a suitable plug adapter for Thailand[3] [AD]

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

Power adapters for sale in an airport

Where to buy a power adapter for Thailand in the UK

Thailand 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.

Travel Power Strips

Benefits of a travel power strip

  • A travel power strip is able to charge more than one electrical appliance at the same time from just one Thai power outlet.
  • You will find certain models will convert voltage for lower wattage electronics (for example laptops). Even if the appliance isn't dual voltage it can still function with a Thai power outlet by using a travel power strip. This will make them a lightweight and cheaper alternative option to a dedicated voltage converter.
  • Some models also feature a number of USB ports.
  • Voltage from power outlets in some countries could be unstable, a sudden surge in power can damage your delicate electrical items. Some power strips will have a surge protector built in which will protect any device from being overloaded.
  • A power strip can potentially be useful back at home as a USB charger and power strip.

Disadvantages of a travel power strip

  • Unlike a normal voltage converter, the converter on a travel power strip doesn't convert higher wattage appliances such as hair dryers or curling irons.
  • Due to their weight power strips might be too bulky for packing in hand luggage.
  • A travel power strip could be excessive for travellers only bringing a small number of items that need charging. [6] [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 plug adapter to work in some countries.

  • Most universal travel adapters are designed to operate in over 150 different countries.
  • An all-in-one design which is both lightweight and small.
  • Some universal travel adapters also include USB charging ports built in.
  • Straightforward operation.
  • There are some universal travel power adapters which have a surge protector built in, this will protect your device from being overpowered by an unstable power grid in some countries.
  • The retracting pins won't catch against other items when packed in luggage.
  • When you return home it could still work as a USB charger.
  • Changes shape to Types A/B, E/F, G and I plugs so should fit into a Thai power outlet.

Disadvantages of a universal travel power adapter

  • Universal travel power adapters must not be used with a high powered appliance such as clothes irons, microwaves, vacuum cleaners, kettles or hair dryers.
  • The internal moving parts such as pins and shutters might be fragile on some universal travel power adapters making them likely to possibily fail when travelling.
  • Only provide power to a single appliance.
  • A universal travel power adapter might not be fully universal; models might not work in certain countries with less popular outlet types.
  • Missing an in-built power converter means it won't be suitable for electrical appliances which don't support 220 volts in Thailand. [8] [AD]

Power Plug Adapters

Benefits of a power plug adapter

  • Compact and light.
  • Cheap.
  • Straightforward design makes this power adapter easy to operate.
  • Using a Type B plug adapter will be ideal for Thailand.

Disadvantages of a power plug adapter

  • A single adapter per device - for every individual appliance you want to bring you will also need to use a separate power plug adapter.
  • Only modifies the actual shape of the plug to fit in a Type B Thai power outlet but not the voltage used in Thailand, so if your device doesn't support 220 volts and isn't dual voltage then you'll still need to pack a separate voltage converter.
  • Your accomodation may only have a single power outlet, so you will only be able to power a single appliance at once.
  • If you need to charge any USB device then you also still need to bring your domestic USB charger as well.
  • If you plan on travelling to more than just Thailand you might need to pack more than one type of plug adapter for other countries. [3] [AD]
Plug Adapter Sets

Benefits of a plug adapter set

  • A set will typically work out more reasonable than buying multiple individual power plug adapters for multiple locations.
  • Covers every eventuality.
  • The most flexible option for anyone travelling to multiple locations.
  • Includes Type A, B, C, D, E/F, G, H, I, J, L, M and N plugs so should work in Thailand.

Disadvantages of a plug adapter set

  • Will involve some planning; prior to any trip you'll have to decide which adapters to bring in advance, or alternatively pack every power adapter in the set.
  • Means lots of individual plug adapters to pack.
  • The remaining plug adapters will be useless.
  • Not every power adapter types are typically included (and especially the less common adapters) - so check that your set includes an adapter which works in Thailand.
  • Each plug adapter only alters the shape of the plug to fit in a Thai power outlet but not the actual voltage. [9] [AD]
Voltage Converters

A voltage converter

Voltage Converters

UK citizens shouldn't need to use a voltage converter as the voltage in Thailand is 220 volts.

Benefits of a voltage converter

Disadvantages of a voltage converter

  • A voltage converter only changes the 220 volts from a Thai power outlet and won't change the shape of the plug to fit into a Thai power outlet, therefore you'll still need to bring the correct type of power adapter.
  • The normal size and weight of most models of voltage converters makes them impractical for packing in hand luggage.
  • Redundant when you return to the UK.
  • Often better value and more practical to buy a dual voltage travel appliance than to purchase a more expensive power converter simply to bring your existing single voltage domestic appliance in an incompatible location.

Thailand power outlets and plug sockets

What plug sockets are used in Thailand?

Type A, B and C power outlets

What plug sockets are used in Thailand?

There are three different types of power supply used in Thailand, types B, A and C with the primary power outlets being type B:

  • Plug Type A - You can identify the plug socket by two thin adjacent slots next to each other where the pins go.
  • Plug Type B - This plug socket, also called a type B power outlet, can be identified by the 2 slots with a single hole below for the longer ground pin.
  • Plug Type C - You can identify this power socket by 2 circular holes adjacent to each other where the two plug socket pins go. [3] [AD]

What frequency is used in Thailand?

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

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

How do I use a 110 volt appliance in Thailand?

Use a step down power converter should you need to use a 110 volt or 120 volt appliance in a Thai power outlet.

Are there power outages in Thailand?

There are monthly power failures in parts of Thailand.

Are power outlets available in Thailand?

Access to electrical power in Thailand is excellent which spans the entire population.

Should I use a power bank in Thailand?

Due to the lack of a stable power grid in Thailand visitors are advised to pack backup charging solutions if they wish to continue using devices such as mobile phones dependably.

  • During a trip to Thailand increased use of mobile phones for storing itineraries, taking photographs, GPS, social networks and staying entertained will drain power before the end of the day. Beyond the simple missed photograph opportunities a flat mobile phone battery could potentially leave you stranded without sufficient power to make emergency calls or being able to use a satellite navigation app to return back to your hotel or accommodation.
  • Using a portable charger alleviates those concerns as it means you can recharge your mobile phone without needing a wall charger, especially when visiting a country with frequent power outages.
  • A 10,000mAh power bank will supply enough energy to cover over three full charging cycles while a 20,000mAh portable charger should keep an average mobile phone powered for roughly seven days. A mAh value (milli ampere-hours) describes the capacity of the battery and gives an indication of the number of recharges the power bank can achieve, so a higher value will be better for travellers.
  • As long as your laptop supports USB-C charging then a portable charger for a laptop marked with PD (power delivery) that supplies 20Wh or more can be used to recharge that laptop when travelling to Thailand. Be aware that some airlines won't let you bring power banks on an aircraft that supply 100 Wh of power or more and must not be kept in the hold so please check ahead with the airline first.
  • Consumer power banks aren't designed for high powered items that generate heat, but a rechargeable hair dryer or rechargeable cordless flat iron are designed for travelling to areas with frequent power cuts like Thailand.    [4] [4] [12] [13] [14] [15] [AD]

How well do solar battery chargers work in Thailand?

Solar backpacks are ideal for hot climates

How well do solar battery chargers work in Thailand?

The weather in Thailand will be adequate enough to charge solar power bank dependably, however it needs to be left in strong daylight in order to produce enough power for a single charge cycle. It might prove inconvenient to continually unpack a solar power bank then wait whilst it recharges in a sunny area.

  • The larger durable solar panels found on a solar backpack will give the backpack the ability to generate more power within a faster period of time, making them ideal for the climate in Thailand.
  • Phones which are directly plugged into the USB port of a backpack will gradually recharge the battery during sunny periods in Thailand, however might be inconvenient to have a phone continuously connected in the bag during the day if it is to be used frequently. A solar powered bag is usually exposed to sunlight therefore can be charging a regular power bank throughout the day, unlike a handheld solar power bank which needs unpacking and facing the sunlight.
  • Although the climate in Thailand is suitable, a bag should ideally have a solar cell efficiency of 22% or greater, can generate at least 6 watts of energy and includes a 10,000mAH power bank or greater. Unlike regular solid solar panels, the durable and flexible panels used in solar powered bags have been built to survive scratches and bending. Solar bags are found in messenger, backpack and rucksack styles making them perfect for travel, work and domestic use.  [16] [17] [AD]

Thailand 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 Thailand?

When you are travelling to more than one country and bringing along more than just one device the best international travel charger for Thailand is a multiple USB port adapter which includes compatible plugs like a 4 port USB travel charger. There are three standards of power outlets that Thai use (types B, A and C) and bringing this will ensure that you are covered for both types A and C. Because these types of chargers come with interchangeable plugs and handle 100 volts to 240 volts it makes them ideal for over 100 countries in North America, Europe, Asia and Africa simply by switching the supplied heads. If your type of device can support Fast Charge (not all USB devices do) then you will benefit from quicker recharging times by using one of these types of power adapters, plus compatibility with more power hungry devices. Having a 4 port adapter will also allow you to power multiple devices simultaneously without needing to bring individual power chargers. Only bringing a single USB travel charger will also keep the weight down, making it perfect to fold up in hand baggage while travelling. Because of their space saving flexibility these types of adapters can be used at home so when you’re not on holiday they can sit overnight charging multiple tablets and phones without using up an additional power outlet.

For those travelling on a regular basis we suggest buying an adaptable power adapter of this nature at an electronics retailer, the power adapter illustrated below is the 4 Port USB Wall Charger which has been successfully tested for powering multiple USB devices in numerous foreign countries with perfect reliably. [7] [AD]

What USB charger do I need for Thailand?

Why use a travel USB charger for Thailand?

  • Most travel USB chargers include multiple USB charger ports, this means that you now only need to bring one charger to charge multiple devices. Instead of bringing 4 separate power chargers you only need to pack a single 4 port USB wall charger to power up to 4 individual devices, thereby reducing the weight and size of your baggage.
  • Most travel USB chargers will include swappable plug heads for different countries. This is suitable when travelling across different countries which will probably use different standards to Thailand.
  • A good USB power charger is lightweight, compact and rugged - ideal for the rigors of travel instead of than risking bringing a domestic charger which could be impossible to replace or repair in Thailand.
  • USB chargers will accept both the 220 volts used in Thailand power outlets and different voltage standards in other countries.
  • There is a possibility that hotels in Thailand might only have a single wall outlet, by bringing a travel charger with multiple USB ports allows you to share out the single power supply with all your devices instead of having to wait to recharge each device one by one.
  • Because of their versatile nature a travel USB charger takes the worry out of travelling to any unknown country as they are guaranteed to work practically anywhere in the world.
  • Power outlets in airports can be scarce and demand for charging multiple cell phones and tablets from other passengers during departure can be high, so a USB charger with multiple ports and the capability to fast charge is ideal.
  • Some countries power grids are unstable, a good quality travel USB charger allows for unexpected fluctuations and will prevent damage to any devices attached to it. Trying to repair an overloaded smartphone or tablet in Thailand could prove to be problematic and expensive.
  • Premium USB travel chargers should also feature a power outlet strip to allow you to use low powered domestic appliances such as laptops, but please be aware these will be unsuitable for high powered domestic such as hair dryers or clothes irons. Read our section on using travel appliances with a Thai power outlet for helpful advice on the best power adapter to use with a Thai power outlet for high powered devices.
  • Certain tablets and cellphones might require more than the normal 500 mA supplied by a normal 5 volt USB power adapter to charge or provide fast charge. Ensure that the USB power adapter can support fast charging should some of your devices require extra power.
  • Travel USB power chargers can still be useful back at home by recharging multiple mobile phones and tablets every day using a single power outlet. [7] [AD]

What is the best USB charger for Thailand?

A 4 port USB travel charger is the most compact option for travellers from any country wanting to recharge devices via USB, however for those also wanting to use their domestic plugs these power converters provide larger but more versatile solutions. All 3 power converters offer surge protection which is useful when visiting counties with unstable power grids to prevent damage to any connected appliances from voltage spikes. These travel converters come supplied with interchangeable type C, I and G plugs covering Europe, North America, Australia, United Kingdom, Japan, China and over 150 destinations:

  • BESTEK Portable International Travel Voltage Converter - The BESTEK travel adaptor has 4 USB charging ports with 3 AC power outlets and is the most popular compact power converter for travellers originating from North America going to Thailand using type B American plug sockets.
  • ORICO Traveling Outlet Surge Protector Power Strip - Similarly having 4 USB ports but only 2 AC power outlets the travel adapter from Orico is also aimed at travellers originating from North America using type B plugs and gives almost the same set of features as the BESTEK with just 1 less AC outlet for almost half price.
  • BESTEK International USB Travel Power Strip - This power strip has 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 ideal for a wide range of travellers from around the world visiting Thailand. [7] [AD]

Power converters for Thailand

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

Power converters enable you to use a 100-120 volt electric appliance with a 220 volt Thai power outlet.

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

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

A lightweight, cheap and small power adapter (or plug adapter) changes the shape of the plug on your appliance to fit into a power outlet in Thailand, whereas a more expensive and heavier power converter transforms a 220 volt Thai power outlet to work with a non-220 volt appliance. [10] [AD]

Do I need a power converter for Thailand?

When visiting Thailand from another country check your device can be charged using a 220 volt power supply.

  • A step down power converter is needed if you are travelling from a country that uses 100-120 volts and your appliance is incompatible with 220 volts. See our WikiConnections world power outlets guide to find out the voltage your country uses.
  • You won'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.
  • Typically, devices designed to work with a lower voltage (such as 110 volts) and used with 220 volts run the risk of blowing a fuse, damage to your device or even an electrical fire hazard.
  • You shouldn't need a power converter if you wish to power a smaller electrical device such as a tablet or cell phone as these are typically designed for international use and dual voltage, but you should always always check the device for dual voltage support first.
  • If supplying power to high wattage appliances or generate heat (such as clothes irons and hair straighteners) then you will need to use a much larger higher wattage heavy duty power converter.
  • Investing a smaller robust dual voltage travel appliance could be more practical and cost effective than investing in a heavier high wattage power converter in order to use your existing domestic appliance.
  • Read these comprehensive guides on travelling with curling irons, clothes irons, flat irons and hairdryers with Thai power outlets , along with guides for some affordable dual voltage alternatives.  [10] [18] [AD]

What converter do I need for Thailand?

In order to use any 100, 110 or 120 volt appliance in Thailand you will need to buy a step down power converter[10] [AD]

What is the difference between a power converter and a power transformer?

Voltage converter

What is the difference between a power 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.

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 Thai 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 Thailand before plugging that into a Thai 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 Thai power outlet. [10] [AD]

What voltage is used in Thailand?

Thailand uses 220 volts in their power outlets. [2]

What voltage is my appliance?

Single voltage hair dryer

What voltage is my appliance?

One way to tell if a appliance is single or dual voltage is to check for a sticker on the charger, or on the unit itself, typically on the rear of the appliance or near to where the power cord plugs into. The location might depend on the make or model of your unit and should also state on the box.

  • Single voltage devices might have 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 typically 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.

What type of adapter do you need for Thailand?

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

The type of power converter that is suitable for Thailand depends on various requirements. Before choosing the right one to use we suggest reading through the following checklist:

How many electrical items are you packing for Thailand?

How many devices are you packing

How many electrical items are you packing for Thailand?

  • Count how many electrical items you intended on bringing with you to Thailand (for example mobile phones, tablets, laptops, eReaders, curling irons and hair dryers).
    • Remember to allow for more devices at a later date. Are you thinking about buying a new tablet computer next year for example?
    • There are an increasing amount of smaller rechargeable devices such as electric shavers that use USB charging as a power charging source. The next time you buy a new device it could use a USB adapter so please ensure your travel adapter has enough spare ports for these also.
  • Will you also be travelling with family who might need to recharge their devices?
Will you only be planning on charging USB devices in Thailand?

Are you only bringing USB devices

Will you only be planning on charging USB devices in Thailand?

What different types of electrical devices do you want to charge?

A USB powered phone

What different types of electrical devices do you want to charge?

  • There are three types of electrical devices or appliances:
    • Low wattage electrical devices which plug into an electrical outlet - for example cameras or laptops.
    • High wattage appliances which can be plugged into a power outlet - for example hair dryers and curling irons.
    • USB powered electrical devices that charge using a USB port - for example mobile phones.
  • If you only want to bring along just USB powered devices you'll find that a simple travel USB charger is ideal because you will only have to bring that single lightweight charger with your existing USB charging cables.
  • Travel power strips are most suited for powering and voltage conversion for several low wattage devices (such as laptops), however won't work with high wattage appliances (such as hair straighteners) that require voltage conversion and could potentially overload the power strip.

Do your devices and appliances work with 220 volt power outlets?

Do you plan on visiting countries other than Thailand?

How many Thai power outlets will be available?

Are multiple wall outlets available

How many Thai power outlets will be available?

  • Your accommodation in Thailand might only have a single power outlet, this could be an issue when recharging batteries of multiple electronic devices such as cell phones, tablet computers and laptops overnight as you will only be able to recharge one device at a time every few hours.
  • Should you want to charge more than one device at the same time then we suggest bringing a travel power strip or travel USB wall charger which are capable of powering multiple USB ports or power outlets. [6] [AD]

Do you intend to visit anywhere abroad in the future?

How much can you afford to pay?

  • A basic power adapter can power a single device in only one location (providing that it is dual voltage or is compatible with 220 volts) but paying a small amount more will allow you to charge more than one device at once and you will be able to use them in multiple different countries.

Will it take you a long time to get to Thailand?

  • If you are embarking on an extended journey to get to Thailand consider an airport-suitable power charger that can be used with multiple outlet types, one that is light enough to pack in carry-on luggage and can quickly power tablets and phones.
  • Not all airports and airlines actually have power outlets for customers therefore consider packing a battery portable charger for recharging on the go. After arriving in Thailand you might need to rely on a cellphone for making a call, sending texts, using mapping to find your hotel or reading an itinerary; please make sure that your phone will have enough charge stored. [4] [AD]
