Thai power outlet

What adapter do I need for Thailand?

The type of plug adapter, power converter or charger that you'll need when visiting Thailand all depends on the voltage and type of device that you're trying to use in a Thai power outlet. If you're not sure which voltage your device uses then please read the section below on how to find out the voltage of your device before going any further.

  • 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 can run on 220 volts or is dual voltage and the plug will fit in a Thai power outlet then you can use it in Thailand without needing anything else.
  • If your device can run on 220 volts or is dual voltage but your plug doesn't fit in a Thai power outlet then you will need a suitable plug adapter for Thailand such a Type B plug adapter [3]. Please Note that a plug adapter for Thailand (or power adapter) changes the actual shape of the plug on your device to fit into a plug outlet found in Thailand, but won't change the voltage from 220 volts to a different voltage.
  • If your device doesn't run on 220 volts and isn't dual voltage you'll also need a power converter for Thailand to convert the voltage from 220 volts to the correct voltage on your device. You'll still need to bring a suitable plug adapter for Thailand if your power converter doesn't include the correct Type B plug adapter.
  • If you need to recharge your USB devices such as cellphones or tablets then a USB travel power adapter is suitable and it should be dual voltage, however ensure that you bring one which includes a Type B plug adapter otherwise you'll still need to bring a suitable plug adapter for Thailand.

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

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 [6]. 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 iKits 4 Port USB Wall Charger [6] which has been successfully tested for powering multiple USB devices in numerous foreign countries with perfect reliably.

What USB charger do I need for Thailand?

Why use a travel USB charger for Thailand?

  • Normal travel USB chargers include 4 or more USB charger ports, meaning you only need to bring a single charger to charge all your devices. This reduces the size and weight of your baggage by only packing a single USB wall charger instead of bringing numerous individual USB power chargers.
  • All travel USB power chargers should include interchangeable plug heads for different countries making them ideal if visiting different countries across Asia which are likely to use a different standard to Thailand.
  • Good travel power chargers are compact, rugged and lightweight; perfect for rigors of travel rather than risking packing a domestic charger which could be hard to repair in Thailand.
  • USB travel chargers can accept the 220 volt power outlets in Thailand and other voltage standards in other countries.
  • It's possible that some hotel rooms or accommodation in Thailand might only have one power outlet, by using a travel charger with multiple USB ports means you can share the single wall outlet with family or other traveler rather than having to wait to recharge one device at a time.
  • Due to their flexible nature they take the uncertainty out of visiting an unknown destination as they are guaranteed to work practically anywhere on the planet.
  • Power outlets found in airport departure lounges are often scant and the demand for charging multiple cell phones and tablets before a flight can be high, therefore a USB travel charger with multiple ports and the ability to charge quickly is perect.
  • Sometimes the power grid in a country can be unstable, a good travel charger allows for unexpected surges to prevent damage to any devices connected to it. Attempting to repair an overloaded cell phone or tablet in Thailand might prove difficult and costly.
  • More expensive USB chargers should also include a power outlet strip to power multiple low wattage devices such as laptops, howeverthese will be unsuitable for high wattage appliances such as hair dryers or clothes irons. For further information please see the guide on using travel appliances with a Thai power outlet for guidelines on the most suitable power adapter for using a high powered devices in a Thai power outlet.
  • Some cell phones could pull more than the standard 500 milliamps produced from a standard 5 volt USB power adapter to charge or provide fast charge. Premium USB travel chargers will support fast charging incase any of your devices need extra power.
  • On back at home travel USB power chargers can still be used by charging multiple cell phones every night using only a single power outlet.

Power converters for Thailand

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

A power converter enables travellers 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?

An expensive and bulky power converter [8] converts a 220 volt Thai power outlet to work with a non-220 volt device, but a more lightweight and smaller power adapter [7] (or plug adapter) changes the shape of the plug on your appliance to fit into a power outlet found in Thailand.

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 [9] 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 an electrical fire hazard, blowing a fuse or damage to your device.
  • You don'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 [10].
  • 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.

Do I need a power converter for Thailand if I'm visiting from America?

The voltage from a plug outlet in Thailand is different to a US supply, therefore use a step down power converter [9] if your appliance or charger isn't dual voltage.

What converter do I need for Thailand?

To use any 100, 110 or 120 volt appliance in Thailand you will need to buy a step down power converter [9].

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 [9] 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.

What voltage is used in Thailand?

Thailand uses 220 volts in their power outlets.

What voltage is my appliance?

Dual 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 be written 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.
