Thailand power adapters - what plugs are used in Thailand?

Thai power outlet

Summary

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 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 [2]. 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.

Background

If packing for a vacation to Thailand it's helpful to know in advance if you can use all your vital electronics such as cell phones and laptop computers when you arrive at your hotel. By not knowing which power socket is being used in Thailand you could end up either weighing your bags down with unnecessary spare adaptors or bring the wrong power adaptor, leaving you needing to buy or borrow a potentially expensive power adaptor when you get there. Complicated frequencies and standards can all be confusing when planning to travel to another country especially to the first time traveller. However this isn't as complex as it appears, with only a handful of different types of plug sockets used in the world this guide tells you exactly what you'll need in advance to charge your electronics in Thailand. This page contains links to step by step instructions showing you which power adapters you'll need to power your devices when visiting Thailand using their standard types B, A or C 220 volt 50Hz power outlets, Type B power outlets will be typically used by most Thai. Most power adapters are different depending on which area you taking a trip to so we recommend that you read the Wiki Connections travel power adapters list for a complete list of regions. We suggest referring to the Thailand Wikipedia page [1] for more information prior to the area.

Is the voltage in Thailand the same as the US?

The voltage in Thailand is 220 volts, whereas 120 volts is used in the US. If your American charger or appliance doesn't support dual voltage then you need a power converter for a Thai power outlet which allows a 120 volt US device to work in a 220 volt outlet.

Is a plug socket in Thailand the same as in the US?

An American plug will fit into outlets used in Thailand, both the voltage and frequency are different so if your appliance or charger isn't dual voltage use a power converter for Thailand and ensure that it works with 50hz.

Thailand USB 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 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 [5]. 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 [5] 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 is the difference between a power converter and a plug adapter?

Voltage converter

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

An expensive and bulky power converter [7] converts a 220 volt Thai power outlet to work with a non-220 volt device, but a more lightweight and smaller power adapter [6] (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?

If travelling to Thailand from a different region make sure that the device can accept a 220v supply.

  • If charging a USB device which was purchased in a country which uses a lower voltage such as 120 volts ensure your device is dual voltage (marked with a 100-240 volt notation) otherwise you may need to use an additional International travel voltage converter [9] to stop the device from overheating whilst powering it.
  • When supplying power to larger appliances if you are traveling to Thailand from a lower 110 volt country you will need to use a much larger Step Down Voltage Converter [8] to convert the voltage from 110 volts to 220 volts.

See the list of world power outlets page to find out which voltage your country uses.

What voltage is my appliance?

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 diffence) 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.
