Frequently asked questions

What plug type is used in Thailand?

Thailand uses plug types A, B, C, F and O. The most common is type O – the Thai plug. Most sockets are combined and accept type A, B, C and O plugs; older buildings may have only two-pin sockets.

What is the voltage in Thailand?

The mains voltage in Thailand is 230 V and the frequency is 50 Hz. Devices from countries with 220–240 V work without a converter. Devices from countries with 100–127 V (USA, Canada, Japan) should only be plugged in if the power supply says 100–240 V.

Do I need a travel adapter for Thailand?

You need an adapter if your devices have plugs other than types A, B, C, F and O. You won’t need one if you’re coming from Canada, France, Germany, Japan, Poland and United States. Only some plugs fit for travellers from China and India. Travellers from Australia and United Kingdom need an adapter to type O.

Do I need a voltage converter in Thailand?

Not if you’re coming from Australia, China, France, Germany, India, Poland and United Kingdom – the voltage is similar. If you bring devices from Canada, Japan and United States, check their rating labels. Phone and laptop chargers usually work on 100–240 V, but hair dryers, straighteners and kettles often do not – those need a voltage converter.
