If you’re travelling to Thailand, you don’t want to be without power. So, make sure you have the correct power plug adapter and, depending on your country of origin, a necessary voltage convertor. We provide up-to-date information on all the types of electrical outlets used in Thailand as well as their standard voltage and frequency. 

Power plug types in Thailand

Voltage and frequency of electricity in Thailand

Thailand has a standard electricity voltage of 220 volts and a frequency of 50 hertz. You need to be careful when it comes to different electrical voltages and frequencies. If you’re coming from a country that has a lower standard voltage such at 127 Volts you will likely need a voltage converter. If the frequency of your device is not 50 hertz like in Thailand, it’s recommended not to use it without a voltage converter which also changes the frequency (hertz). Some devices will show a range of volts and hertz which means they can more easily be used in different countries without the risk of damage.

Electricity in Thailand

The main power generation in Thailand is provided by natural gas then followed by coal. Renewable energy production is increasing. A few hydro plants are already in operation accounting for seven percent of Thailand’s power output (as of 2015). Nuclear energy production was on the table until the nuclear disaster in Japan which put Thailand’s nuclear plans on hold.  

Power plug and electricity information has been collected from the International Electrotechnical Commission (IEC) and the relevant electrical standards from individual countries. Anything we missed on power plugs in Thailand? Please leave us a reply.
