USA to Thailand

Are you from the USA and planning to travel to Thailand?

Do you need to get a plug adapter?

Maybe. Some socket types are similar but you’ll want to get a power plug adapter just in case the socket you need is not available.

Summary:

  • Electronic appliances with plug A will not fit socket C, F and O. 
  • Electronic appliances with plug B will not fit socket C, F and O. 
  • The voltage and frequency is different in each country so you may also require a voltage convertor for some devices.

Difference in voltage and frequency

You can’t use some electric appliances in Thailand without a voltage convertor, because the standard voltage in United State of America (120 V) is lower than in Thailand (220 V).

Utilizing an appliance not suited for your voltage/frequency can lead to catastrophic damages. To guarantee the safety of your device, make sure you read the label on it before use. Some appliances don’t need a converter at all; if their labels state ‘Input: 100-240V, 50/60 Hz’, then they are certified for international usage!
