In Thailand, the voltage of domestic AC is 220 volt (50 cycles). Foreign visitors are advised to bring along travel adapters to fit the outlets in the country.
Electrical sockets in Thailand are compatible with both flat parallel prongs (like in the United States and Japan) and two round pins (like in most European and Asian countries). While two-pin sockets are common in Thailand, some establishments like hotels and offices also have three-pin outlets installed.
