what plug sockets are used in thailand

There are four types of plug sockets used in Thailand: types A, B, C, and O. Type A has two flat parallel pins, type B has two flat parallel pins and a grounding pin, type C has two round pins, and type O is unique to Thailand and has three pins. Virtually all sockets in Thailand are hybrid ones, compatible with all four plug types. The standard voltage in Thailand is 220V and the frequency is 50Hz. It is important to note that if you are traveling from the United States of America, you will need a power plug adapter for sockets type C, F, and O, and we recommend packing a 3 to 2 prong adapter in case type B sockets are not available.
