Travel adapter from Tonga to Thailand
Adapter Required
Yes — coming from Tonga, you will need a travel adapter for Thailand. Tonga uses Type I plugs, and Thailand uses Type A/Type B/Type C/Type O, so the pin shapes will not fit any wall socket.

More about plugs in Thailand
In Thailand, the standard power plug is Type A and Type B and Type C and Type O. The country runs on 230 volts at 50 Hz. That means wall sockets in Thailand can be one of 4 different shapes — Type A, Type B, Type C, Type O, and your plug needs to physically match the socket to fit.
