Thailand uses Types A, B, C and O plugs, 230V at 50Hz. Travelling from the UK you need a plug adapter. Phone and laptop chargers are usually rated 100-240V, so they only need the right plug.
| Plug type | Types A, B, C and O |
| Type A | two flat parallel pins |
| Type B | two flat pins plus a round earth pin |
| Type C | two round pins (Europlug) |
| Type O | three round pins (Thai type) |
| Voltage | 230V |
| Frequency | 50Hz |
