🇹🇭 What plug does Thailand use?
Type A/B/C/F/O sockets at 220V, 50Hz. Thailand uses a wide mix of plug types (A, B, C, F, and O) at 220V/50Hz — more variety than almost anywhere else, so a multi-standard adapter is the safest choice.| Travelling from | Adapter needed? | Voltage |
|---|---|---|
| The US | No | voltage differs — check your device for 100–240V dual-voltage support before assuming you can skip a converter |
| The UK | Yes | voltage is compatible — most modern electronics handle it fine |
| Canada | No | voltage differs — check your device for 100–240V dual-voltage support before assuming you can skip a converter |
| Australia | Yes | voltage is compatible — most modern electronics handle it fine |
| Continental Europe | No | voltage is compatible — most modern electronics handle it fine |
Thailand actively uses more plug types than almost anywhere else on this list — A, B, C, F, and the rounder Type O all appear in real use, a legacy of decades of mixed imported wiring. Most hotels built for international travelers now install universal sockets that accept several shapes at once, but a multi-type adapter is the safer choice for guesthouses and local stays.

What if I forget my adapter?
Adapters are widely sold at Thailand airports, electronics shops, and convenience stores near hotels and tourist areas — usually at a small markup over what you'd pay at home. If you're stuck, ask at your hotel front desk; many keep a few spares to lend.
