Type F (Schuko) plugs: European Type F plugs physically fit Thailand’s hybrid sockets, but the earth clips are not connected, so the appliance is not earthed. Thailand declared appliances sold with Type E/F plugs illegal in 2008 (World Standards). Use a proper adapter for earthed appliances.

Sources (checked 18 Oct 2026): Electrical Safety First: Thailand (230 V, 50 Hz; types A, B, C, O) · World Standards: Thailand (230 V, 50 Hz; types A, B, C, O; Type F note). The IEC’s retired World Plugs list (archived Nov 2020) gave 220 V and types A, B, C, F; we use the two current sources.

Thailand uses Type A, Type B, Type C, Type O. Type A (Two flat parallel pins — used in USA, Canada, Mexico, Japan). Type B (Two flat + round earth pin — used in USA, Canada, Mexico). Type C (Two round pins (Europlug) — used in Europe, Asia, S. America). Type O (Three round pins (TIS 166-2549) — used in Thailand).
Thailand uses 230 volts at 50 Hz. This puts it in the 220–240V range. Most modern electronics (phones, laptops, cameras) accept 100–240V and will work fine with just a plug adapter.
If your home country uses different plug types to Type A, Type B, Type C, Type O, yes — you will need a plug adapter. Whether you need a voltage converter depends on your device. Check the label: if it says '100–240V', you only need a plug adapter.
New Zealanders travelling to Thailand need a plug adapter (Type I to Type A, Type B, Type C, Type O) but no voltage converter — Thailand runs on 230V, the same as NZ's 230V standard.
