Do you also need a voltage converter in Thailand?
Only for single-voltage heating tools. For those, a dual-voltage travel version beats a bulky converter.
What to avoid
- Cheap adapters with no grounding option if your device has a 3-prong plug.
- Bulky all-in-one converters you don't need — most modern gear is dual-voltage.
FAQ
What adapter do I need for Thailand?
Thailand uses Type A/B/C/O sockets, so you need a Type A/B/C/O plug adapter (or a universal adapter that includes it).
Do I also need a voltage converter in Thailand?
Only for single-voltage (120V-only) devices like hair dryers. Dual-voltage gear (100–240V) needs only the adapter.
Is Thailand 230V or 110V?
Thailand runs 230V at 50Hz.
