Thailand runs 230V at 50Hz but its sockets often accept US-style Type A/B plugs — a dangerous false familiarity. The plug may fit, but a US single-voltage device will still overheat on 230V.

Thailand outlet FAQ
Can I charge my phone in Thailand without a converter?
Yes. Phone and laptop chargers are dual-voltage (100–240V) — you only need a plug adapter.
Is 230V dangerous for US devices?
Only for single-voltage (120V-only) devices like hair dryers — those need a voltage converter. Dual-voltage gear is fine on an adapter.
What plug type does Thailand use?
Thailand uses Type A, B, C, O sockets at 230V / 50Hz.
