Power Outlets & Plugs in Thailand

Thailand runs 230V — nearly double the US 120V. Dual-voltage gear needs only an adapter; single-voltage US devices need a converter.

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.
