FAQ

Do United States plugs work in Thailand?

Often yes — the plug shapes are compatible. But check the voltage before plugging single-voltage devices in.

Not safely if it's single-voltage. Thailand runs 230V vs United States's 120V — use a dual-voltage dryer or a converter.

Is the voltage different between United States and Thailand?

United States is 120V and Thailand is 230V. That difference matters for single-voltage devices.
