Can I Use My Curling Iron in Thailand?
You'll need a converter.
This country's voltage is different from what your device is built for, but the plug shape matches. Do not plug in directly. You need a voltage converter (transformer) rated above your device's wattage. Using the device without one can damage it or create a fire or shock hazard.
Based on a typical single-voltage US model — confirm your device's label to be sure.
The short answer
Curling irons and straighteners are heating elements: on the wrong voltage they overheat instantly. A US 120V single-voltage iron on 230V can scorch hair, melt, or fail. Lower wattage than a hair dryer, but the same rule applies — confirm "100–240V" on the barrel, or carry a dual-voltage model. Frequency (50/60Hz) does not affect heating.
Thailand runs 230V at 50Hz. 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.

FAQ
Will a travel adapter let me use my curling iron in Thailand?
No. A travel adapter only changes the plug shape — it does not change voltage. Your curling iron would still receive 230V.
Do I need a voltage converter for a curling iron in Thailand?
Yes — your device runs on a single voltage that doesn't match Thailand's 230V.
What plug type does Thailand use?
Thailand uses Type A, B, C, O sockets at 230V / 50Hz.
