Can I Use My CPAP Machine in Thailand?
You're good — plug right in.
Your device's voltage range matches this country, and the plug fits. You can use it directly — no adapter or converter needed. As a final check, confirm the voltage range printed on the device label.
The short answer
Most modern CPAP machines are dual-voltage (100–240V) and need only a plug adapter — but as a medical device, never assume: confirm the exact label and check whether your heated humidifier is frequency-sensitive. Bring the manufacturer's travel power supply, consider a battery pack for flights, and avoid cheap voltage converters that output a non-pure sine wave.
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 CPAP machine in Thailand?
Thailand sockets use Type A/B/C/O. Your plug already fits, so no adapter is needed.
Do I need a voltage converter for a CPAP machine in Thailand?
No. If your CPAP machine is dual-voltage (100–240V), you don't need a converter in Thailand.
What plug type does Thailand use?
Thailand uses Type A, B, C, O sockets at 230V / 50Hz.
