Can I Use My Electric Toothbrush in Thailand?

Q: What plug type does Thailand use?

Thailand uses Type A/B/C/O sockets at 230V / 50Hz.

Based on what's typical for this device — confirm on the label to be sure.

Typical profile: Your electric toothbrush needs a voltage converter in Thailand.

Why

This country's voltage differs from the device profile, although the plug shape matches. Do not plug in directly. A voltage converter may be an option only after checking the actual INPUT label, load type, startup demand, frequency and both manufacturers' instructions. Wattage alone cannot establish compatibility; using the wrong setup can damage the device or create a fire or shock hazard. Toothbrush charging bases vary: Oral-B lists 100–240V, 220–240V and 110V/60Hz systems. Check the exact base label and manufacturer travel instructions. A plug adapter changes fit only; use a compatible manufacturer-approved base when the local supply is outside the rating.

Thailand runs 230⁠V / 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.

Scope

Thailand AM 2026: Type B in hybrid sockets: Plug Types > Type B: two parallel flat pins plus a round grounding pin, supported by hybrid sockets though becoming less common. Narrow Type B support only; verify the actual outlet and earth connection locally. The same page’s 220 V and Type F wording remains candidate evidence and does not change country values or socket arrays.
Tourism Authority of Thailand: Electricity for visitors: Article body, first two electricity paragraphs (10 December 2019): 50 Hz and US/Japan parallel flat pins / two round pins, mapped to A/C. Older 220 V wording does not verify the current 230 V dataset. Unspecified three-pin sockets do not prove Type B.
Thai Industrial Standard TIS 166-2549: Defines the Thai TIS 166 household plug/socket geometry, mapped here to Type O. It does not prove every legacy or hybrid socket profile travelers may encounter.
Thailand Energy Regulatory Commission: Household tariff voltage: Household tariff Type 1, notes 1-2, specifies 230 V single-phase two-wire meter/service. This regulator claim is distinct from older tourist 220 V wording; it does not establish every building socket or all local variations.
VDE: Power supply and security when traveling: Differences resolved by checked primary evidence: voltage VDE=220 dataset=230-230; sockets VDE=A/B/C/F dataset=A/B/C/O.

Tourism Authority of Thailand: Older visitor voltage wording · Scope: Thailand · checked: 2026-09-30
The 2019 visitor article states 220 V, differing from regulator household service at 230 V. Retained as candidate voltage wording; country data are unchanged.
Thailand AM 2026: Electrical information for visitors · Scope: Thailand · checked: 2026-07-17
Official visitor guidance says 220 V/50 Hz and lists A, B, C, F, and O; this conflicts with the current 230 V and A/B/C/O dataset profile and therefore does not count as verified coverage.

Look for "INPUT 100-240V" on the label. If it shows one voltage only, size any converter from the wattage before buying.

Will a travel adapter let me use my electric toothbrush in Thailand?

Typical profile: No. A travel adapter only changes the plug shape — it does not change voltage. Your electric toothbrush would still receive 230V.

Do I need a voltage converter for a electric toothbrush in Thailand?

Typical profile: 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.
