Can I Use My Hair Straightener (Flat Iron) in Vietnam?

Q: What plug type does Vietnam use?

Vietnam uses Type A/C sockets at 220V / 50Hz.

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

Typical profile: Your hair straightener (flat iron) needs a voltage converter in Vietnam.

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. The cited Conair manuals describe 120V/60Hz and automatically adjusting 120/240V, 50/60Hz models. Do not broaden those ratings to 100–240V. Check your exact model and any converter prohibition; a plug adapter cannot correct an incompatible electrical supply.

Vietnam runs 220⁠V / 50⁠Hz. Vietnam runs 220V at 50Hz with sockets that commonly accept both Type A (US flat blades) and Type C (Europlug). The Type A fit is a trap: the plug goes in, but a US single-voltage device receives 220V and can overheat. Pack a Type C adapter and confirm your devices are dual-voltage.

How different input labels change this answer

Calculated examples for reading labels, not a test of your unit. Compare your actual label before using an example result.

Vietnam: 220⁠V · 50⁠Hz

120V 60Hz 50W → Voltage converter needed
100–240V 50/60Hz → Conditional compatibility
230V~ 50Hz → Check your device label first

Scope

Conair: CS4VCSR/CS19VCSR dual-voltage flat iron instructions: PDF p1, Operating Instructions / Dual Voltage: automatic 120/240 V AC, 50/60 Hz, correctly configured plug adapter. Preserve literal manufacturer rating; it does not establish 100 V support.
Conair: CS29N single-voltage flat iron instructions: PDF p1, Operating Instructions / safety item 16: 120 V AC, 60 Hz; no voltage converter.

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