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

Q: What plug type does United States use?

United States uses Type A/B sockets at 120V / 60Hz.

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

Typical profile: Your hair straightener (flat iron) can work in United States if its actual input rating, frequency and plug match the local supply.

Conditional compatibility

Use directly only if your actual input rating covers the local voltage and frequency and your plug fits with any required grounding. A typical category profile does not confirm your own unit.

Why

Use directly only if your actual input rating covers the local voltage and frequency and your plug fits with any required grounding. A typical category profile does not confirm your own unit. 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.

United States runs 120⁠V / 60⁠Hz. Standard 120V at 60Hz. Type A is ungrounded (two flat blades); Type B adds a round ground pin. A single-voltage 220–240V appliance brought from Europe or Asia will run at roughly a quarter power or fail to start here — but it will not burn out.

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.

Final check: look for "INPUT 100-240V" or a matching local voltage on the label before you plug in.
