Using it abroad

Hair Straightener (Flat Iron)

Do not connect this device to incompatible voltage. A plug adapter cannot correct it. For high-power heating, PlugVoltage recommends a suitably rated local appliance or a manufacturer-approved travel model instead of travel conversion.

Check your device label first

Check your label first.

Compatibility is unconfirmed. Read the exact INPUT voltage range and frequency on your device or power supply, and compare them with the destination. The whole local range must be covered; 110–220V does not include 100V or 230–240V. Confirm the actual plug, grounding and manufacturer restrictions. Do not plug in while these details are unknown.

How to read the INPUT label

Read the INPUT rating on the exact device or AC supply: V = voltage, Hz = frequency, A/W = current/power. USB/DC OUTPUT ratings are not the AC input range or measured wall consumption. Match the full local voltage and frequency, plug, grounding and manufacturer instructions. A 100–240V label covers only that range; 120–240V does not include Japan’s 100V. If the label is missing or unclear, do not connect until confirmed.

Model facts and sources

Document scope: Models CS4VCSR/CS19VCSR in CS4GNR booklet; 120/240V discrete wording is preserved.

Automatic adjustment between the stated 120/240V ratings is not a continuous 120–240V claim. The document alone does not approve 230V or 100V. Converter permission, watts and grounding remain unknown.

FAQ

Is my hair straightener (flat iron) dual voltage?

Check the actual input label on your hair straightener (flat iron) or its power supply. A 100-240V range covers those voltages; confirm frequency, grounding and model instructions separately. Category examples do not verify your own unit.

Can I use my hair straightener (flat iron) in Europe?

Only when the actual input rating covers the destination voltage and frequency and the plug fits with required grounding. For a medical device, confirm the exact supply and accessories with its manufacturer.

Do I need a voltage converter for my hair straightener (flat iron)?
