Yes. You can bring a cordless hair straightener on a plane in your carry-on bag, but not in checked luggage. TSA allows battery-powered (lithium) and butane models in the cabin only, with a safety cover over the plates and protection from switching on. Spare gas cartridges aren't allowed at all. Corded flat irons can go in either bag.
Rules checked: October 2026. The final decision rests with the TSA officer.
The short answer: carry-on yes, checked bag no
| Tool type | Carry-on | Checked bag |
|---|---|---|
| Cordless (lithium / rechargeable) | Yes, with special instructions | No |
| Butane or gas-powered | Yes, one per person | No (spare gas cartridges not allowed in either bag) |
| Corded (plugs into an outlet) | Yes | Yes |
What TSA says about cordless straighteners
TSA's Hair Straightener, flat iron (cordless) page lists carry-on bags as "Yes (Special Instructions)" and checked bags as "No":
"Cordless hair straighteners that contain lithium metal or lithium ion batteries or are gas or butane fueled are only allowed in carry-on bags. A safety cover must be securely fitted over the heating element. The device must be protected from accidental activation." "Gas refills (spare cartridges) are not permitted."
The same rule applies to cordless curling irons. Corded tools are different: TSA's complete list says hair straighteners with cords "are not restricted unless they also include batteries or gas/fuel cartridges."
What the FAA says about lithium batteries and butane
Batteries installed in the device
Most cordless straighteners have a built-in rechargeable lithium-ion battery. Keep the device in your carry-on, switched off and locked. See the FAA's guide to portable electronic devices containing batteries.
Spare batteries and power banks
The FAA's lithium battery rules say spare lithium batteries and power banks go in carry-on baggage only. If your carry-on is checked at the gate or planeside, take them out and keep them with you in the cabin. Protect the battery terminals from short circuits.
Size limits
Lithium-ion batteries are limited to 100 watt hours (Wh) per battery and lithium metal batteries to 2 grams of lithium (TSA). Those limits cover nearly all batteries in personal devices. Check your tool's specs if you're unsure.
Butane straighteners and gas refills
The FAA's PackSafe page for cordless curling irons allows one butane or gas-cartridge tool per person, in carry-on baggage only, with a safety cover over the heating element. Gas refills (spare cartridges) are not permitted.
Can I put my straightener in my checked bag?
Only if it's corded with no battery or gas cartridge. Cordless lithium and butane tools must go in your carry-on. Spare or removable batteries come out and travel in the cabin with you.
How to pack a cordless straightener for security
- Let it cool completely before packing.
- Fit the heat cover or pouch over the plates.
- Use the power lock, or switch it fully off, so it can't turn on in your bag.
- Keep the charging cable with it.
- Charge it before you fly: TSA says officers may ask you to power up electronic devices, and devices that won't power on may not be allowed on board.
Flying internationally with a flat iron
Airline and country rules vary
The FAA itself advises checking with your airline on international flights, since rules can differ from US domestic rules.
Voltage
US outlets supply 110–120V. A tool rated only for 220V won't work properly in the US without a suitable converter. Dual-voltage (110–240V) tools work in both. USB-charging tools avoid the problem.
Travel straightener buying checklist
- Power type clearly stated (lithium/rechargeable, USB, corded or butane)
- Battery capacity (mAh or Wh) listed
- Heat-resistant cover or pouch for the plates
- A lock or power button that prevents accidental switch-on
- USB or USB-C charging
- For corded tools: rated voltage (110–120V for the US, 110–240V for international trips)
- Adjustable temperature. Start low and use a heat protectant
- A size that fits your carry-on or personal item
