A hair straightener with a cord travels in a checked bag with no restriction. Are hair straighteners allowed in checked baggage if they run on a battery instead? Not anymore.
The same corded versus cordless split decides hair dryers, curling irons, beard trimmers, electric shavers, and electric toothbrushes. Most tools in a bathroom drawer are corded, so most readers can stop worrying right here. The exceptions are the ones bought specifically for travel: cordless flat irons, butane curling irons, and battery packed trimmers.
Corded hair tools face no restriction at all
A corded hair dryer, flat iron, or curling iron counts as an ordinary electric appliance. It can go in a checked bag or a carry-on. No size limit applies, no watt limit applies, and no form needs filling out.
The same holds for a corded beard trimmer or a plug in electric shaver. This is the answer most searches on this topic are really after. Check the full electronics rules for anything else in the bag.
The one real exception: butane curling irons
Some curling irons run on a small butane cartridge instead of electricity. That is how a stylist heats one with no outlet nearby.
Are hair straighteners allowed in checked baggage when the tool runs on gas the same way? No, and neither is the curling iron version.
The FAA allows a butane curling iron in a carry-on only, one per passenger. It needs a safety cover fitted over the heating element to block accidental activation. A checked bag is off the table entirely.
Spare gas cartridges are banned outright in either bag. Only the single cartridge already loaded inside the iron travels with you. It stays in the carry-on, where an officer can look at it if asked.
Cordless tools and the lithium battery rule
A cordless flat iron or curling iron with a lithium battery now follows the butane rule. TSA tightened this in 2025 after reports of a cordless iron switching itself on inside a suitcase.
So are hair straighteners allowed in checked baggage when they run on a battery instead of butane? No, they must fly in the cabin too.
The reasoning is specific to the heating element, not the battery on its own. A cordless flat iron or curling iron needs the same safety cover as the butane version. That cover goes over the plates or barrel before the tool clears a checkpoint.
Other cordless personal care items carry no such restriction. None of them has an exposed heating element, so a small sealed battery is fine in a checked bag. A battery pack that pops out and travels loose counts as a spare, so it belongs in your carry-on.
Electric shavers and trimmers are not sharp objects
Blade razors have their own strict rule. A disposable cartridge razor is fine in a carry-on, but a fixed blade version goes in the hold. Electric shavers and trimmers skip that category, since neither one has an exposed blade.
An electric shaver, beard trimmer, or nose hair trimmer can travel in either bag, with no special handling. Anyone unsure where a blade item lands can check the sharp objects rules before packing a mixed toiletry bag.
Travel adapters and voltage: why a legal hair dryer still fails abroad
A hair dryer can be perfectly legal to pack and still die the moment you land overseas. That is a voltage problem, not a security rule. Most US hair dryers run on 120 volts, while Europe, Asia, and Africa often run on 220 to 240.
A plug adapter only changes the shape of the prongs. It does nothing to convert the current. A single voltage dryer plugged into the wrong current can burn out in seconds.
Some flat irons and curling irons are built dual voltage and switch automatically. Check the label near the cord before an international trip rather than guessing. A dryer that packed fine for Rome can still die the moment you plug it in.
Packing to avoid heat damage and an accidental switch flip
A hot styling tool packed straight off the counter can scorch clothing or melt a plastic pouch. Let it cool for a few minutes first. Use a heat resistant sleeve or the tool’s own travel case if it came with one.
Lock the power switch or slide the safety cover into place, even on a corded tool. A switch bumped inside a packed checked bag can run for hours before anyone notices. Run a mixed bag of chargers and styling tools through the packing list screener before airport security.

Common questions
Are hair straighteners allowed in checked baggage if they are cordless?
No. A cordless flat iron with a lithium battery has to travel in a carry-on. It also needs a safety cover fitted over the plates to clear screening.
Can I bring a butane curling iron on a plane at all?
Yes, but only in a carry-on, only one per passenger, and only with the safety cap in place. Spare gas cartridges cannot go in either bag.
Do I need to remove the battery from an electric shaver before checking a bag?
No. A sealed battery built into a shaver or a toothbrush is fine in a checked bag. Only a loose, removable battery pack needs to travel in your carry-on instead.
Why did my hair dryer stop working on an international trip?
Most likely a voltage mismatch, not an airline rule. A single voltage US dryer plugged into a 220 to 240 volt outlet can burn out almost instantly.
Are electric shavers treated as sharp objects at security?
No. An electric shaver or trimmer has no exposed blade. That means it skips the razor rule for disposable and safety razors.
Can a portable travel fan go in checked luggage?
Usually yes, since most battery powered travel fans use a small sealed battery well under any watt hour limit. Carrying it on instead only matters if you want to protect it from rough handling.
