Can you take a vape on a plane? Carry-on only, never checked

By Antonio Cappiello · Last reviewed 2026-09-25

Yes, in your carry-on. Vapes and spare batteries are banned from checked baggage because of fire risk, and the FAA does not allow you to use or charge one on board. Batteries must be 100 watt-hours or less, and you must stop the device switching itself on in your bag.

The short version

Your vape flies with you in the cabin. It does not fly in the hold. You may not use it or charge it once you are on board.

Those three rules cover almost every question people have, and the reason behind all of them is the same: lithium batteries.

Carry-on yes, checked baggage no

The TSA lists electronic smoking devices as allowed in carry-on bags and not allowed in checked bags. The FAA says the same thing from the other direction: these devices must be carried on your person or in carry-on baggage.

This is not a formality, and it is not about nicotine. A lithium battery that goes into thermal runaway in the cabin is a problem the crew can see and reach. The same battery in the hold, inside a suitcase, under other bags, is a problem nobody can reach until the aircraft is on the ground.

Spare batteries follow the same logic and the same rule.

The battery limit

Each lithium ion battery must not exceed 100 watt-hours. For lithium metal batteries the limit is 2 grams of lithium content.

Practically every vape sits far below that. A device with a 1,000 mAh battery at 3.7 volts is about 3.7 watt-hours, so the limit is aimed at laptops and power banks rather than at a disposable in your pocket. It is worth knowing anyway if you carry a large mod or a separate charger.

Stopping it switching itself on

The TSA requires passengers to take effective measures to prevent accidental activation of the heating element.

Draw-activated disposables are the awkward case, because there is no switch to turn off. Pressure in a bag can fire the coil, and a device that fires while buried in clothing has nowhere to put the heat. If your device has a lock, use it. If it has a removable battery or pod, separate them. Otherwise carry it somewhere it will not be squeezed.

You cannot use it or charge it in the air

The FAA does not permit recharging these devices on board, and its guidance is that they must never be used or charged on the aircraft.

Vaping in the lavatory is not a loophole. Smoke detectors are fitted there precisely because that is where people try, and disabling one is treated as a serious offence rather than a rules infringement.

A long flight is a long time between puffs. If you count your puffs on an ordinary day, you already know roughly what that gap will feel like, which is a more useful piece of preparation than most travel advice.

The rule nobody checks until it is too late

The TSA and FAA govern what happens between the security queue and the aircraft door in the United States. They say nothing about whether you may possess the device when you land.

A number of countries restrict or ban the import or possession of vapes, and the penalties are real. In the United Kingdom, single-use vapes have been banned from sale since 1 June 2025, which changes what you can replace once you are there even where carrying your own is fine.

Check the official government travel advice for your destination. A vape retailer’s blog post is not a source for whether something is legal in another country, and the airline will not warn you.

One last practical note

The TSA is explicit that the final decision rests with the officer at the checkpoint, whatever any web page says, including this one. Pack the device where you can take it out easily, keep it with the rest of your electronics, and expect the occasional swab.

Questions people also ask

Can you bring a vape on a plane?

Yes, in carry-on baggage. The TSA allows electronic smoking devices in the cabin and does not allow them in checked bags. Each lithium ion battery must be 100 watt-hours or less, or 2 grams of lithium content for lithium metal batteries, and you must take steps to stop the heating element switching on by accident while it is in your bag.

Can you put a vape in a checked bag?

No. The TSA lists electronic smoking devices as not permitted in checked baggage, and the FAA requires them to be carried on your person or in carry-on baggage. The reason is fire risk: a lithium battery fire in the hold is far harder to deal with than one in the cabin, where crew can reach it.

Can you vape on a plane?

No. The FAA does not permit recharging these devices on board and its guidance is that they must never be used or charged on the aircraft. Smoking and vaping are prohibited on commercial flights, and tampering with a lavatory smoke detector is a serious offence in its own right.

How much vape juice can you take on a plane?

E-liquid is a liquid, so in carry-on it follows the ordinary liquids rule: containers of 3.4 ounces or 100 millilitres or less, in one quart-sized bag. The TSA page for vaping devices does not set a separate e-liquid allowance. Larger bottles would normally go in checked baggage, but be aware the device and its batteries cannot.

Can you take a vape to any country?

No, and this is the part that catches people out. Several countries restrict or ban the possession or import of vapes entirely, with penalties that can include confiscation, fines or worse, and none of that is covered by the airline's rules or the TSA's. Check the official travel advice for your destination before you fly, not a vape shop blog.
