Can You Bring a Vape on a Plane? TSA Rules, Batteries and Vape Juice

Can you bring a vape on a plane? Yes. In the U.S., you can take a vape, a disposable or a pod kit on a flight, but only in your carry-on bag or your pocket. This guide covers the TSA vape rules and the FAA battery rules, so you can take your vape through TSA without trouble. It also covers a disposable vape on a plane, spare batteries and vape juice, plus what to check before flying with a vape abroad.

Can you bring a vape on a plane? Yes, in your carry-on

The TSA allows electronic cigarettes and vaping devices in carry-on bags, but not in checked bags. The FAA rule is the same: a vape has to travel on your person or in your carry-on. These TSA vape rules cover every kind of device, from a disposable to a box mod.

Before you pack it, though, make sure it can’t switch on by accident. The FAA’s packing page lists a few ways to do that. For example, you can take the battery out, keep the device in a case or lock the fire button. Also, check your airline’s rules, since it may limit how many devices you can bring. Finally, when you take a vape through TSA, the officer at the checkpoint makes the final call.

Why a vape can’t go in checked luggage

Vapes run on lithium-ion batteries. The FAA says these batteries can catch fire if they’re damaged or if their ends short out. In the cabin, the crew is trained to spot a battery fire and deal with it fast. A checked bag, however, sits in the cargo hold, out of reach. That’s why vapes and spare batteries have to stay with you.

So, when flying with a vape, watch for a gate check. If the crew checks your carry-on at the gate, take your vape and spare batteries out first. After all, a bag checked at the gate rides in the hold, just like any other checked bag.

Bringing a disposable vape on a plane

A disposable vape on a plane follows the same rules as any other vape, since it has a lithium-ion battery inside. Keep it in your carry-on or your pocket, and keep it from firing in your bag. If your disposable has a lock mode, turn it on before you fly. If it doesn’t, a small case or pouch helps.

Also, pack only what you need for the trip. Many disposables are rechargeable, but you can’t charge a disposable vape on the plane, so charge yours fully before you leave. To restock for the trip, browse our disposable vapes.

Spare batteries and the 100 Wh limit

If you’re flying with a vape mod that takes 18650 or 21700 batteries, you can bring spares, but only in your carry-on. The FAA says each spare must be protected so it can’t short circuit. For example, you can keep it in its retail package, tape over its ends or carry it in a battery case. A loose battery next to keys or coins can short out, so never carry one that way.

The FAA also caps each lithium-ion battery at 100 watt-hours (Wh). To find a battery’s Wh, multiply its volts by its amp-hours. For example, a 3.7-volt, 3,500mAh (3.5Ah) 18650 works out to about 13 Wh, far under the limit. Above 100 Wh, you need your airline’s OK for up to two spares, and nothing over 160 Wh can fly.

Vape juice on a plane: the 3-1-1 rule

The TSA vape rules for liquids are simple. The TSA allows e-liquids, or vape juice, in carry-on bags in bottles of 3.4 oz (100mL) or less. In checked bags, any size is fine. In your carry-on, the bottles also go in your quart-size liquids bag, with your other travel-size liquids.

So, 30mL, 60mL and 100mL bottles all fit the carry-on rule. A 120mL bottle doesn’t, though, so pack it in your checked bag. Also, lower cabin pressure can push e-liquid out of a full tank or bottle. For that reason, seal your bottles in a plastic bag, and don’t fill your tank or pod to the top before you fly.

Can you vape on the plane?

No. A U.S. Department of Transportation rule bans e-cigarettes on all scheduled flights of U.S. and foreign airlines in, to and from the U.S. The FAA puts it plainly, too: never use a vape on an aircraft.

You also can’t charge a vape or its batteries on board. So charge everything before you leave home, and pack your charger in your carry-on for the trip back.

Flying abroad with a vape

The TSA vape rules and FAA battery rules cover flights in the U.S. Abroad, however, each country sets its own vape laws, and they can be much stricter. So, before an international trip, check the laws of every country on your route, stopovers included. Also check each airline on your trip, since its limits apply even when the country’s rules allow more.

Packing checklist for flying with a vape

1. Carry-on only: pack vapes, disposables and spare batteries in your carry-on or your pocket.
2. No accidental firing: lock each device, take its battery out or put it in a case.
3. Protect spares: put each spare battery in a battery case or its retail package.
4. Bag your liquids: put bottles of 3.4 oz (100mL) or less in your quart-size liquids bag. Then pack bigger bottles in your checked bag.
5. Charge at home: you can’t charge a vape on the plane, so do it before you leave.
6. Check the extras: look up your airline’s limits and the laws where you’re going.
