Immediate recommendation: Store all vaporizers, pods and spare cells in cabin carry-on; checked baggage storage is disallowed by most aviation authorities. Devices must be powered off, tanks emptied or sealed, and any child‑lock or safety switch engaged to prevent accidental activation and leakage.
TSA, IATA and EASA rules classify electronic nicotine delivery systems as permitted only in cabin baggage. Spare lithium‑ion batteries are required in the cabin: batteries under 100 Wh are allowed without airline approval; batteries between 100–160 Wh require airline permission; batteries exceeding 160 Wh are prohibited on passenger flights.
Refill liquids and cartridges must follow standard liquid screening: individual containers not exceed 100 ml, all placed inside a single transparent resealable bag with total capacity up to 1 L. Several countries impose limits or bans on nicotine concentrations and importation of nicotine solutions; verify destination regulations ahead of departure.
Practical packing tips: keep spare cells in protective sleeves or original packaging, insulate terminals with tape, carry devices separately for inspection and retain proof of battery Wh rating. Charging onboard is typically forbidden and in‑flight vaping is banned by almost all carriers. To estimate energy, use Wh = V × Ah; example: 3.7 V × 3 Ah = 11.1 Wh.
Vape-device rules for carry-on
Pack all vaping devices and spare lithium batteries only in carry-on; never place them in checked baggage.
Battery rules
TSA and IATA guidance: electronic vaping devices must remain in the cabin; checked baggage storage for these devices is prohibited. Spare lithium-ion batteries must be carried in the cabin, with terminals insulated (tape over contacts or use individual battery cases). Batteries below 100 Wh are permitted without airline approval. Batteries between 100 Wh and 160 Wh require airline approval and are usually limited to two spare units per passenger.
To calculate watt-hours: Wh = (mAh / 1000) × V. Example: a 3000 mAh cell at 3.7 V equals 11.1 Wh – well under the 100 Wh limit.
Liquids, operation and destination bans
E-liquids fall under standard cabin liquid rules: containers must be ≤100 ml (3.4 fl oz) and fit inside a single 1 L resealable clear bag for screening. Tanks should be capped and secured; consider emptying tanks for transit if risk of leakage exists. Devices must be powered off, protected against accidental activation, and not charged or used onboard.
Several countries forbid importation or possession of vaping devices and e-liquids (examples: Singapore, Thailand, Brunei and some Gulf states); penalties can include confiscation, fines or detention. Verify airline policy and destination customs regulations before departure to avoid seizure or legal issues.
Quick checklist: carry devices and spare batteries in cabin, insulate battery terminals, keep liquids within 100 ml inside a 1 L bag, power devices off, do not use or charge onboard, and confirm airline plus destination rules ahead of travel.
Which airlines and countries permit electronic vaping devices in carry-on bags?
Keep electronic vaping devices and spare lithium batteries in cabin baggage; placement in checked baggage is restricted or forbidden by most airlines.
IATA/ICAO rules applied by most carriers: lithium-ion cells up to 100 Wh are allowed without airline approval; cells between 100–160 Wh require airline approval and are typically limited to two spares per passenger; cells above 160 Wh are generally prohibited. Spare batteries must have terminals protected (tape or original packaging) and be carried in the cabin.
Examples of major carriers with permissive cabin policies (battery rules apply): American Airlines – devices and spares allowed in cabin only; Delta – cabin only, charging usually disallowed; United – cabin only, approval required for 100–160 Wh; British Airways – cabin only, no checked stowage; Lufthansa, Air France, KLM – cabin only, follow IATA Wh limits; Emirates, Qatar Airways – cabin only, approval often required for >100 Wh; Singapore Airlines – cabin only with battery protections; Ryanair, easyJet – cabin carriage permitted within Wh limits.
Country-level practice: United States, European Union states, Canada and Australia adopt IATA guidance and enforce cabin-only carriage for devices and spares; China and India impose strict enforcement and penalties for violation; some Middle Eastern jurisdictions require advance declaration for batteries above standard limits.
Actionable checklist before travel: verify battery Wh rating printed on battery; obtain airline approval for 100–160 Wh items; place spares in individual plastic bags or original packaging and tape terminals; power devices off and protect tanks/atomizers against leakage; consult the specific carrier’s official policy and the departure/arrival country aviation authority prior to departure.

Packing lithium batteries and spare cells for vape devices in carry-on
Store spare lithium-ion and lithium-metal cells only in cabin baggage; spares are prohibited in checked baggage.
Regulatory limits
Lithium-ion: ≤100 Wh – no airline approval normally required; 100–160 Wh – airline approval required and maximum two spare batteries; >160 Wh – forbidden as spares. Lithium-metal (non-rechargeable): maximum lithium content 2 g per cell for carriage as spare; cells with >2 g lithium content are not permitted.
Wh conversion and common examples
Use Wh = (mAh ÷ 1000) × nominal voltage (typically 3.6–3.7 V). Examples: 18650 at 3000 mAh → ~11.1 Wh; 21700 at 4000 mAh → ~14.8 Wh; a 20,000 mAh power bank (5 V output rating aside) usually lists Wh on the unit – if not, convert using nominal cell voltage. Power banks are treated as spare lithium batteries and follow the same Wh rules.
Step-by-step packing: remove cells from devices when batteries are removable; power off all devices with internal batteries and ensure no activation mechanism can engage. Insulate terminals with electrical tape or use purpose-made plastic battery sleeves; store each cell in an individual hard or plastic case or original retail pack. Place cases inside carry-on in a location accessible for inspection. Avoid loose loose-contact arrangements and prevent contact with metal objects.
Additional precautions: damaged, swollen, taped-over, shorted or modified cells are forbidden. For batteries between 100–160 Wh obtain documented airline approval before travel and limit spares to the approved quantity (usually two). Airline and airport operators may impose stricter limits; verify carrier policy and local regulations before departure. If a declaration is required, present batteries at check-in rather than attempting transport in checked baggage.
E-liquid limits, container rules and leak-proof packing for carry-on
Keep each e-liquid bottle ≤100 ml (3.4 fl oz) and place all bottles inside a single transparent resealable bag no larger than 1 litre/1 quart for security screening.
Most airports apply the 100 ml-per-container rule for cabin carriage; bottles larger than 100 ml are usually restricted to checked baggage where local regulations allow. Verify destination rules for nicotine concentrations and import restrictions prior to departure.
Prefer original retail bottles with clear volume markings and visible nicotine-strength labels. If decanting, use rigid travel bottles clearly marked with capacity; avoid soft squeeze bottles without positive-lock caps. Apply a short wrap of PTFE (plumber’s) tape around the thread before screwing the cap to improve seal integrity.
Leak-proof packing technique: seal each bottle inside a small zip-top pouch, expel excess air, then combine pouches into one 1-litre resealable bag with an absorbent cloth or paper towel. Place the sealed bag upright in a hard-sided toiletry case or molded compartment to reduce movement and pressure-related seepage. Store the sealed 1-litre bag in a compact cabin compartment such as a toiletry pouch or an best edc waist pack; for multi-leg trips consider a rigid case featured in best luggage for bus travel.
At security, present the sealed 1-litre bag separately for inspection. Unlabeled, overfilled or poorly packed bottles are likely to be removed. Keep purchase receipts or original packaging accessible to confirm contents if requested.

Store upright in a hard-sided toiletry case or compact carry compartment; present the 1-litre bag separately at screening.
Airport security checks and airline policies on charging or using vaping devices in flight
Do not operate or recharge vaping devices during flight; most carriers and aviation authorities prohibit in‑flight use and many forbid in‑seat charging of such devices.
- Screening and inspection: Security staff commonly require removal of vaping devices from cabin bags for X‑ray; devices with visible damage, leaking tanks or swollen batteries are frequently refused boarding. Officers may request powering on to prove functionality; failure to do so can lead to device retention.
- Checked baggage restriction: Major regulators (including TSA and EASA guidance) disallow electronic nicotine-delivery devices in checked bags due to fire risk; keep devices and spare cells in cabin baggage for screening and access.
- Spare batteries and power banks: Spare lithium batteries and power banks must be carried in the cabin and protected against short circuits (terminal taping, original packaging, or individual cases). Capacity limits: ≤100 Wh allowed without airline approval; >100 Wh up to 160 Wh requires airline approval; >160 Wh is typically forbidden.
- Conversion guidance: Convert milliampere‑hours to watt‑hours via Wh = (mAh ÷ 1000) × V. Example: a single 18650 cell at 3.7 V and 2500 mAh ≈ 9.25 Wh; a 20,000 mAh power bank ≈ 74 Wh (20 Ah × 3.7 V).
- Onboard charging and use: Even where cabin power outlets exist, crew instructions usually prohibit charging vaping devices. Operating a device mid‑flight, or in a lavatory, risks immediate intervention, fines, diversion of the aircraft and possible criminal charges under many national laws.
- Smoke and fire detectors: Lavatory smoke detectors are highly sensitive; activation due to vaping often triggers emergency procedures and heavy penalties. Avoid any attempt to use devices inside terminal restrooms or aircraft lavatories.
- When asked by security or crew: Provide devices for inspection, power them on only if requested, and surrender damaged items if required. Follow crew directions; refusal to comply may result in removal from flight and regulatory enforcement.
- Documentation and pre‑flight checks: Check battery Wh markings and airline policy before travel; retain manufacturer labels for high‑capacity cells and seek airline approval for batteries rated 100–160 Wh. Report any physical defects to security staff prior to screening.
Strict adherence to these rules minimises seizure risk, regulatory fines and safety incidents; always consult the specific carrier and departure/arrival authority for any additional prohibitions or approval requirements.
