Quick rule: Devices that contain installed lithium-ion cells rated under 100 Wh are generally allowed by IATA/FAA and most carriers when packed inside the device, though cabin carriage is recommended by many airlines. Spare lithium-ion cells and external power banks are prohibited in checked baggage and must travel in the cabin, protected against short circuits and movement.
Regulatory thresholds: ≤100 Wh – permitted in equipment and as spares in carry-on; 100–160 Wh – airline approval required and usually limited to two spare cells per passenger in cabin; >160 Wh – not permitted on passenger aircraft. Verify the Wh marking on the cell or product label before travel.
Preparation checklist: Power the item off; remove spare cells from checked baggage; pack spares in original boxes or protective sleeves; tape exposed terminals; keep documentation of Wh ratings handy; contact your carrier before flying if ratings fall in the 100–160 Wh band or rules are unclear.
If the unit uses primary lithium metal cells, consult manufacturer specifications and airline policy prior to departure, since many carriers apply stricter limits to non-rechargeable cells and may require cabin-only handling.
Storing powered lighting in checked baggage
Avoid placing any lighting device that contains lithium cells in hold baggage unless the power pack is permanently installed and the carrier explicitly permits it; otherwise carry the item in your cabin bag.
Regulatory thresholds and typical airline practice
Rechargeable lithium-ion cells: devices whose cells are rated under 100 Wh are commonly accepted when installed in equipment, but many airlines prefer they travel in the cabin. Cells rated between 100 Wh and 160 Wh require airline approval and are often restricted to cabin only; cells over 160 Wh are prohibited on passenger flights. Non-rechargeable lithium metal cells are limited by lithium content per cell (commonly ≤2 g Li per cell and ≤5 g per battery) and are generally allowed only in hand baggage under strict limits.
Packing steps and documentation
Before travel: verify the airline’s dangerous-goods page and local aviation authority rules; confirm Wh or lithium content markings on the power source. Power the device off and prevent accidental activation by removing switches, covering controls, or using a hard case. If removal of cells is possible, carry removed cells in cabin in individual insulating sleeves or original packaging; terminals must be taped or otherwise protected. For spares between 100–160 Wh seek written airline approval ahead of travel. Declare large or atypical power packs at check-in when requested.
Safety note: fires originating from energy cells in the hold cannot be directly suppressed by cabin crew, increasing the risk of loss and insurance complications; when in doubt, carry the device onboard or ship via a specialized cargo service that accepts dangerous goods.
Which power-cell chemistries are permitted in hold baggage?
Keep spare lithium‑ion and lithium‑metal cells in the cabin; only cells installed inside a device are normally allowed in hold baggage and then subject to airline rules.
Numeric limits and airline rules
Lithium‑ion (rechargeable): cells rated ≤100 Wh are acceptable in the cabin as spares and may travel installed in devices in the hold depending on the carrier. Cells 100–160 Wh require airline approval and are typically limited to two spare units in the cabin; >160 Wh are forbidden on passenger aircraft. Always verify the Wh rating printed on the cell or device; common examples: smartphones and most laptops are <100 Wh, many large power banks exceed 100 Wh and need approval.
Lithium‑metal (non‑rechargeable): spare lithium‑metal cells are not permitted in the hold and must travel in the cabin if allowed at all. Cells containing >2 g elemental lithium are prohibited on passenger aircraft. Devices that house lithium‑metal cells can sometimes be stowed in the hold but check the airline’s policy first.
Alkaline and other non‑lithium chemistries (AA, AAA, C, D, NiMH): accepted in hold baggage without special approvals; standard precautions against accidental activation are sufficient.
Packing checklist and practical steps
1) Carry all spare lithium‑ion and lithium‑metal cells in hand luggage only; protect terminals with tape or original packaging to prevent short circuits. 2) Power devices off and secure any activation switches before stowage. 3) If a device’s cell exceeds 100 Wh, obtain written airline approval in advance. 4) Keep manufacturer markings or documentation for Wh or lithium content available for inspection. 5) For devices that must travel in the hold, use a rigid case to reduce mechanical damage – consider best luggage set hard shell.
Preparing a power-cell–powered portable light for checked baggage: power-off, terminal protection, secure mounting
Remove removable power cells and transfer them to carry-on; for integrated cells, render device inoperative and isolate exposed contacts.
-
Power-down procedures
- Hold the power control until all indicators extinguish and device remains cold to the touch for at least 30 seconds.
- If a removable pack exists, extract it and store in cabin carry-on in original packaging or individually capped sleeves.
- For non-removable packs, disconnect internal connector if accessible, or use a rigid non-conductive spacer to block the switch travel.
-
Terminal and contact protection
- Cover each exposed terminal separately using molded plastic caps, heat-shrink tubing, or two wraps of electrician’s tape; avoid a single continuous wrap that could bridge terminals.
- Label taped terminals “DO NOT CONNECT” in plain text on adhesive tape to alert handlers.
- Secure spare cells carried in cabin so terminals cannot contact metal objects; use individual terminal caps or original cell packaging.
-
Secure mounting inside checked baggage
- Place device in a hard-sided case or a rigid insert; surround by closed-cell foam cut to fit the profile and prevent rotation.
- Anchor heavy assemblies using nylon straps or cable ties to internal luggage anchor points; avoid compression between heavy items that could deform case or press switches.
- Position device centrally, away from suitcase walls and heat sources; fill voids with soft clothing to absorb shock.
- For long stands or poles, use a tube or sleeve and strap that assembly to the suitcase frame rather than laying loose across contents; for examples of durable outdoor poles and related packing ideas see best wind resistant patio umbrella south florida.
Quick checklist:
- Removable cells removed and carried on board
- All switches taped or blocked; indicators dark
- Terminals individually insulated
- Device immobilized inside a rigid container and cushioned
- Label applied if terminals taped or device rendered inoperative
Spare or loose cells and portable chargers in checked baggage: immediate instruction
Do not place spare cells or portable chargers in checked baggage; carry all uninstalled lithium cells and external power packs in the cabin compartment only.
Regulatory summary: IATA, FAA and TSA classify spare lithium-ion and lithium metal cells, plus external chargers/power banks, as cabin-only items. Non-lithium chemistries such as alkaline or NiMH are generally allowed in checked baggage but contacts must be insulated.
Capacity and approval thresholds (apply to spare/uninstalled units only): lithium-ion cells/packs – up to 100 Wh allowed per unit in cabin; 100–160 Wh allowed only after airline approval and limited to two spare units per passenger; greater than 160 Wh prohibited on passenger aircraft. Lithium metal cells – allowed in cabin if lithium content ≤2 g per cell; cells containing >2 g lithium are forbidden on passenger aircraft.
| Item type | Allowed in checked baggage? | Action |
|---|---|---|
| Lithium‑ion cells / packs | No | Carry in cabin; if 100–160 Wh obtain airline approval before travel; >160 Wh not permitted |
| Lithium metal cells (primary) | No | Carry in cabin only if lithium content ≤2 g per cell; >2 g prohibited |
| Power banks / portable chargers (Li‑ion) | No | Treated as lithium‑ion packs; carry in cabin; check Wh rating for airline approval requirements |
| Alkaline, NiMH, NiCd cells (spare) | Generally yes | Terminals insulated; some carriers still request carriage in cabin – verify airline policy |
How to check capacity: convert mAh to Wh using Wh = (mAh × V) / 1000. Example: a 20,000 mAh power bank rated at 3.7 V equals 74 Wh (20,000 × 3.7 / 1000 = 74).
Declare and obtain approval for any units in the 100–160 Wh band before travelling; failure to follow rules may lead to removal of items, denied boarding or fines. Keep spares accessible for inspection; secure terminals by taping or using original packaging.
How to verify airline and country-specific power-cell rules before traveling
Confirm carrier policy and both origin and destination civil aviation authority rules at least 72 hours before departure; obtain written airline approval for power cells rated above 100 Wh or for lithium-metal chemistry.
Quick verification checklist
1) Airline hazardous-goods page: search “[airline name] dangerous goods” or “[airline name] hazmat policy” and read the section describing permitted items in the passenger cabin and aircraft hold. Low-cost carriers and regional operators often impose stricter limits than major carriers.
2) IATA reference: consult the IATA Dangerous Goods Regulations (DGR) for standard passenger limits (≤100 Wh generally allowed in cabin; 100–160 Wh may require airline approval). The DGR is the primary industry baseline; carriers may adopt tighter rules.
3) National regulators: check FAA (USA), EASA (EU), UK CAA, CASA (Australia), CAAC (China) and any transit-country authority pages for prohibitions or added documentation requirements. Some states prohibit certain chemistries from cargo, even if allowed in cabin.
4) Identify rated energy: look for a printed Wh value on the cell or power pack. If only voltage (V) and capacity (mAh or Ah) are shown, calculate watt‑hours: Wh = V × Ah (example: 3.7 V × 2.6 Ah = 9.62 Wh). If markings are absent, download the manufacturer datasheet or treat the item as unverified and request carrier guidance.
5) Transit routing: verify rules for all connecting carriers and countries on the itinerary. A routing that is acceptable for the departure carrier may be restricted by a transit state’s regulator or by the transit carrier’s policy.
6) Documentation and proof: if airline approval is required, request written confirmation by email and print a copy to present at the ticket counter and at boarding. Screenshot alone may be rejected by some agents; an official reply from the carrier customer-service address is preferred.
How to contact the carrier and what to ask
Email subject suggestion: “Hazardous goods query – power-cell approval for checked or cabin carriage”. In the body list device model, printed energy markings (Wh or V and mAh), number of cells, intended packing location (hand baggage or aircraft hold), and full itinerary including transit points. Ask for explicit permission and any handling instructions the agent at the airport must follow.
If time allows, call the carrier’s hazardous-goods desk and request a reference number for the approval. At the airport, present the printed approval, device and product spec sheet to the ticket agent before handing the item to hold staff.

What to do at the ticket counter if staff question or refuse a powered light
Request a written policy reference and ask to speak with a supervisor immediately.
Immediate steps to take at the counter
Present the product label and manufacturer specification sheet showing voltage and capacity; calculate watt-hours using Wh = (mAh × V) / 1000 (example: 2600 mAh × 3.7 V = 9.62 Wh). Photographs of the label and online product page help.
Power the device off, isolate terminals with non-conductive tape, and place the unit in a protective pouch or hard case before further handling. Offer to remove internal or external power cells and carry them in the cabin if airline policy permits.
Ask staff to cite the exact airline or regulatory clause being applied (airline policy name/section, IATA DGR or national aviation authority reference). Request that any refusal be issued in writing, including staff name, supervisor name, time and reason for refusal.
Options if refusal is upheld
Choose one of these documented alternatives: 1) Ship the item as air cargo under hazardous goods procedures through the airline cargo desk or a specialised courier; 2) Dispose or surrender the unit at the airport’s hazardous waste point if available; 3) Remove power cells entirely and travel without them.
If shipping as cargo, obtain the shipper’s declaration, tracking number and a written acceptance note referencing IATA DGR requirements. If the airline will not accept shipment, contact a freight forwarder experienced in hazardous goods.
Keep all written refusals, receipts and time-stamped photos; if you believe policy was misapplied, file a formal complaint with the airline and, if relevant, with the national aviation authority, attaching the documentation collected at the counter.
