Hamad International (DOH) and Qatari operators follow ICAO/IATA lithium-ion battery guidance: installed batteries inside devices and spare external packs must travel in cabin baggage only; checked baggage is not acceptable for spare cells. For packs between 100–160 Wh approval from the airline is required before travel; most carriers limit approved spare units to a maximum of two per passenger in that range.
Convert milliamp-hours to watt-hours using the formula Wh = (mAh × V) / 1000. If voltage is not printed, assume 3.7 V for typical cells. Examples: a 10,000 mAh pack ≈ 37 Wh, 20,000 mAh ≈ 74 Wh, 27,000 mAh ≈ 99.9 Wh, 48,000 mAh ≈ 177.6 Wh (which exceeds the passenger limit).
Packing and security checks: terminals must be protected against short circuits (tape over terminals or original packaging), each unit should be individually protected from damage, and spare units must be accessible for inspection. Declare any unit above 100 Wh to the airline at booking or check-in and retain approval documentation. When in doubt, contact the carrier or the airport’s security office at DOH before traveling to avoid confiscation or denied boarding.
Portable battery-pack rules for cabin carriage in Doha
Recommendation: keep all spare lithium battery packs in cabin baggage; devices with batteries installed are permitted but storing them in the cabin reduces risk and inspection time.
Regulatory thresholds: lithium‑ion cells up to 100 Wh are allowed in cabin without prior approval; units between 100 Wh and 160 Wh require airline approval and are normally limited to two per passenger; cells above 160 Wh are forbidden in both cabin and checked hold.
How to verify capacity: use Wh = V × Ah (for mAh convert to Ah by dividing by 1,000). Examples: 5,000 mAh at 3.7 V = 18.5 Wh; 20,000 mAh at 3.7 V = 74 Wh; 27,000 mAh at 3.7 V ≈ 99.9 Wh. If Wh is not printed on the unit, carry the manufacturer specification or a printed calculation.
Packing and protection: isolate terminal contacts (apply tape or use original caps), store each unit in its own protective pouch or hard case, avoid loose placement inside checked suitcases, and keep devices powered off. Security checkpoints may request removal from bags for inspection; unmarked or damaged units can be seized.
Approval and documentation: contact the carrier operating from Doha before travel if any unit exceeds 100 Wh. Approval usually requires a written confirmation (email or stamped form) including model and Wh rating; present that document at check‑in.
Small insulating accessories (terminal caps, protective rings) help prevent short circuits; sourcing examples and small sealing parts can be found at best pressure washer o rings.
If uncertainty exists about several spare packs or high‑capacity units, either leave extras at home or arrange regulated cargo shipment with proper declaration; noncompliance can result in confiscation, fines, or denied boarding.
Allowed watt‑hour ranges for spare lithium battery packs under national aviation rules
Allowed ranges: ≤100 Wh – permitted without carrier approval; 100–160 Wh – allowed only with written airline approval (maximum 2 spare units per passenger); >160 Wh – prohibited as spare items on passenger aircraft and accepted only as cargo under special dangerous‑goods procedures.
Labeling and calculation: Wh rating must be displayed on the cell or pack. If only mAh and voltage are shown, calculate Wh as Wh = (mAh × V) / 1000. Packs without a readable Wh figure are subject to inspection and possible refusal.
Documentation and limits: Units in the 100–160 Wh band require prior written authorisation from the carrier; that authorisation should cite the exact Wh ratings and quantities. For ≤100 Wh items most carriers apply no formal approval but may impose a quantity cap – consult the specific airline policy for firm limits.
Handling and protection: All spare lithium items must have terminals insulated (original packaging, terminal covers, or non-conductive tape) and be individually protected against short circuits; damaged or modified cells are likely to be rejected.
| Watt‑hour range | Status under national aviation rules | Max spare units per passenger | Approval required | Notes |
|---|---|---|---|---|
| ≤ 100 Wh | Permitted as spare items | No standard international limit (carrier may restrict) | No | Label usually present; terminals must be protected |
| 100–160 Wh | Permitted with restrictions | Up to 2 | Written airline approval | Pack must show Wh rating; airline may request documentation |
| > 160 Wh | Prohibited as spares on passenger flights | 0 (passenger) | No standard passenger approval – cargo only under DG rules | Transportable only via regulated cargo shipment with dangerous‑goods paperwork |
Airline carry-on policy: portable charger limits, quantity and placement
Store all spare lithium external battery packs in cabin baggage only; checked baggage carriage of loose cells is prohibited.
Units that exceed the carrier’s standard capacity threshold require prior approval from the airline and are typically limited to two spares per passenger; present manufacturer labeling or technical documentation at check‑in when requesting approval.
Devices with built-in rechargeable cells are accepted in either cabin or checked bags, but keeping the device in the cabin is recommended for rapid access during screening and for crew inspection if needed.
Each spare pack must have terminals insulated (tape over terminals, original retail packaging, or individual plastic sleeves) and be stored so contacts cannot touch metal objects or other batteries. Keep spare units separate from loose metal items, and avoid stacking multiple packs together in a single pocket.
Multiple small-capacity units intended for personal use are generally permitted, but distributing them between carry‑on compartments (under seat and overhead) reduces risk and speeds security checks. If screening requires demonstration, be prepared to power on a device containing the cell.
Documentation and declarations
Carry product labels showing Wh or Ah and voltage; if approval is needed, declare at check‑in and retain written airline confirmation. Without documentation, approval may be denied and the item refused.
Damage, leakage and crew directions
Damaged, swollen or leaking cells will be refused; follow crew instructions and security staff directions immediately. Non‑compliance can result in refusal of carriage or confiscation.
How to prepare, label and pack external battery packs for Doha security screening
Label every external battery pack with its watt‑hour rating (Wh); if Wh is not printed, calculate using (mAh ÷ 1000) × V and mark the result alongside the mAh and voltage (example: 37 Wh – 10000 mAh, 3.7 V).
Labeling
Use a permanent marker or affix a printed label showing: Wh, mAh, voltage and manufacturer/model. If the unit surface is curved or glossy, attach a small laminated tag with a zip tie or strong adhesive. For aftermarket cells that lack manufacturer data, include the calculation used and a copy of the retailer/spec sheet.
Format example for inspection staff: “37 Wh – 10000 mAh – 3.7 V – Model X123”. Place one label on the unit and one on the outer packaging or clear resealable bag.
Packing and presentation at security
Insulate all exposed terminals using electrical tape or dedicated terminal caps; avoid loose metal objects nearby. Store each battery pack in its own clear resealable bag or original retail box and keep items separate from mobile devices (no stacking inside a single device pouch).
Keep all battery packs in cabin baggage and make them readily accessible for X‑ray or manual inspection; remove from bags and place on the tray when requested. Carry printed manufacturer specs or a screenshot showing Wh and mAh; for units that required prior airline approval, bring the approval email or printout to present to check‑in/security staff.
Power off packs and disable passthrough charging features before screening. For damaged, swollen or modified cells, do not present for travel – hand to airline/security staff for direction.
Declaration requirements and when to seek airline approval before departure
Declare lithium‑ion spare battery packs above 100 Wh to the carrier and airport security prior to departure; approval is mandatory for items between 100 Wh and 160 Wh, and items over 160 Wh require written airline authorization or will not be accepted on passenger services.
Required steps before check‑in
- Confirm Wh rating printed on the cell or casing. If only mAh shown, convert using: Wh = (mAh ÷ 1000) × V (use nominal voltage, typically 3.7 V).
- Contact the carrier at least 48 hours before scheduled flight for any single spare cell >100 Wh or for quantities exceeding standard allowances.
- Obtain written approval (email or printed permit) for 100–160 Wh items and present it at check‑in and security checkpoints.
- Standard limit: maximum two spare items in the 100–160 Wh range per passenger unless the airline states otherwise.
- Do not place spare cells in checked baggage; items must remain in the cabin with the passenger and terminals must be protected against short circuit (tape over terminals or use original packaging).
Special cases: high‑capacity cells and medical/mobility equipment
- Cells exceeding 160 Wh are typically restricted to cargo only; arrange transport through the airline’s dangerous goods or cargo desk well before the planned travel date.
- Batteries installed in medical or mobility devices require prior approval and supporting documentation (manufacturer specifications, medical certificate). Aim to secure authorization 72 hours or more in advance.
Failure to declare high‑capacity cells at check‑in or security can result in confiscation, boarding denial or significant delay. For carrier‑specific limits and contact points use the airline’s dangerous goods or special assistance channels before departure.

Practical steps if an external battery is denied at check-in or confiscated at the gate
Request a written confiscation or denial receipt on the spot that includes agent name, agency/airline, date/time, precise reason for action and a reference or case number.
Photograph the device, model and serial numbers, the manufacturer label showing watt‑hour or mAh rating, original packaging and any on‑screen airline or regulatory guidance. Retain boarding pass, ID and baggage tags; scan or photograph them immediately.
If denied at check‑in, escalate to a supervisor and present the device specification sheet (PDF or screenshot) and any prior written airline approval. Refuse transfer to checked baggage unless the item is permanently installed in equipment and the airline/security explicitly authorises checked carriage in writing.
If seized at the gate, obtain the seizure tag or evidence slip and the lost‑and‑found or security office contact details (desk location, phone, email) plus stated retention period. Note the exact gate and staff names for follow‑up.
File a formal property claim with the airline and airport lost‑and‑found within 48 hours; include the seizure receipt, photographs, purchase receipt, boarding pass and serial/model details. Request a claim/reference number and a timeline for response; keep all correspondence.
If the item is declared hazardous and destroyed, request a written statement explaining the legal/regulatory basis and a destruction certificate for insurance or reimbursement purposes. If retrieval is denied, ask for an official appeal route and the contact for the national civil aviation authority.
After the incident, save all documents in a single folder (case numbers, emails, photos, receipts). For future travel, keep device specifications and any airline approvals accessible on a mobile device and carry spare items only if regulatory guidance and the airline explicitly allow them.
FAQ:
Can I bring power banks in my hand luggage when flying with Qatar Airways?
Yes. Qatar Airways permits portable chargers in carry-on bags but not in checked luggage. Small units under 100 Wh (watt-hours) are allowed without prior permission. Power banks rated between 100 Wh and 160 Wh may be carried only with airline approval and are usually limited to two per passenger. Units above 160 Wh are not permitted on passenger flights. Terminals should be protected against short circuits (for example, by keeping them in their original packaging, using terminal covers, or placing each device in a separate pouch).
How do I calculate the watt-hour (Wh) rating if my power bank lists only mAh?
Use this formula: Wh = (mAh ÷ 1000) × V. Most power banks use a nominal cell voltage around 3.6–3.7 V. For example, a 10,000 mAh bank at 3.7 V equals (10,000 ÷ 1000) × 3.7 = 37 Wh. Some manufacturers also state capacity at the USB output (5 V), which will give a different Wh value; rely on the battery cell voltage if that is available. If the label is missing or unclear, check the manufacturer’s specifications or contact customer support before travel.
Can I carry several power banks in my carry-on, and are there limits on quantity?
Carrying multiple small power banks (each under 100 Wh) for personal use is generally acceptable. For units rated 100–160 Wh, airlines typically restrict the number to two per passenger and require prior approval. All spare power banks must stay in hand luggage; they should not be packed in checked baggage. Security staff may ask you to show the labels or move devices to the cabin if they are discovered during screening.
Do I need to declare power banks or get approval from Qatar Airways before my flight?
If all your power banks are under 100 Wh, you normally do not need to request permission or make a special declaration, though security screens may still inspect them. If any unit is between 100 Wh and 160 Wh, you should contact Qatar Airways ahead of travel to request approval; approval may be granted with conditions. Devices above 160 Wh are not allowed and cannot be approved. When in doubt, contact the airline or check their official guidance before leaving for the airport to avoid delays.
What happens if security finds a power bank in my checked baggage at the airport?
If a power bank is discovered in checked luggage, airport security or airline staff will typically require it to be removed and placed in carry-on baggage. If you cannot move it to the cabin, the device may be confiscated. For items exceeding permitted ratings, staff may refuse carriage or dispose of the item. To avoid this, pack all power banks in your carry-on and ensure they are clearly labeled with capacity information.
