After the October 2025 IndiGo cabin fire, the DGCA tightened how Indians can carry and use power banks. Here is the honest 2026 picture — the Wh maths, the cabin-only rule, the in-flight charging ban and how to avoid losing your power bank at the gate.
Quick answer
On Indian flights in 2026 a power bank is treated as a spare lithium battery: it must travel in your cabin baggage only (never in checked-in luggage), it must be 100 Wh or less to be carried freely, and you may carry a maximum of two spare power banks per passenger (units of 100-160 Wh need prior airline approval; anything over 160 Wh is banned). Following a binding DGCA advisory issued 11 November 2025, in-flight use is banned — you cannot charge a device from a power bank in the air, and you cannot charge the power bank from the aircraft's USB port. Many carriers now also ask you to keep power banks in the seat pocket or under the seat in front, not in the overhead bin. To check if your power bank is legal: Wh = (mAh × 3.7) ÷ 1000, so a 20,000 mAh bank is about 74 Wh — well within the limit. Always confirm the current rule on your airline's official site, as the advisory is still being operationalised in 2026.
What changed in late 2025 — and why
The rules tightened sharply after a real incident. On 19 October 2025, a passenger's power bank caught fire in the cabin of IndiGo flight 6E 2107 (Mumbai-Istanbul). No one was seriously hurt, but the episode put the spotlight on lithium-battery fires in flight, which crew can only fight by containing the device with water and a fire-containment bag — there is no way to jettison a burning battery at altitude.
In response the Directorate General of Civil Aviation (DGCA) issued a binding safety advisory on 11 November 2025, reinforced by its Dangerous Goods advisory circular issued later in November 2025, with enforcement tightening into early 2026. The framework applies to every scheduled Indian carrier — IndiGo, Air India, Air India Express, SpiceJet, Akasa Air, Star Air and Alliance Air — and to foreign carriers operating to and from India. Reporting on the advisory appeared in Gulf News and other outlets; for the binding rule always read your airline's own dangerous-goods page.
This is not a uniquely Indian idea. Lithium-battery carriage has always been governed by the IATA Dangerous Goods Regulations and ICAO Technical Instructions, which is why spare batteries have long been a cabin-only item worldwide. What India did in 2025 was add the explicit no-in-flight-use rule and the keep-it-visible stowage requirement on top of the existing global Wh limits.

The Wh maths — how to check your own power bank in 30 seconds
Airlines and the DGCA measure battery energy in watt-hours (Wh), but power banks are sold in milliamp-hours (mAh). The conversion is the single most useful thing in this article:
Wh = (mAh × nominal voltage) ÷ 1000. Lithium cells have a nominal voltage of 3.7 V, so the practical shortcut is Wh = mAh × 3.7 ÷ 1000.
| Power bank capacity | Approx. Wh (at 3.7 V) | Status on Indian flights 2026 |
|---|---|---|
| 10,000 mAh | ~37 Wh | Allowed in cabin, no approval |
| 20,000 mAh | ~74 Wh | Allowed in cabin, no approval |
| 26,800 mAh | ~99 Wh | Allowed in cabin (just under 100 Wh) |
| 27,000+ mAh | ~100-160 Wh | Needs prior airline approval |
| Above ~43,000 mAh | Over 160 Wh | Banned |
Two cautions. First, many modern power banks are rated at the cell voltage of 3.6-3.7 V; if the label prints a Wh figure directly, use the printed Wh, not your own calculation — airlines go by the marking. Second, the popular 27,000 mAh laptop power banks sit right around the 100 Wh line and are frequently the ones questioned at security. If your bank has no readable Wh or mAh marking at all, security staff are within their rights to refuse it, because they cannot verify the rating. Buy from brands that print the Wh clearly on the casing.
Cabin only, never checked — and increasingly, never in the overhead bin
Spare lithium batteries and power banks must be carried in the cabin and are prohibited in checked baggage on Indian flights, in line with IATA Dangerous Goods Regulations. The logic is fire detection: a battery fire in the cabin can be tackled by crew within seconds, whereas a fire in the cargo hold is far harder to detect and suppress in time.
The 2025-26 advisory added a further layer that catches many travellers off guard: several Indian carriers now require power banks to be kept where they are visible and reachable — in the seat pocket or under the seat in front of you — rather than buried in the overhead bin. The reasoning is the same: if a power bank starts to swell, smoke or overheat, crew need to reach it immediately. Reporting on the new stowage expectation appears across coverage of the advisory (for example this summary). Practical takeaway: keep your power bank in your personal bag at your feet, not in the rolling cabin bag you stow up top.
Air India's published restricted-baggage page is a good reference for what counts as a dangerous good. If you are flying a foreign carrier on a route like Delhi to Dubai or Mumbai to Singapore, the cabin-only and Wh rules are effectively identical because they trace back to the same IATA/ICAO source — but the in-flight-use ban specifically applies to flights operating to and from India.
The in-flight charging ban — what you actually can't do
This is the part that is genuinely new and that surprises frequent flyers. As of the November 2025 DGCA advisory, on flights operating to and from India you may not use a power bank during the flight at all. Concretely, that means:
- You cannot connect your phone, tablet or laptop to a power bank to charge it in the air.
- You cannot charge the power bank itself from the aircraft's in-seat USB or power outlet.
- You can still charge your phone directly from the aircraft's own USB/AC outlet (that is the seat power the airline provides — it is not a power bank).
The point of the ban is to keep power banks switched off and idle during the flight, because an actively charging or discharging cell runs hotter and is more likely to enter thermal runaway. Crew are now briefed to ask passengers to stop using power banks if they spot it. Plan around it: charge everything to 100% before boarding, carry the aircraft-compatible cable for in-seat charging, and treat your phone battery as your real in-flight reserve. On a long-haul where you want the phone alive on arrival for your layover connectivity, this matters more than you'd think.
Spare batteries beyond power banks — laptops, cameras, e-cigarettes
Power banks are the headline, but the same lithium logic applies to other batteries Indians routinely fly with:
- Laptops, tablets, phones with built-in batteries: fine in the cabin, switched off or in sleep. Most can also go in checked baggage as installed batteries, but given the convenience-vs-risk trade-off, keep expensive electronics in the cabin anyway.
- Spare/loose lithium batteries (DSLR camera batteries, drone batteries, AA lithium cells): cabin only, terminals taped or in original packaging to prevent short circuits. Loose batteries in checked bags are a classic reason a bag gets pulled.
- E-cigarettes and vapes: cabin only, and using or charging them on board is prohibited. Note that vapes and e-cigarettes are separately banned for import and sale in India under the 2019 Act, so carrying them into India carries legal risk beyond the aviation rule.
- Smart luggage with non-removable batteries can be refused; if the battery is removable, take it out and carry it in the cabin.
For spare batteries between 100 Wh and 160 Wh (some pro camera and drone batteries), you are typically limited to two and must get airline approval in advance. Above 160 Wh is not accepted as passenger baggage at all. When in doubt, email the airline's dangerous-goods desk with the exact Wh printed on the battery before you fly.
How to pack so you don't lose your power bank at the gate
The most common bad outcome is not a fine — it's a security officer confiscating a power bank that has no readable rating, or a gate agent making you bin it because it was in your checked bag. Avoid both:
- Buy power banks with the Wh clearly printed on the body. Unmarked or scratched-off ratings are the number-one reason for refusal.
- Keep all power banks and spare batteries in your cabin bag from the moment you pack. Never let one slip into the suitcase you're checking in.
- Carry no more than two spare power banks. If you genuinely need more for a long trip, that is a conversation with the airline before travel, not at the X-ray belt.
- Tape the terminals of loose batteries or keep them in their retail packaging.
- Charge devices fully before boarding so the in-flight-use ban doesn't strand you with a dead phone.
- Keep the power bank at your feet, not overhead, so you comply with the visibility expectation and can reach it if it misbehaves.
If you are still shopping for flights, you can compare itineraries and cabins on FlightGPT — and if seat power matters to you (it now effectively replaces your power bank in the air), check the aircraft type, because in-seat USB/AC is far more common on wide-body long-haul than on short domestic narrow-bodies.
Frequently asked questions
Can I carry a power bank in checked-in luggage on an Indian flight?
No. Power banks are spare lithium batteries and must be carried in cabin baggage only — they are prohibited in checked-in luggage on all Indian carriers, in line with DGCA rules and IATA Dangerous Goods Regulations. If found in a checked bag, the bag can be offloaded.
What is the maximum power bank capacity allowed on flights in India?
Up to 100 Wh is allowed in the cabin without approval. 100-160 Wh power banks need prior airline approval and are usually limited to two. Anything above 160 Wh is banned. To convert mAh to Wh, use Wh = (mAh × 3.7) ÷ 1000, so a 20,000 mAh bank is about 74 Wh.
How many power banks can I carry per passenger?
A maximum of two spare power banks per passenger under the DGCA framework, in addition to batteries installed inside your devices. Units between 100 Wh and 160 Wh also require airline approval in advance.
Can I use or charge a power bank during the flight in India?
No. Following the DGCA advisory of 11 November 2025, in-flight use of power banks is banned on flights to and from India — you cannot charge a device from a power bank, nor charge the power bank from the aircraft's USB port. You can still charge devices directly from the aircraft's own seat power.
Why did India ban in-flight power bank use?
The DGCA tightened the rules after a passenger's power bank caught fire in the cabin of IndiGo flight 6E 2107 (Mumbai-Istanbul) on 19 October 2025. Keeping power banks switched off and within reach reduces the risk of a lithium-battery fire at altitude, which is difficult to fight in flight.
Where should I keep my power bank on the plane?
In the seat pocket or under the seat in front of you, not in the overhead bin. Several Indian carriers now require power banks to be kept visible and reachable so crew can act immediately if one overheats or smokes.
Is a 20000 mAh power bank allowed on Indian flights?
Yes. A 20,000 mAh power bank is about 74 Wh, which is well under the 100 Wh threshold, so it is allowed in cabin baggage without prior approval — provided the rating is clearly marked on the unit and you carry no more than two spares.
