Power Bank Rules for Flights from India: Cabin, Limits and Use
Power banks are the one item that trips up almost everyone at an Indian airport, because the rule is the opposite of what people expect: they must travel in your cabin bag, and they are banned from checked luggage. Here is exactly what is allowed, the size limits that decide it, how many you can carry, and the newer rule about using one during the flight.
Short answerYes, power banks are allowed on flights from India, but only in your cabin or hand baggage, never in checked bags. A power bank up to 100 watt-hours (roughly 27,000 mAh) is fine with no approval, which covers almost every consumer power bank. Since a DGCA advisory circular dated 11 November 2025, Indian carriers tell you not to use or charge one in the air, and it must be kept within reach rather than in the overhead bin. The exact allowance differs by airline — there is a table below.
Cabin or check-in?
Cabin, always. A power bank is treated as a spare lithium battery, and spare lithium batteries are not permitted in the aircraft hold anywhere in the world, under the same international dangerous-goods rules that India's DGCA applies. The reason is safety: if a battery overheats, the crew can see and deal with it in the cabin, but not in a sealed cargo hold. So the answer to "power bank in cabin or check-in" is never check-in. If you accidentally pack one in a bag you are checking, take it out and move it to your hand baggage before you drop the bag.
The size limit that decides everything
What is allowed comes down to the power bank's capacity, measured in watt-hours (Wh). Three bands do the work. Worth being precise about where they come from: these thresholds are not in any DGCA circular. They come from the ICAO Technical Instructions and the IATA Dangerous Goods Regulations, which each airline then writes into its own conditions of carriage. That is why the bands are consistent worldwide, and also why the fine print differs from one Indian carrier to the next.
| Capacity | Watt-hours | Allowed on board? |
|---|---|---|
| Up to about 27,000 mAh | Up to 100 Wh | Yes, in the cabin, no approval needed |
| About 27,000 to 43,000 mAh | 100 to 160 Wh | Only with the airline's prior approval, usually two maximum |
| Above about 43,000 mAh | Over 160 Wh | Not allowed on passenger flights at all |
The good news is that the first band covers almost everything people actually own. The trouble only starts with the large, high-capacity packs meant for camping or professional gear.
How to check your own power bank
Most power banks print their rating in milliamp-hours (mAh) rather than watt-hours, so you may need to convert. The sum is simple: watt-hours equal the mAh divided by 1,000, multiplied by the voltage, which for these batteries is 3.7 volts. In practice:
- A 10,000 mAh power bank is about 37 Wh, well inside the limit.
- A 20,000 mAh power bank is about 74 Wh, still comfortably fine.
- A 27,000 mAh power bank is about 100 Wh, right at the no-approval line.
So a standard 10,000 or 20,000 mAh power bank, the kind most people carry, needs no permission at all. If yours does not print a Wh figure and you cannot find the mAh either, it is worth checking before you fly rather than risking it at security.
How many can you carry? It depends on the airline
This is where the generic advice on most sites falls down. "Two" is the usual answer, and it is wrong for at least one major Indian carrier. We read the three airlines' own published pages on 23 August 2026 and they do not agree with each other:
| Airline | Quantity allowed | Wh ceiling | In-flight use |
|---|---|---|---|
| IndiGo | Maximum 2 devices per passenger | 160 Wh each | "Must not be used, charged, or recharged during the flight" |
| Air India | "No more than two spare batteries per person" | 100 Wh | Cabin only; spare batteries not permitted in checked baggage |
| SpiceJet | Up to 20 spare batteries under 100 Wh; 2 in the 100–160 Wh band | 160 Wh with approval | "Use, charging, or placement in overhead bins during the flight is not permitted" |
So the honest answer to "how many power banks can I carry" is: on IndiGo, two; on Air India, two spares and nothing over 100 Wh; on SpiceJet, as many as twenty small ones, but only two in the larger band and those need approval at check-in. If you are flying more than one of them on a single itinerary, plan for the strictest.
Spare loose lithium batteries follow the same logic whichever airline you pick: they ride in the cabin, and each one should have its terminals protected — taped over or in its own pouch — so nothing can short against keys or coins. SpiceJet spells this out: articles whose primary purpose is to be a power source "must be individually protected to prevent short circuits".
Using a power bank during the flight
This is the part that changed most recently, and it catches out even seasoned flyers. The source is DGCA Dangerous Goods Advisory Circular No. 01/2025, file number DGCA-13008/37/2025-IR-DGCA, dated 11 November 2025. Indian carriers rolled it into their own conditions of carriage over the following weeks, which is why a lot of coverage dates it to early 2026 — that was the airline rollout, not the rule.
It is worth being exact about what the circular is, because it is widely mis-described. It is an advisory addressed to air operators and airport operators, not a passenger-facing statute with penalties. It directs airlines to make cabin announcements telling passengers to:
"Carry power banks and spare batteries only in hand baggage."
"Using or charging power banks is not allowed during flight."
"Immediately inform cabin crew if any device emits heat, smoke, or an unusual odor."DGCA Dangerous Goods Advisory Circular 01/2025, para (vii). Para (viii) adds that power banks and spare batteries "shall not be placed in overhead bins".
So the rule you actually meet at the gate is the airline's, adopted from that advisory. In practice it comes to the same thing: keep the power bank within reach, under the seat in front or in the seat pocket rather than the overhead bin, and do not charge from it in the air. Charge your phone before you board, or from the seat's own USB socket if it has one.
What about batteries inside your devices?
The rules above are for spare power banks and loose batteries. A battery that is installed inside a device, your phone, laptop, camera or tablet, is treated differently: those devices can travel in either cabin or checked baggage, though it is far better to keep them in the cabin so you have them with you and can act if one overheats. If you must check a device, switch it fully off, not just to sleep, and protect it from being crushed. Loose spare batteries for those devices, though, come back to the cabin-only rule.
Common questions
Is a power bank allowed in flight in India?
Yes, in your cabin or hand baggage only, never in checked luggage. Up to 100 Wh, about 27,000 mAh, needs no approval, which covers almost all consumer power banks.
Is a power bank allowed in check-in baggage?
No. Power banks and spare lithium batteries are banned from checked or hold baggage on every airline, so they must go in the cabin with you.
What is the power bank limit for a flight?
Up to 100 Wh is fine without approval. From 100 to 160 Wh you need the airline's permission and can carry at most two. Anything above 160 Wh is not allowed on passenger flights. How many you may carry in total differs by airline — see the comparison table above.
Can you use a power bank during the flight?
On Indian carriers, no. Following DGCA Advisory Circular 01/2025 of 11 November 2025, the airlines instruct you not to use or charge a power bank in the air, and to keep it within reach rather than in the overhead bin.
