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. On Indian carriers you may no longer use or charge one in the air, and it must be kept within reach, not in the overhead bin.
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). There are three bands, and they are the same across Indian airlines because they follow the international standard.
| 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?
For the everyday sub-100 Wh power banks, airlines allow a reasonable number for personal use, though in practice most travellers carry one or two. For the larger 100 to 160 Wh units that need approval, the limit is a firm maximum of two per passenger. Spare loose lithium batteries follow the same logic: they ride in the cabin, and each one should have its terminals protected, taped over or kept in its own pouch, so nothing can short against keys or coins.
Using a power bank during the flight
This is the part that has changed recently, and it catches out even seasoned flyers. After an onboard battery fire, India's aviation regulator tightened the rules for all Indian carriers in early 2026: on domestic and international flights operated by Indian airlines, you may no longer use or charge a power bank in the air, and it must be kept within reach, under the seat in front or in the seat pocket, rather than stowed in the overhead bin. The thinking is the same as before, that a battery problem needs to be somewhere the crew can get to it quickly. So charge your phone before you board or from the seat's own USB socket if it has one, and keep the power bank packed away and switched off once you are on the plane.
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.
Can you use a power bank during the flight?
On Indian carriers, no. Since early 2026 you may not use or charge a power bank in the air, and it must be kept within reach rather than in the overhead bin.
