Power Bank in Flight: Airline Rules, Restrictions & Safety Guide

Last updated: 11 November 2026. Rules were checked on this date against Air India’s restricted-baggage page and published reports on DGCA and IndiGo policy. Always confirm your own airline’s latest conditions before you fly.

Yes, you can usually carry a power bank in flight in India, but only in your cabin baggage and within strict capacity limits. Airlines treat a power bank as a spare lithium battery, so it must stay with you in the cabin and never go into checked baggage. Recent fire incidents have also tightened the rules on where you keep it and whether you may use it on board. This guide explains the rules in plain language for Indian air travellers, including the 100 Wh and 160 Wh limits, how to convert mAh to Wh, why airline policies differ, and what to do with a damaged battery.

Rules change quickly after safety incidents, and no single policy applies to every airline. For wider packing rules, read our airport baggage rules in India guide, and keep our web check-in guide handy before you leave for the airport.

Quick Answer: Can You Carry a Power Bank in Flight in India?

• Cabin baggage only. Never pack a power bank in checked baggage.
• Up to 100 Wh: generally accepted without special approval. Air India publishes 100 Wh as its maximum.
• 100 Wh to 160 Wh: international guidance allows these only with airline approval, but airlines differ and some do not accept them at all.
• Above 160 Wh: not permitted as passenger baggage under international guidance.
• Using or charging it on board: restricted under DGCA’s advisory, as reported. Do not rely on it during the journey.
• Damaged, swollen or recalled batteries: do not take them to the airport.

Power Bank in Flight: Cabin Baggage vs Checked Baggage

A power bank is classed as a spare battery, not as a device with a battery built in. That is why the rule is the same on every Indian airline we reviewed: keep it in the cabin. Air India’s published guidance lists spare batteries as allowed in carry-on baggage and not allowed in checked baggage. IndiGo’s published policy, as quoted in news reports, also says power banks and loose lithium batteries are allowed only in hand baggage.

The reason is practical. If a lithium cell overheats, crew in the cabin can see smoke, smell burning and respond quickly. A fire in the hold is far harder to detect and fight.

Where to keep it inside the cabin

• Air India’s page says power banks and spare batteries cannot be placed in overhead bins.
• IndiGo’s policy, as reported, asks passengers to keep them within personal reach, such as under the seat, in the seat pocket or on your person.
• Protect the terminals from short circuits. Use the original packaging, a plastic bag, tape over the ports or a protective case.
• If your cabin bag is taken at the boarding gate and sent to the hold, remove the power bank first and carry it with you. Airlines advise this, and it is the most common avoidable mistake.

Watt-Hour Limits for a Power Bank in Flight: 100 Wh, 160 Wh and Above

Regulators measure battery size in watt-hours (Wh), not milliamp-hours (mAh). The thresholds below follow international dangerous-goods guidance, as published by aviation regulators such as Switzerland’s FOCA and Australia’s CASA. Airlines may be stricter, and Indian airlines often are.

Battery size	International guidance	What to do in India
Up to 100 Wh	Allowed in cabin baggage without airline approval	Covers most phone power banks. Air India lists 100 Wh as its maximum.
100 Wh to 160 Wh	Allowed only with airline approval, usually a maximum of two	Air India’s published limit is 100 Wh. IndiGo’s reported policy allows this range only for portable medical devices, with approval. Do not assume it will be accepted.
Above 160 Wh	Not allowed in passenger baggage	Do not carry it. Large power stations and portable generators are also not allowed.

How to Calculate Wh From mAh for a Power Bank in Flight

If your power bank shows only mAh, use this formula:

Wh = (mAh × voltage) ÷ 1000

Most power banks use lithium-ion cells rated at about 3.7 V, so a quick estimate is mAh × 3.7 ÷ 1000.

Rated capacity	Approx. watt-hours (at 3.7 V)	Likely status
5,000 mAh	18.5 Wh	Within the 100 Wh limit
10,000 mAh	37 Wh	Within the 100 Wh limit
20,000 mAh	74 Wh	Within the 100 Wh limit
26,800 mAh	about 99 Wh	Very close to the limit; check the label
30,000 mAh	111 Wh	Needs airline approval, and may be refused
43,000 mAh	about 159 Wh	Near the 160 Wh ceiling; approval needed
50,000 mAh	185 Wh	Above 160 Wh; not allowed

If the casing prints a Wh figure, use that number. It is the one that security staff read. A power bank with no readable capacity label may be refused at the checkpoint, so avoid unmarked or unbranded units.

Power Bank in Flight: Airline Approval and Latest Policies

Indian airlines do not all publish identical rules, and the table below shows why. These are summaries, not substitutes for the airline’s own page.

Point	Air India (published page)	IndiGo (published policy, as reported)
Where it must travel	Cabin baggage; not in checked baggage	Hand baggage only
Capacity	Spare batteries up to 100 Wh	Up to 100 Wh; 100 to 160 Wh only for portable medical devices, with approval
Number allowed	Maximum two spare batteries per person	Up to two spare lithium-ion batteries
Overhead bins	Not allowed	Keep within reach; not in overhead compartments
Use on board	Page states a ban for Singapore departures; confirm for your route	Must not be used to recharge devices

The operating airline’s rule applies, not the one that sold you the ticket. On codeshare flights and connecting journeys, check the policy of every airline and every airport on your route. Foreign regulators are also tightening rules: Singapore’s aviation authority announced limits of two power banks per person on flights departing Singapore from 15 April 2026, citing an addendum to the ICAO technical instructions, and it says power banks must not be charged on board.

If you think your power bank is between 100 Wh and 160 Wh, contact the airline before the trip and ask for approval in writing. Carry the confirmation with you, and be ready for the airline to say no.

Using and Charging a Power Bank in Flight

Many travellers assume that carrying a power bank means they can use it on the aircraft. That is no longer a safe assumption in India. According to media reports on DGCA’s Dangerous Goods Advisory Circular, power banks must be carried in hand baggage, must not be stored in overhead bins, and passengers must not use them to charge devices or charge them from in-seat power sockets during the flight. Reports date these restrictions to early 2026. We could not read the circular itself while writing this guide, so check DGCA’s website for the current text.

• Fully charge your phone, earbuds and power bank before you reach the airport.
• Do not plug a power bank into the seat’s USB port to charge it.
• Tell the cabin crew at once if a battery feels hot, smells unusual or produces smoke.
• Follow crew instructions even if a different airline allowed you to do something else earlier.

Damaged, Swollen or Recalled Power Banks

International lithium-battery guidance treats batteries that are damaged, defective or recalled by the manufacturer as forbidden for carriage by air. A swollen battery is already failing, so do not test whether it still works at the airport.

Warning signs

• A bulging or swollen case, or a casing that no longer closes properly
• Cracks, dents or exposed cells after a drop
• Leaking fluid, discolouration or a sharp chemical smell
• Becoming very hot while charging or when idle
• A manufacturer or government recall notice for your model

Stop using a damaged unit, do not puncture or squeeze it, and take it to an authorised e-waste collection point or the manufacturer’s service centre. Replace it before your trip instead of hoping it will pass screening.

The MOBIKINS MK-PB-04 ban

Air India’s restricted-baggage page states that DGCA has prohibited the MOBIKINS MK-PB-04 power bank from being carried in cabin or checked baggage on any flight to, from or within India because of fire-safety risks. The ban applies to this model only; it is not a ban on all power banks. Check the model number printed on yours before packing.

Power Bank in Flight: Practical Examples

• A 10,000 mAh power bank for a weekend trip: about 37 Wh. Keep it in your cabin bag with the ports covered.
• A 20,000 mAh power bank for a long journey: about 74 Wh. It is within the 100 Wh limit, but still stays in the cabin and unused during the flight.
• A 30,000 mAh unit: about 111 Wh. It sits above the limit that Air India publishes, so it may be refused. Choose a smaller power bank, or get written approval first.
• Your cabin bag is gate-checked: take out the power bank and spare batteries before you hand the bag over.
• A power bank swollen after a monsoon trek: do not travel with it. Replace it and recycle the old one.

Packing Checklist for Flying With a Power Bank

• Check the capacity label and calculate Wh if only mAh is shown.
• Confirm that the unit is not the banned MOBIKINS MK-PB-04 model.
• Check your operating airline’s current policy, including the number of units allowed.
• Pack it in your cabin bag, never in checked baggage.
• Cover the terminals with tape, a pouch or the original packaging.
• Keep it within reach, not in the overhead bin.
• Charge the power bank and your devices before the flight.
• Leave damaged, swollen or recalled batteries at home.

Frequently Asked Questions

Can I carry a power bank in flight in India?

Yes, in cabin baggage only and within the capacity limit set by your airline. Up to 100 Wh is generally accepted. Larger units need airline approval, and some airlines will not accept them.

Can I put a power bank in checked baggage?

No. Power banks and spare lithium batteries must travel in the cabin, with their terminals protected.

How many power banks can I carry?

It depends on the airline. Air India’s page allows a maximum of two spare batteries per person, and IndiGo’s reported policy also refers to two. The ICAO addendum described by Singapore’s authority also uses two. Confirm the exact limit for your carrier.

Can I use or charge my power bank during the flight?

You should not. Media reports on DGCA’s advisory say in-flight use and charging from seat power are not permitted, and IndiGo’s reported policy says the power bank must not be used to recharge devices. Charge everything before boarding.

Is a 20,000 mAh power bank allowed on a flight?

Usually yes. At about 3.7 V it equals roughly 74 Wh, which is under the 100 Wh limit. Keep it in your cabin bag and check your airline’s current policy.

What if my power bank has no Wh label?

Calculate it with the formula above and carry the product box or specification if you have it. Without a readable rating, security staff may refuse the unit, so choose labelled power banks from known brands.
