Power banks are useful travel companions, especially during long flights and airport delays. However, airlines impose strict rules on how passengers carry, store and use them because lithium-ion batteries can overheat and catch fire.
For travellers flying from India, the key point is that power banks must be carried in hand baggage and must not be used to charge other devices during the flight under current Indian aviation guidance.
Can You Charge a Power Bank During a Flight?
No. Under current Indian aviation guidance, passengers are advised not to use or charge power banks onboard. This includes charging a power bank through an aircraft seat’s USB port or power outlet.
Rules can differ between countries and airlines, so travellers taking international flights should check the requirements of their carrier before departure.
Why Are Power Banks Restricted on Flights?
Power banks contain lithium-ion batteries that can become dangerous if damaged, overheated or short-circuited. In rare cases, a battery can experience thermal runaway, a process in which its temperature rises rapidly and may lead to fire or smoke.
Such incidents are particularly concerning on aircraft, where cabin crew must respond quickly to a battery emergency.
Where Should You Pack a Power Bank?
Power banks must be carried in cabin or hand baggage, not checked-in luggage. Keeping them in the cabin allows the crew to respond more quickly if a battery overheats.
Indian aviation guidance also says power banks and spare batteries should remain within reach rather than being stored in overhead compartments. Follow your airline’s instructions on where to keep them during the journey.
How Many Power Banks Can You Carry?
Many airlines permit up to two power banks per passenger, each rated at no more than 100 watt-hours (Wh), although airline and national requirements may vary.
Batteries rated between 100Wh and 160Wh may require prior airline approval under some international rules, while larger units are generally prohibited. Always check the applicable rules before travelling, and ensure the capacity marking on your power bank is readable.
Safety Tips for Travellers
- Check your airline’s power-bank policy before leaving for the airport.
- Carry power banks only in hand baggage.
- Avoid carrying damaged, swollen or unusually hot batteries.
- Keep the device accessible and follow crew instructions.
- If a power bank emits smoke, an unusual smell or excessive heat, stop handling it and immediately alert cabin crew.
What Travellers Should Remember
Power banks remain useful for keeping devices charged before and after a flight, but onboard restrictions are designed to reduce fire risks. Charging your power bank before reaching the airport and checking your airline’s latest rules can help prevent inconvenience at security or during boarding.
When in doubt, follow the airline’s instructions and the aviation rules that apply to your journey.
