Aviation regulator Directorate General of Civil Aviation (DGCA) has now barred passengers from using power banks to charge phones, laptops or other gadgets during flights, including through seat-mounted power outlets. DGCA in a ‘Dangerous Goods Advisory Circular’ issued in November 2025 flagged. .
Airlines have been tightening power-bank rules since a fire in South Korea in January. Incidents involving lithium batteries have also been getting more common. Flight attendants are well-trained, but more airlines are likely to clamp down on power banks. In late January, an Airbus A321 was running. .
India has now barred use of power banks to charge portable electronic devices inflight amid instances of lithium batteries catching fire mid-flight. The DGCA issued a new circular which states airlines must report all lithium battery-related incidents to the DGCA. Power banks contain lithium-ion.

Can you carry a battery on a plane?
Spare (uninstalled) lithium ion and lithium metal batteries, including power banks and cell phone battery charging cases, must be carried in carry-on baggage only. When a carry-on bag is checked at the gate or at planeside, all spare lithium batteries and power banks must be removed from the bag and kept with the passenger in the aircraft cabin.
Can you carry lithium ion batteries on a plane?
Lithium-ion batteries, such as power banks, should only be packed in carry-on baggage, according to US FAA and Transportation Security Administration (TSA) rules. In general, most airlines allow each passenger to carry a maximum of two lithium-ion power banks of 100-160 Watt-hour (Wh) into the cabin.
Can you take a power bank on a plane?
Power banks and batteries are now only allowed in hand luggage, not overhead bins. Passengers are also prohibited to charge their power banks by plugging them to in-seat power supply systems that airlines provide, the report says.
Can you recharge a power bank on a plane?
Similarly, passengers are not allowed to recharge the power bank from an aircraft’s USB outlet. Some airlines are requiring passengers to remove their power banks from bags and keep them in a seat pocket. They also advise insulating the terminals to avoid a short circuit. Why are airlines banning power banks now?
The 2007 National Energy Policy supports the diversification and increase of energy sources, mainly through renewable energy such as hydroelectricity, geothermal, solar, wind power and biofuels (as well as mineral coal and natural gas).
