Power Bank, Big Danger: Why a Pocket Charger Can Trigger a Flight Emergency
An IndiGo diversion to Hyderabad is the latest warning. From cabin fires in India to an aircraft destroyed in South Korea, battery incidents have prompted tighter rules. What goes wrong, and what should passengers do?
A passenger on an IndiGo Delhi–Chennai service diverted to Hyderabad after a power bank reportedly caught fire. Crews contained the incident and the aircraft landed safely, with passengers evacuated as a precaution. The airline said it was arranging onward travel for those on board.
The event adds to a series of similar fires and smoke scares involving portable chargers that can trigger flight emergencies or evacuations. In this case, smoke from the device prompted an onboard emergency response and a diversion to Rajiv Gandhi International Airport.
Indian incidents prior to this have shown the danger can appear at different stages of a journey, including a taxiing event and an evacuation after landing. In one case, a power bank was reported in a seat-back pocket; in another, evacuation slides were used and several injuries occurred during the process.
International cases cited include fires or smoke in overhead compartments affecting Hong Kong-bound or Singapore-bound flights, with crews extinguishing flames and flights landing safely. The compilation of incidents illustrates a range of outcomes from controlled incidents to evacuations and aircraft damage.
Authorities note lithium-ion cells can undergo thermal runaway, triggering heat, smoke and fire that may affect neighboring cells. Regulations and guidance are evolving, with changes in international rules aiming to limit power-bank quantities onboard and restrict recharging during flight. Passengers are urged to report warning signs promptly to crew.
