India's Directorate General of Civil Aviation (DGCA) has banned the use of power banks for charging devices during flights, including through seat outlets, due to safety concerns over lithium batteries. Citing global incidents of overheating and fires, the DGCA mandates that power banks and spare batteries must be in hand luggage, not overhead bins. This aims to prevent intense, self-sustaining lithium battery fires that are difficult to detect and extinguish in confined aircraft cabins.
