Use of Power Banks Banned on Flights: Why Can They Be Dangerous on Airplanes? The Reasons Will Surprise You

The Indian government has banned the use of power banks on flights. Passengers will no longer be able to charge their gadgets with power banks. This is because, due to several technical reasons, there is a risk of power banks catching fire on flights.

How can using a power bank on a flight be dangerous?

The use of power banks during flights is now prohibited in India. If you are traveling by air, you will no longer be able to charge your phone, smartwatch, or other gadgets with a power bank while on the flight. The Directorate General of Civil Aviation (DGCA) has taken this decision in light of several incidents of power banks catching fire during flights in various parts of the world. Let's understand why using a power bank on a flight can be dangerous.

Why do power banks catch fire on flights?

Almost all power banks available in the market use lithium-ion batteries. These power banks store a large amount of energy in a compact package. Sometimes, due to defects, physical damage, overcharging, or internal short circuits, the chemical reaction reaches a state of thermal runaway. This means that the battery heats up quickly but cannot cool down. Furthermore, factors such as changes in pressure, constant vibration, and heat in the aircraft increase the risk of fire.

Negligence in handling is also a factor

Proper handling of power banks is essential. Negligence can lead to significant damage. Many people keep power banks in tight pockets of their bags along with coins and keys, which can cause damage. Similarly, poor quality cables cannot control the voltage properly, increasing the risk of fire. Also, there is less airflow on flights, which causes more heat to be generated in the power bank, which can be dangerous at high altitudes and low pressure.

Take these precautions regarding power banks on flights

Always use BIS certified and good quality power banks.

Do not carry damaged power banks with you while traveling by air. When packing your luggage, do not place the power bank with metal objects.

If the power bank shows any warning signs, including overheating or emitting smoke, report it immediately to the flight crew.
