A power bank catching fire aboard an IndiGo flight has once again highlighted a growing safety challenge for airlines: how to manage the risks posed by lithium batteries carried by passengers.
On October 11, 2026, IndiGo flight 6E 6115, operating from Delhi to Chennai, was diverted to Hyderabad after smoke was detected from a passenger’s electronic device. The power bank reportedly caught fire inside an overhead luggage compartment, prompting the cabin crew to intervene and the pilots to divert the aircraft as a precaution.
The aircraft landed safely at Rajiv Gandhi International Airport in Hyderabad, and no injuries were reported. IndiGo arranged an alternative aircraft to continue the journey to Chennai. <Cite refs={[“turn460381search1″,”turn460381search11”]}/>
While the immediate incident was brought under control, the event has renewed concerns about battery safety, compliance with onboard regulations and the effectiveness of existing safeguards.
What Happened Aboard IndiGo Flight 6E 6115?
The Delhi to Chennai service encountered an onboard fire involving a passenger’s power bank during the flight.
According to published reports, the device was stored in an overhead luggage compartment. Smoke and flames prompted an immediate cabin response, with crew members taking action to control the situation.
The pilots subsequently diverted the aircraft to Hyderabad, where it landed safely.
Although the crew successfully managed the emergency, a lithium battery fire inside an aircraft cabin presents a serious challenge. Smoke can affect visibility and passenger comfort, while a battery that continues to overheat can reignite even after the visible flames have been extinguished.
The incident also raises an important question: if passengers are expected to keep power banks accessible during a flight, how effectively are those requirements being followed?
Why Are Lithium Battery Fires So Dangerous on Aircraft?
Power banks generally contain lithium ion or lithium polymer batteries. These batteries store considerable energy in a compact form, making them useful for charging mobile phones and other portable electronics.
However, under certain conditions, a battery can overheat or suffer an internal short circuit. Physical damage, manufacturing defects and other battery failures can trigger a process known as thermal runaway.
During thermal runaway, the battery generates heat faster than it can dissipate it. The resulting reaction can release flammable gases, produce intense heat and cause flames or smoke.
One of the most difficult aspects of such incidents is that extinguishing the initial flames does not necessarily stop the underlying battery reaction. The battery can heat up again and reignite.
Inside an aircraft, this creates additional complications. The cabin is a confined environment, passengers are seated close together, and crew members must respond while maintaining overall cabin safety.
For this reason, airlines have specific procedures for managing overheating electronic devices and lithium battery fires.
What Are India’s Rules for Carrying Power Banks?
India’s aviation safety framework places restrictions on how passengers carry and use portable batteries.
Under applicable guidance and airline policies, power banks and spare lithium batteries must be carried in cabin baggage rather than checked baggage. Passengers are also required to keep them accessible instead of placing them in overhead compartments.
The Directorate General of Civil Aviation (DGCA) issued an advisory in November 2025 prohibiting passengers from using power banks to charge electronic devices during flights, including through aircraft power outlets.
These requirements are intended to reduce the likelihood of battery incidents going undetected and to make it easier for cabin crew to respond if a device begins smoking or overheating. <Cite refs={[“turn460381search0″,”turn460381search8”]}/>
The reasoning behind the overhead compartment restriction is straightforward. A battery stored directly above passengers may begin smoking or burning without being immediately noticed. If the device is kept within reach, passengers and crew have a better chance of detecting warning signs early.
However, regulations are effective only when passengers understand and follow them consistently.
DGCA Restricts a Specific Power Bank Model
The incident has also been followed by a significant regulatory development.
On October 14, 2026, reports confirmed that the DGCA had directed airlines to prevent passengers from carrying the MOBIKINS MK-PB-04 power bank on flights to, from and within India, citing safety concerns. The restriction applies to the specified model and does not represent a blanket ban on all power banks. <Cite refs={[“turn460381search2″,”turn460381search6”]}/>
The model-specific restriction adds another dimension to the wider discussion about portable battery safety.
It raises questions about product quality, battery certification, traceability and how potentially unsafe devices are identified before they enter aircraft cabins.
Consumers should check that portable battery products meet applicable Indian standards and carry the required certification where applicable. They should also avoid damaged, swollen or suspiciously cheap products from unverified sellers.
At the same time, a model-specific restriction should not be interpreted as proof that every device of the same general category is unsafe. The regulatory action concerns the identified model, while broader battery safety depends on product quality, condition and proper handling.
The Bigger Problem Is Not Just the Battery
The IndiGo incident illustrates why aviation safety cannot rely on a single precaution.
Manufacturers must produce reliable batteries. Sellers must provide compliant products. Passengers must follow airline instructions, and airlines must communicate those instructions clearly while ensuring that cabin crews are equipped to respond to emergencies.
Each part of this chain matters.
Even a high-quality battery can become dangerous if it is physically damaged or improperly handled. Conversely, a passenger may follow the storage rules and still encounter a battery malfunction.
This means that better passenger awareness must go hand in hand with product quality controls, regulatory oversight and effective emergency procedures.
Airlines may also need to examine how consistently power bank restrictions are communicated during booking, check-in, boarding and onboard announcements.
The aim should be to prevent incidents wherever possible while ensuring that any developing battery emergency is detected and managed quickly.
What Can Passengers Do to Reduce Battery Risks?
Passengers can take several practical steps before boarding a flight.
1. Keep power banks accessible. Carry them in permitted cabin baggage and follow the airline’s instructions on storage. Do not place them in overhead compartments where prohibited.
2. Never use a power bank to charge devices during a flight when airline or regulatory rules prohibit it. Follow crew instructions throughout the journey.
3. Inspect batteries before travelling. Do not carry power banks that are swollen, cracked, leaking, unusually hot or visibly damaged.
4. Buy compliant products. Check the manufacturer’s information, applicable safety certification and airline restrictions before travelling.
5. Report warning signs immediately. If a device becomes unusually hot, emits an unusual smell, begins swelling or produces smoke, alert cabin crew immediately. Do not attempt to conceal or independently handle a suspected battery emergency.
These precautions cannot eliminate every possible failure, but they can reduce avoidable risks and help cabin crews respond sooner.
Could More Restrictions Follow?
The latest incident and the restriction on the MOBIKINS MK-PB-04 model may encourage further scrutiny of portable battery safety in Indian aviation.
Possible areas of attention include stronger passenger communication, better product traceability, improved compliance checks and continued evaluation of battery-related emergency procedures.
However, any additional restrictions would need to be supported by regulatory assessments and the relevant safety evidence. A single incident should not automatically be treated as proof that all power banks present an unacceptable risk.
The wider objective is to establish a practical balance between passenger convenience and the need to protect aircraft, passengers and crew.
Portable batteries are widely used, and their presence in aircraft cabins is likely to remain an operational consideration for airlines around the world.
Conclusion: A Small Device With Serious Aviation Implications
The fire aboard IndiGo flight 6E 6115 ended without reported injuries, but it serves as a reminder that a compact consumer electronic device can create a major operational challenge when something goes wrong.
The diversion to Hyderabad, the cabin crew’s response and the subsequent restriction on a specific power bank model highlight the importance of preventive measures at every stage, from manufacturing and purchasing to storage and onboard handling.
For the aviation industry, the priority is not simply to react to battery fires after they occur. It is to reduce the chances of such incidents, improve early detection and ensure that crews can respond effectively when prevention fails.
As portable electronics continue to be part of everyday travel, battery safety will remain an important responsibility shared by regulators, manufacturers, airlines and passengers.
