New Power Bank Rules for Air Travel: What You Need to Know

Air travel safety protocols are undergoing a significant shift following a high-profile incident involving a portable electronic device. In January 2025, a fire broke out due to a power bank in an overhead compartment on a South Korean Air Busan aircraft, highlighting the potential dangers of lithium-ion batteries in flight.

This event has triggered a swift response from the aviation industry, with major carriers taking proactive steps to mitigate risks. Germany's Lufthansa is at the forefront of this movement in Europe, spearheading new regulations designed to protect passengers and crew. The changes signal a broader industry trend toward stricter oversight of personal electronic devices carried in cabin luggage.

The aviation community was put on high alert after a South Korean Air Busan flight experienced a mid-air emergency. The event, which occurred in January 2025, involved a power bank stored in an overhead bin that unexpectedly ignited. While the situation was contained, the incident served as a stark reminder of the volatility of lithium-ion batteries when subjected to pressure or mechanical stress.

Such occurrences are rare but have the potential to escalate quickly in the confined space of an aircraft cabin. The proximity of passengers and the limited availability of fire suppression resources at altitude make these incidents particularly concerning for airline operators and safety regulators worldwide.

The specific circumstances of the fire have led to a comprehensive review of existing safety guidelines. Key areas of focus include:

• Proper storage of power banks during flight
• Temperature regulation for electronic devices
• Passenger awareness of battery safety
• Emergency response protocols for battery fires

In the wake of the incident, Lufthansa has emerged as a key player in reshaping aviation safety standards across Europe. The German carrier is implementing a series of updated regulations concerning the carriage of power banks and other lithium-powered devices in the cabin. These measures are designed to preemptively address the risks identified in the South Korean incident.

The airline's new policy emphasizes the importance of keeping portable chargers within the passenger's immediate control. This means power banks should not be stowed in overhead bins or checked luggage, where they are inaccessible and could pose a hazard if a thermal runaway event occurs.

Minimizing risks associated with lithium-ion batteries is a top priority for the aviation industry.

Lufthansa's leadership in this area sets a precedent for other European carriers. As the industry navigates the balance between passenger convenience and safety, the airline's proactive stance may influence broader regulatory changes across the continent.

Lithium-ion batteries, the power source for most modern portable chargers, are known for their high energy density. However, this same characteristic makes them susceptible to thermal runaway—a chain reaction where an increase in temperature causes a further increase in temperature, potentially leading to fire or explosion.

Factors that can trigger this reaction include physical damage, manufacturing defects, or exposure to extreme temperatures. In an aircraft cabin, where air pressure and temperature fluctuate, these risks are amplified. The confined space and limited oxygen supply in cargo holds make it even more critical to manage these devices carefully in the cabin.

Airlines are now educating passengers on the importance of using only certified, high-quality power banks. Devices that show signs of swelling, damage, or overheating should never be used or carried on board. The industry is also exploring technological solutions, such as improved battery management systems, to further enhance safety.

For frequent flyers and occasional travelers alike, these new regulations require a shift in packing habits. The primary rule is to keep all power banks and portable chargers in carry-on luggage. They should never be placed in checked baggage, where they are inaccessible and pose a greater safety risk.

Passengers are advised to check with their specific airline before traveling, as policies may vary. However, the general trend is toward stricter enforcement of existing rules and the introduction of new guidelines. Key recommendations for travelers include:

• Always pack power banks in your personal carry-on item
• Ensure your device is clearly labeled with its capacity (mAh)
• Do not use or charge your power bank while it is stowed
• Report any damaged or malfunctioning devices to the crew immediately

By following these simple steps, travelers can help ensure a safe and smooth journey for everyone on board.

The tightening of regulations surrounding power banks marks a significant step in modern aviation safety. As technology continues to evolve, so too must the protocols that govern its use in high-risk environments like aircraft. The incident on the South Korean Air Busan flight was a catalyst for change, prompting airlines to re-evaluate and strengthen their safety measures.

Travelers should expect to see continued emphasis on battery safety from carriers worldwide. Staying informed and adhering to airline guidelines is the best way to avoid inconvenience and contribute to a safer flying experience. The future of air travel will undoubtedly involve more stringent checks and greater passenger responsibility when it comes to electronic devices.
