What is the Powerbank Ban on Aircraft?
The International Civil Aviation Organization (ICAO), a specialized United Nations agency, is considering a global ban on powerbanks aboard aircraft following a series of dangerous incidents involving lithium-ion batteries. This potential prohibition represents the most significant tightening of aviation safety regulations for portable electronic devices in decades, with the FAA reporting 22 powerbank fire incidents in 2025 alone. The proposed restrictions could fundamentally change how travelers use electronic devices during flights, potentially limiting passengers to just one laptop and one mobile phone without any external battery packs.
Why Are Powerbanks Considered Dangerous on Aircraft?
Powerbanks, also known as portable chargers, contain lithium-ion batteries that pose significant fire risks when damaged, defective, or improperly handled. Aviation expert Joris Melkert of TU Delft describes the situation as 'a headache dossier' due to the clear increase in incidents ranging from smoke development to complete aircraft fires. 'The past years have shown a clear increase in incidents with powerbanks on board, varying from smoke development to complete aircraft fires,' Melkert explains.
The Science Behind Lithium Battery Fires
Lithium-ion batteries can experience thermal runaway—a chain reaction where overheating causes more overheating—that's particularly dangerous in aircraft cabins. Unlike typical fires, lithium battery fires are chemical reactions that can't be extinguished with conventional firefighting methods. The aviation safety regulations have struggled to keep pace with the proliferation of high-capacity powerbanks, many of which exceed safe energy limits for air travel.
Recent Incidents Driving Regulatory Changes
Several high-profile incidents have accelerated the push for stricter regulations:
- Air Busan Fire (January 2025): A budget airline aircraft caught fire and burned completely due to an overheated powerbank, resulting in 27 injuries among 176 evacuated passengers and crew.
- KLM Incident: Smoke developed in the cabin during a São Paulo to Amsterdam flight from an overheated powerbank.
- FAA Statistics: The U.S. Federal Aviation Administration reported 22 cases in 2025 where powerbanks caught fire on aircraft.
These incidents highlight why the airline safety protocols are being reevaluated globally. The current rules already prohibit powerbanks in checked baggage and require them to remain within reach in the cabin, but these measures have proven insufficient to prevent dangerous situations.
Current vs. Proposed Powerbank Regulations
| Current Rules (2025) | Proposed Rules (2026) |
|---|---|
| Powerbanks allowed in cabin baggage only | Potential complete ban on all powerbanks |
| Must remain within passenger reach | Limited to 1 laptop + 1 phone maximum |
| Prohibited in checked baggage | No external battery packs permitted |
| Capacity limits: Under 100Wh generally allowed | Possible phone usage restrictions |
What Travelers Need to Know About the Timeline
The ICAO is expected to finalize new regulations during a council meeting in March 2026. These international guidelines would then need to be adopted into national and European legislation. 'That will still take some time, but not years,' Melkert notes, suggesting implementation could occur within months rather than years. Airlines like Lufthansa have already implemented their own restrictions, banning powerbank use onboard their aircraft.
Japanese Aviation Authorities' Stance
Japanese authorities are considering even stricter measures, potentially banning mobile phone use entirely during flights according to reports from The Asahi Shimbun. This reflects growing concern about all battery-powered devices in aircraft cabins and represents the most conservative approach to aviation safety currently under discussion.
Practical Implications for Air Travelers
If implemented, the powerbank ban would require travelers to:
- Plan device usage around available aircraft power outlets
- Ensure devices are fully charged before flights
- Consider purchasing airline-approved portable power solutions
- Follow specific airline regulations that may vary by carrier
The travel technology restrictions would particularly affect business travelers, digital nomads, and anyone relying on multiple electronic devices during long-haul flights. Airlines may need to upgrade in-seat power systems to accommodate increased demand for charging outlets.
Frequently Asked Questions
Why are powerbanks dangerous on airplanes?
Powerbanks contain lithium-ion batteries that can experience thermal runaway, causing fires that are difficult to extinguish in aircraft cabins. The confined space and limited firefighting resources make these incidents particularly dangerous.
When will the powerbank ban take effect?
The ICAO is expected to finalize regulations in March 2026, with implementation likely within months following national adoption processes. Some airlines like Lufthansa have already implemented restrictions.
Can I still carry a powerbank in my checked luggage?
No, powerbanks have been prohibited in checked baggage for years due to fire risks. They must be carried in cabin baggage where any incidents can be addressed immediately.
What alternatives exist if powerbanks are banned?
Travelers can use in-seat power outlets, ensure devices are fully charged before flights, or consider airline-approved portable power solutions that meet safety standards.
Will this affect other battery-powered devices?
Yes, the regulations may extend to all lithium-ion battery devices, with Japanese authorities considering restrictions on mobile phone use during flights.
