UK Aviation Regulator Warns Power Bank Incidents Increasing on Flights, Citing EasyJet Diversion

The UK Civil Aviation Authority (CAA) has reported a discernible increase in serious incidents stemming from portable power banks on commercial flights, urging passengers to adhere to safety regulations rigorously. The agency highlighted the inherent risks of overheating or combustion associated with these devices, particularly their lithium-ion batteries.

Flight Diversions and Safety Concerns

Jonathan Nicholson of the CAA underscored that restrictions, such as the prohibition of power banks in checked luggage, are not arbitrary. He pointed to a recent EasyJet flight, EZY2618, travelling from Hurghada, Egypt, to London Luton, which was compelled to divert to Rome Fiumicino. The diversion occurred after a passenger alerted cabin crew to a power bank stowed in the aircraft's hold, necessitating an overnight stay for passengers and a rescheduled flight.

Data from UL Standards & Engagement, a US-based safety organisation, indicates an average of two 'thermal runaway incidents' per week on flights in 2024. These incidents, involving overheating lithium-ion batteries in various rechargeable devices, saw a 15% increase between 2019 and 2024, compiled from voluntary reports by 37 airlines.

Public Awareness and Quality Concerns

A November 2025 survey of 1,000 UK passengers conducted by the CAA revealed that over a third were aware of lithium batteries and associated rules but lacked specific knowledge of the regulations. Older passengers, specifically those over 55, demonstrated greater familiarity with the guidelines.

Nicholson explained the strictness of these regulations, noting that power banks typically contain larger, more powerful batteries than other portable devices, making them prone to overheating. He emphasised the significant fire hazard they represent when ignited, despite cabin crew receiving training to manage such events. Passengers are advised to handle power banks with care, recognising that they often endure more physical damage than other personal electronic devices, and to invest in high-quality products to mitigate risks associated with cheaply manufactured alternatives.

While minor variations exist in airline policies, the overarching guidance mandates that portable chargers be kept within carry-on luggage, preferably under the seat, rather than in overhead compartments.
