SWISS and Edelweiss Ban In-Flight Use of Power Banks, Citing Safety Concerns

Effective January 15, 2026, the era of unlimited onboard power comes to an abrupt and decisive halt for passengers on SWISS and Edelweiss. In a bold move to prioritize cabin safety over convenience, both carriers have instituted a strict prohibition on the use of power banks during flight. This is not merely a suggestion; it is a hard regulation. Passengers are now strictly forbidden from charging their phones, tablets, or laptops using portable batteries once they step onto the aircraft.

The urgency of this decision underscores a critical shift in aviation safety protocols. The airlines explicitly state that charging the power bank itself via the aircraft’s USB ports or sockets is also banned. This double-lockdown on energy transfer is designed to eliminate the risk of thermal runaway at 30,000 feet. While travelers have grown accustomed to constant connectivity, this new mandate forces a dramatic behavioral change. The message from the Lufthansa Group is undeniable: safety is non-negotiable, and the risks associated with active lithium-ion charging in the air have become too great to ignore.

The crackdown extends beyond usage to possession. Passengers are now capped at carrying a maximum of two power banks, and the logistics of stowage have been rigorously redefined. Gone are the days of tossing a battery pack into the overhead bin. Under the new regime, these devices must remain strictly on the passenger’s person, in a seat pocket, or in carry-on baggage stowed beneath the seat in front. This ensures that in the event of ignition, the device is immediately accessible to the crew, rather than smoldering undetected behind closed locker doors.

Furthermore, the airlines have imposed a strict energy ceiling. Standard allowance is capped at 100 watt-hours. Any device falling between 100 and 160 watt-hours now requires explicit prior approval from the airline, creating a significant hurdle for power-hungry travelers. Devices exceeding this limit are banned entirely. These draconian measures mirror the rules for e-cigarettes, creating a unified front against lithium-based hazards. For the Swiss traveler, this means meticulous packing and a rethink of their travel tech strategy is now mandatory.

The justification for these stringent measures is written in smoke and debris. The industry is grappling with a staggering surge in lithium battery incidents, proving that the threat is not theoretical—it is lethal. The most harrowing example occurred in January 2025, when a power bank ignited aboard an Air Busan Airbus A321. While 170 passengers and crew escaped, the fire destroyed the aircraft. This was a wake-up call that prevention is the only viable strategy.

The danger lies in the physics of charging. When a power bank is in use, lithium-ion cells actively discharge energy, generating heat. If a cell is defective or damaged, this heat can trigger thermal runaway—a rapid, self-feeding fire that is notoriously difficult to extinguish. Recent history is littered with near-misses: a smoke-filled Batik Air cabin in February 2025, a mid-flight fire on an Air China A321 in October, and a burn injury on an Asiana flight in January 2026. Even in Switzerland, the risk hits home; in May 2023, an EasyJet flight out of Geneva was forced to return after an e-cigarette battery ignited. SWISS is acting to ensure they are not the next headline.

SWISS and Edelweiss are not acting in isolation; they are joining a growing coalition of safety-conscious carriers. Emirates led the charge by banning portable chargers in late 2025, while Air France, Singapore Airlines, and Qatar Airways have long prohibited their use. In contrast, budget carriers like EasyJet and Ryanair currently maintain more permissive policies, creating a fragmented regulatory landscape for European travelers. However, with the Lufthansa Group throwing its weight behind these restrictions, the industry standard is shifting rapidly.

For Swiss citizens and international residents, the implication is clear: the convenience of personal power is being sacrificed for the necessity of survival. Charging via the aircraft’s own power supply remains the only safe alternative, as it draws a lower current and generates less heat. As we move further into 2026, passengers must adapt to a new discipline: bring fewer batteries, keep them close, and do not expect to use them until you are back on the ground. The era of the 'always-on' flight is officially over.
