Current Regulations & Airline Policies
Global aviation standards (like IATA and FAA) mandate that spare lithium-ion batteries and power banks must only be carried in carry-on baggage, never in checked luggage—this ensures fires are quickly noticed and addressed .
Capacity limits: up to 100 Wh is generally allowed. Between 100–160 Wh requires airline approval. Anything above 160 Wh is prohibited (unless for mobility aids) .
Stricter airline-level restrictions are rapidly emerging:
Since March 2025, South Korea banned storing power banks in overhead bins and capped to 5 units per person; use during the flight is also disallowed .
Asian carriers like Singapore Airlines, Scoot, China Airlines, Thai Airways, AirAsia, EVA Air, and Cathay Pacific now prohibit in-flight use or charging .
Southwest Airlines (U.S.) as of May 28, 2025, requires power banks to be kept visible and out of bags while in use—reflecting 19 battery-related incidents already in 2025, vs. 89 in 2024 .
Emirates will, starting October 1, 2025, allow only one power bank (≤100 Wh), which must be stored under the seat or in the seat pocket—no charging or use permitted during flight .
In China, as of June 28, 2025, power banks without proper 3C certification or those recalled are banned from flights .
Risks & Incident Statistics
Incidents are rare but increasing:
A January 28, 2025 fire on Air Busan Flight 391 was traced to a power bank in an overhead bin—a ground fire caused injuries to seven people and total aircraft loss .
The FAA logged 89 battery-related incidents in 2024, and already 19 in early 2025, with portable chargers responsible for around 19%—second only to e-cigarettes (28%) .
Other incidents include overheating power banks, one diverted flight due to a charger, a Virgin Australia flight fire in an overhead locker, and a Spirit Airlines diversion in 2023—all linked to battery issues .
Why power banks are risky:
Lower-cost models often lack robust safety circuitry and can be prone to damage or defects, increasing risk of thermal runaway (sudden, uncontrollable heating leading to fire) .
In a compact aircraft cabin, lithium battery fires are especially dangerous—they emit toxic gases and are hard to extinguish with water .
Should We Ban Power Banks Entirely?
Arguments for a total ban:
- Simplifies enforcement: No confusing rules, fewer small-scale incidents.
- Zero chance of malfunction mid-air; total mitigation.
- Arguments against a full ban:
- Power banks are essential for many passengers, particularly on long-haul or connecting flights.
- The relative risk remains low compared to the number of flights and usage—most incidents are caught early when carried in the cabin.
- Effective safety frameworks (size limits, carry-on only, visibility, certification) keep risks manageable without blanket prohibition.
Keeping Flights Safe—and Practical
- Stick to carry-on baggage, never checked, and protect terminals (e.g., tape, sleeves) .
- Stay under 100 Wh (or get approval for up to 160 Wh). Do not bring over-capacity units .
- Keep power banks visible and accessible during use—if overheating occurs, quick action saves lives .
- Choose certified and reputable products, especially ones with safety marks like 3C (China) .
- Follow your airline’s specific rules, because compliance varies by carrier and region .
- Educate passengers—awareness of battery risks, safe handling, and rules is crucial .
Final Thought
Power banks remain a practical and manageable risk—not a reason for outright bans in most cases. By combining sound regulation, better-quality products, visible usage, and passenger awareness, we can minimize hazards while keeping modern travel convenient and safe.
