Mobile Battery Ban: New Flight Restrictions for Travelers

Global air travel is facing a new set of restrictions regarding portable batteries, impacting millions of passengers who rely on power banks and other lithium-ion battery-powered devices. Several nations and airlines are tightening regulations, moving towards a near-total ban on the use of these devices during flights and limiting the quantity permitted in carry-on luggage. The changes, prompted by a series of onboard incidents involving overheating and even fires, are set to significantly alter how travelers power their devices in the air.

Japan Leads the Way with Stricter Rules

The initial impetus for these changes stems from Japan, where the Ministry of Land, Infrastructure, Transport and Tourism is preparing to effectively prohibit the use of portable batteries on aircraft. Multiple media outlets report that the new policy, expected to be implemented in April 2026, will ban charging electronic devices with power banks and prohibit charging the power banks themselves via in-flight power outlets. This move follows a series of incidents where batteries have overheated or caught fire mid-flight.

Carry-On Restrictions Expanding

Beyond usage restrictions, Japan is also considering limiting the number of power banks passengers can bring onboard. Currently, batteries exceeding 160Wh are prohibited, and those between 100Wh and 160Wh are limited to two per passenger. However, batteries under 100Wh, which previously had no quantity restrictions, are now being considered for a limit of two units per passenger. This tightening of carry-on rules reflects a growing concern about the potential fire risk posed by lithium-ion batteries, even those considered smaller, and safer.

Global Trend: Airlines Respond to Safety Concerns

Japan’s actions are not isolated. Airlines across Asia have already begun tightening their policies, and the trend appears to be spreading globally. South Korea implemented nationwide restrictions in March 2025, banning passengers from storing power banks and e-cigarettes in overhead cabins. These items must now be kept in seat pockets or under the seat. South Korean regulations also prohibit in-flight charging of power banks using aircraft USB ports. This follows an incident in January 2025 where a fire broke out on an Air Busan flight due to a power bank, with investigators finding “multiple electrical melting marks” from the device.

The Lithium-Ion Battery Risk

The increasing scrutiny of lithium-ion batteries stems from their inherent risks. While offering advantages like fast charging and extended battery life, these batteries can, in rare instances, experience thermal runaway, leading to fires or explosions. This risk is amplified in the confined space of an aircraft cabin. The US Federal Aviation Administration (FAA) has recorded over 500 in-flight lithium battery incidents involving smoke, fire, or extreme heat in the past two decades, highlighting the growing concern.

Impact on Travelers and the Portable Power Industry

These new regulations will undoubtedly impact travelers, particularly those on long-haul flights who rely on power banks to keep their devices charged. The availability of charging stations in airports remains limited, as noted by Zhang, who highlighted the essential role power banks play for business travelers and those seeking in-flight entertainment. The restrictions will force passengers to plan more carefully and potentially limit their ability to stay connected during flights.

The changes also pose a challenge to the portable power bank industry. Manufacturers will need to address safety concerns and potentially innovate to develop batteries with reduced fire risk. The restrictions on wattage and quantity could also impact sales, particularly for larger-capacity power banks popular with frequent travelers. Anker, a prominent manufacturer of portable chargers, has acknowledged the changing rules and is likely to adapt its product offerings accordingly.

Airline Discretion and the Need for Clarity

The rules surrounding lithium-ion batteries on airplanes are complex and vary significantly between carriers. While a global ban on checking these batteries in baggage is already in place, regulations regarding carry-on allowances and in-flight usage differ. This inconsistency creates confusion for passengers, emphasizing the importance of checking with individual airlines before traveling. Failure to do so could result in devices being confiscated at the boarding gate.

Looking Ahead: A Focus on Battery Safety

The tightening of regulations surrounding portable batteries reflects a broader focus on aviation safety. As lithium-ion battery technology becomes increasingly prevalent in consumer electronics, airlines and regulatory bodies are prioritizing passenger safety. The industry is likely to see continued scrutiny of battery technology and further adjustments to regulations as new incidents occur and safety standards evolve. Passengers should expect increased vigilance regarding these devices and a greater emphasis on responsible battery usage during air travel.
