Singapore implemented new aviation safety rules on April 15, 2026, limiting passengers at Changi Airport to two power banks per person after global concerns over lithium battery fires in aircraft cabins.
But this is more than a routine policy update. The move signals a global shift in aviation safety standards, as regulators respond to a rising number of battery related incidents that are difficult to contain mid flight.
What makes the change significant is how quickly it is being enforced. On its first day, security screened 275 flights and confiscated 15 excess devices, highlighting both the scale of the rollout and the number of travelers still unaware of the new limits.
And the rules go beyond simple quantity. Passengers must now comply with strict in flight restrictions, including a ban on charging power banks and guidance to keep them within reach at all times.
Why aviation authorities are tightening control on batteries
The policy stems from a growing safety concern: lithium-ion batteries can ignite under stress, especially during charging. Fires can exceed 1,000°C and produce toxic smoke, making them extremely dangerous in a pressurized cabin.
But the real shift came after several high profile incidents in 2025, including fires inside overhead lockers. These enclosed spaces delayed detection, allowing flames to spread before crews could respond.
As a result, regulators have moved away from capacity based rules toward a strict
quantity limit, reducing the total number of batteries onboard rather than just their size.
This shift has changed how passengers must manage their devices. Power banks up to 100Wh remain allowed (maximum two units), while larger units between 100Wh and 160Wh require airline approval, and anything above that is banned entirely.
However, what makes enforcement stricter is verification. Devices must have clearly visible labels showing capacity, or they risk being confiscated even if they are within legal limits.
Why everyday passenger habits must now change
That raises a second issue: behavior inside the cabin. Airlines such as Singapore Airlines and Scoot have moved to restrict not only charging but also using power banks during flights, citing heat generation risks.
Even discharging a battery to charge a phone can create thermal stress, particularly in crowded cabins. This has led to a practical ban on usage, pushing passengers to rely on in seat power instead.
And storage rules are just as critical. Power banks must be kept in seat pockets or under seats, ensuring immediate visibility and quick access if overheating occurs.
These rules reflect a broader safety philosophy. Quick detection and rapid response are now prioritized over convenience, especially after past incidents showed how quickly a hidden fire can escalate.
This is why overhead storage is no longer acceptable. A device placed out of sight could delay response time, increasing risk for everyone onboard.
Inside Changi’s strict first day enforcement
On the ground, enforcement has been notably firm. Most confiscations on April 15 involved passengers carrying three or more small devices or using power banks with faded or missing labels.
Security teams are also conducting secondary gate checks, particularly for transit passengers who may have cleared different standards at their departure airports.
This creates a new layer of compliance. Even if a device is accepted elsewhere, it may still be flagged at Changi under its stricter verification rules.
For travelers, the implications are immediate. Passengers are advised to carry power banks in clear, accessible pouches, ensure labels are legible, and limit devices to two regardless of size.
Some are even taking extra precautions, such as preserving labels with tape or carrying proof of specifications, though physical labeling remains the primary requirement.
What makes this moment significant is not just the rule itself, but what it represents. As air travel becomes increasingly dependent on personal electronics, battery safety is emerging as a frontline aviation issue.
And with Changi setting a strict precedent, similar measures could soon become standard worldwide reshaping how millions of passengers travel with their devices.
