Singapore Airlines has announced a new policy restricting the use of power banks on its flights, joining a growing number of carriers taking similar precautions.
Effective from April 1, 2025, passengers travelling with both Singapore Airlines and its low-cost subsidiary Scoot, will be prohibited from charging portable power banks via onboard USB ports or using them to charge personal devices.

The airline's decision comes amidst increasing concerns regarding the safety of lithium batteries, which are used in power banks. These batteries pose a fire risk due to the potential for "thermal runaway," a process where they can overheat and ignite. Although not banning power banks out right, Singapore Airlines has clarified that the external battery packs must be carried in cabin baggage and are strictly forbidden in checked luggage. Passengers are allowed to carry power banks up to 100Wh without prior approval, while those ranging from 100Wh to 160Wh require explicit airline authorisation.
The airline's announcement has sparked discussions about the enforcement of this policy. In response to queries about how cabin crew would monitor power bank usage, Singapore Airlines assured that its staff are "trained to remain vigilant and ensure that customers comply with in-flight safety procedures."

The Federal Aviation Administration (FAA) has long highlighted the risks associated with lithium-ion batteries, explaining that "thermal runaway can occur without warning as a result of various factors, including if the battery is damaged, overheated, exposed to water, overcharged, or improperly packed."
In recent months, Korea's Air Busan has also implemented a ban on passengers checking in power banks or storing them in overhead bins. The growing list of airlines restricting or banning power bank usage also includes Thai Airways, AirAsia, EVA Air, and China Airlines.
As safety regulations evolve, passengers are advised to check with their respective airlines for the latest policies regarding portable electronic devices and lithium batteries.
