Southwest Airlines will require passengers to keep power banks and portable chargers visible during flights starting May 28, citing safety concerns over lithium-ion battery fires.

Devices can no longer be used while stored in bags or overhead bins.

The airline is the first U.S. carrier to adopt such a policy, joining some international airlines like those in South Korea, ABC News has reported.

The move follows a rise in battery-related fire incidents on planes, with 19 cases reported by the FAA this year.
