Battery-powered devices overheating more often on planes, raising alarm

Devices powered by lithium-ion batteries are overheating more often during airline flights and passengers often put them in checked bags that go into the cargo hold, where a fire might not be detected as quickly.

Overheating incidents rose 28% from 2019 to 2023, although such events remain relatively rare, UL Standards & Engagement said in a report released Monday.
