"More airlines could clamp down on power banks after the Federal Aviation Administration issued a safety alert on Tuesday. It cited FAA data showing 50 lithium-battery incidents this year involving smoke, fire, or extreme heat. So, the regulator recommended that airlines review their firefighting processes and safety messaging to passengers. That includes educating travelers about the risks of lithium batteries, and ensuring that passengers and crew carry them "in locations where a potential thermal runaway is visible and accessible.""
"Lithium batteries power portable chargers, laptops, and phones. If overcharged or damaged, they can result in thermal runaway, where the temperature rapidly increases in a chain reaction. In the US, devices with lithium batteries are already banned from checked luggage - but airlines have started to implement stricter rules for carry-ons, too. Southwest Airlines announced in May that passengers would no longer be able to use portable charging devices while stored in bags or overhead bins."
