What's happened
Southwest Airlines has announced new restrictions on portable chargers, limiting passengers to one device with a capacity of 100 watt-hours. The policy, effective April 20, aims to reduce lithium battery fires, following a rise in incidents. The airline plans to add in-seat power by 2027 to lessen reliance on portable chargers.
What's behind the headline?
Southwest's new restrictions reflect a broader industry shift to mitigate the risks associated with lithium batteries on aircraft. The airline's decision to limit devices and ban storage in overhead bins aims to prevent thermal runaway, a chain reaction that causes batteries to overheat and ignite. The policy also emphasizes proactive risk management, with plans to equip all planes with in-seat power by 2027, reducing the need for external chargers. This move will likely influence other airlines to tighten their regulations, as the industry recognizes the potential for catastrophic fires. The focus on safety culture indicates a shift towards more stringent onboard safety protocols, driven by recent high-profile incidents. The policy's success depends on passenger compliance and effective communication, as most travelers remain unaware of the dangers posed by lithium batteries.
How we got here
The policy builds on previous safety measures by Southwest, which required passengers to keep portable chargers visible during use. The move responds to increasing reports of lithium battery fires on aircraft, including incidents in South Korea and the US, where fires have caused evacuations and delays. The FAA has reported a rise in lithium battery-related incidents, with 97 cases in 2025 and ongoing reports in 2026.
