Southwest Airlines will restrict passengers to carrying only one portable charger per flight starting April 20, 2026. The airline also prohibits storing chargers in overhead bins or checked luggage, requiring them to remain visible during use. This policy exceeds the International Civil Aviation Organization's recommendation of two chargers per passenger. Southwest will not aggressively enforce the rule but will inform travelers of the risks during booking and at airports.
Rising Lithium Battery Incidents
The Federal Aviation Administration reported 97 lithium battery-related incidents in 2025, a 42% increase from the previous year. Jeff Marootian, CEO of UL Standards & Engagement, noted that incidents correlate with the growing number of rechargeable devices passengers carry. Airlines are responding to concerns about overheating and fire hazards, particularly after a severe incident on an Air Busan plane in January 2025.
Global Safety Measures
Singapore Changi Airport will also implement stricter rules from April 15, 2026, allowing only two power banks per passenger. Passengers cannot charge or use power banks during flights. The Civil Aviation Authority of Singapore (CAAS) emphasizes reducing fire risks while accommodating travel needs. Airlines and airports are training staff and displaying information to ensure compliance.
