Southwest Airlines Mandates Visible Portable Chargers for Flight Safety

Starting May 28, 2025, Southwest Airlines will enforce a new safety regulation requiring all passengers to keep their portable device chargers visible and out in the open during flights. This policy mandates that power banks, phone battery cases, and other portable charging devices cannot be used from within overhead bins or inside bags stowed under seats while actively charging devices. The airline’s primary goal is to minimize the risk of onboard fires caused by lithium-ion batteries, which have been a growing concern in the aviation industry worldwide.

Why such a focus on portable chargers? Lithium-ion batteries, commonly used in smartphones, laptops, and power banks, can pose fire hazards if damaged or improperly handled. Incidents involving these batteries have increased aboard flights, prompting airlines and regulators to tighten safety protocols. Southwest’s policy aligns with similar measures already adopted by airlines like Singapore Airlines, Thai Airways, and Korean Air, which have banned or restricted the use of portable chargers in certain baggage compartments.

Passengers may still carry portable chargers in their carry-on baggage, but only if the chargers are not connected or in active use. When charging devices during the flight, the charger must remain visible at all times to allow flight crews to monitor for any overheating or smoke. This proactive visibility measure helps cabin crews quickly identify and respond to battery malfunctions, reducing the risk of in-flight emergencies.

Statistics reveal that the average U.S. passenger brings about four rechargeable devices onboard, including smartphones (82%), laptops (41%), wireless headphones (39%), and tablets (36%). Power banks accounted for 16% of all lithium-ion battery incidents reported on flights in 2023, with vaping devices causing the highest number at 35%. Such data underscores the necessity of stringent safety practices around portable charging devices during air travel.

The FAA has provided comprehensive training to flight crews on recognizing and managing lithium battery fires. Passengers are urged to immediately inform crew members if they notice any signs of overheating, smoke, or unusual behavior from their devices or batteries. This collaboration between passengers and crew is critical to maintaining onboard safety.

Implications for Travelers and Airlines

For travelers, this policy means adapting habits to ensure chargers remain accessible and visible during the entire flight. It emphasizes safety over convenience, reminding passengers that the hidden danger of lithium-ion batteries requires vigilance. Airlines benefit from reduced risk of fire-related incidents, potentially lowering emergency diversions and enhancing passenger confidence in air travel safety.

As more airlines worldwide monitor and regulate the use of portable chargers, industry standards may evolve toward stricter global safety mandates. Southwest Airlines’ initiative could signal a trend toward more transparent device usage policies in cabins, prioritizing passenger safety and regulatory compliance.

Safety Tips for Air Travelers Using Portable Chargers

• Always keep portable chargers visible while charging devices on flights.
• Do not charge devices stored inside bags or overhead compartments.
• If your device or charger shows signs of overheating or smoke, alert the flight crew immediately.
• Follow airline and TSA guidelines for carrying batteries and chargers in carry-on luggage only.

Southwest Airlines’ new policy highlights a proactive approach to passenger safety amid growing concerns about lithium-ion battery risks. By requiring visible use of portable chargers, the airline aims to reduce fire hazards and ensure rapid crew response if incidents occur. Travelers should prepare to adjust their in-flight device usage accordingly and prioritize safety over convenience.
