Recent developments in airline safety regulations have sparked discussions about the use of power banks during flights. Many airlines, particularly those based in Asia, have implemented restrictions on charging devices with portable power banks containing lithium-ion batteries. Once the aircraft reaches an altitude of 10,000 feet, passengers are generally permitted to charge their phones using the seat's built-in power ports. However, a growing number of carriers prohibit the use of external power banks throughout the journey.

Asian-based airlines such as Cathay Pacific, Singapore Airlines, and Thai Airways have taken decisive action to ban power bank usage at all stages of flight, including pre-departure. These measures stem from concerns over potential fire hazards linked to lithium-ion batteries. While travelers cannot use power banks mid-flight, they must still carry these devices in their hand luggage rather than checked baggage. Additionally, power banks need to remain switched off and stored securely under the seat in front, within the seatback pocket, or on the passenger's person. Specific guidelines may require placing the power bank in a plastic bag or covering its terminals with tape for added safety.

These stringent policies emerged following a fire incident aboard an Air Busan plane at Gimhae International Airport in South Korea. In response, regulatory bodies like Hong Kong’s Civil Aviation Department (CVD) and South Korea’s Ministry of Land, Infrastructure and Transport (MOLIT) issued bans on power bank usage across domestic carriers. The CVD emphasized its concern regarding safety breaches potentially caused by lithium batteries overheating or malfunctioning. While U.S. airlines have yet to adopt similar measures, passengers should stay informed about evolving regulations to ensure compliance and peace of mind during travel. Prioritizing safety not only protects individuals but also fosters trust in aviation practices worldwide.
