Singapore Airlines announced on March 12 that it will prohibit the charging of portable power banks through onboard USB ports and the use of power banks for personal devices during flights.

“The SIA Group complies with the International Air Transport Association's (IATA) Dangerous Goods Regulations regarding the carriage of power banks, which are classified as lithium batteries,” the airline said in a statement.
It also noted that power banks must be carried in cabin baggage and are not allowed in checked baggage on any of its flights. This advisory, along with the prohibition of power bank use and charging, will take effect on April 1, 2025.
“Customers may bring power banks with a capacity of up to 100Wh without special approval, while those between 100Wh and 160Wh require airline approval,” Singapore Airlines stated.
Similarly, Thai Airways released a statement on March 10 following incidents of in-flight fires on international airlines, suspected to be linked to power bank usage. The airline announced that “passengers are not allowed to use or charge power banks (spare batteries) during the entire flight.” This prohibition will take effect on March 15, 2025.
“These measures are implemented to ensure the highest level of safety for passengers and crew,” Thai Airways stated. “We kindly ask for your cooperation in adhering to these regulations and apologize for any inconvenience caused.”
