Passengers departing from Hong Kong and Macao airports are now limited to carrying a maximum of two power banks on flights, following updated aviation safety guidance issued by the International Civil Aviation Organization.
The new specifications, which took effect on 27 March 2026, also prohibit passengers from using or recharging power banks during flights. The changes are aimed at addressing safety risks linked to lithium battery-powered devices carried on aircraft.
At Hong Kong International Airport, Hong Kong’s Civil Aviation Department said airlines have been notified to enforce the updated requirements, allowing each passenger to bring no more than two power banks on departing flights.

Authorities said the rule aligns with the latest international safety standards governing the transport of lithium battery devices by air.
The same restrictions have been implemented at Macau International Airport. The Civil Aviation Authority of Macao said passengers may carry no more than two power banks in their carry-on baggage and are not allowed to charge them during flights.
While the restrictions apply to passengers, flight crew members may continue to carry and use power banks when required for aircraft operations, according to ICAO guidance.
