Passengers travelling through Hong Kong International Airport have been caught off guard by a newly enforced limit restricting individuals to carrying no more than two power banks, as authorities implement tighter aviation safety measures.

The rule, introduced in line with updated safety guidelines on lithium batteries, aims to reduce fire risks associated with portable charging devices.

Power banks, which contain lithium-ion batteries, have been identified as a potential hazard if damaged, improperly stored, or exposed to heat during flights.

Travellers reported confusion at security checkpoints, with some forced to discard or repack excess devices after being informed of the new restriction.

The sudden enforcement has prompted calls for clearer communication to ensure passengers are aware of the requirements before arriving at the airport.

Airport authorities have emphasised that the measure is part of a broader effort to enhance safety standards in aviation, aligning with international practices aimed at mitigating battery-related incidents.

Officials noted that the majority of passengers comply once informed, but initial adjustments have led to delays and inconvenience.

Airlines and travel operators are expected to increase outreach efforts, including pre-flight notifications and updated guidance, to help passengers prepare in advance.

The focus remains on ensuring that safety protocols are followed without disrupting travel unnecessarily.

The development highlights the growing attention on battery safety in the aviation sector, where evolving technology has introduced new challenges for regulators and operators.

As awareness improves, authorities expect smoother compliance, reinforcing the balance between passenger convenience and the imperative of maintaining rigorous safety standards.
