Hong Kong passengers caught off guard by new airport limit of 2 power banks
New ICAO rule limits passengers to two power banks, but poor signage at HKIA leaves many unaware.
Hong Kong International Airport (HKIA) has abruptly enforced a new regulation limiting departing passengers to carrying no more than two portable power banks. The rule, announced by the Airport Authority on March 28th and effective March 29th, 2026, cites emerging aviation safety risks from lithium batteries as the reason, following guidelines from the International Civil Aviation Organization (ICAO). The sudden implementation, however, was marred by a critical lack of communication, with most passengers arriving at the airport completely unaware of the new restriction.
On the first day of enforcement, check-in areas displayed no specific notices about the two-power-bank limit, and no public announcements were made to alert travelers. The only visible notice was a single sign from the Civil Aviation Department near specific airline counters. Existing signage throughout the airport continued to display older rules, such as prohibitions on placing lithium batteries in checked luggage. This failure in passenger notification has created confusion and potential last-minute baggage issues, highlighting a significant gap between policy implementation and effective public communication at a major international hub.
- New rule limits passengers to a maximum of two power banks in carry-on luggage, citing ICAO safety regulations for lithium batteries.
- The regulation was enforced on March 29th, 2026, with minimal advance notice and almost no visible signage or airport announcements.
- The communication failure left many travelers unprepared, risking delays and confiscations at security checkpoints.
Why It Matters
Poor rollout of critical safety rules at a major airport disrupts travel and erodes passenger trust in communication systems.
