Airline official
Power banks must travel in cabin baggage and Cathay applies a 2-unit limit. For power-bank verdicts, plan around the 2026 passenger-facing 100 Wh limit unless Cathay explicitly confirms a power-bank-specific 100-160 Wh approval path for the trip.
Power banks: plan around the 2026 passenger-facing 100 Wh limit. Generic 100-160 Wh lithium-battery approval language is not shown as a power-bank allowance unless Cathay explicitly confirms it for the trip.
“Hong Kong CAD DGAC 2/2026 states that, effective immediately for all flights departing from Hong Kong International Airport, each passenger may carry no more than two power banks, power banks must be in carry-on baggage only, and recharging power banks during flights is prohibited.”
Global source-monitor health is tracked on the compliance page; this verdict page only shows the citations actually used for this answer.
Citation freshness: The weakest source freshness is 50 days old against a 21-day airline SLA; re-check close to departure before relying on this verdict.

Common questions for this exact trip
Is this a guarantee at the airport?
No. This is an informational verdict based on published sources. Airline and security staff retain final authority.
Why can the same power bank get different answers by country or airline?
Power-bank rules combine global battery limits with country overlays, airline policies, storage rules, and recall notices.
When should I re-check this route?
Re-check close to departure, especially when the trip involves China, Thailand, Korea, a recalled model, or a battery near a capacity limit.
