Capacity math for this model

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.
