📝 Important Notes
- •⚠️ CONDITIONAL — bring it, but you can't use it on Hong Kong airlines
- •Customs: no duty, no limit on personal power banks (Hong Kong is a free port).
- •Aviation rules — the important part:
- •Carry-on only; under 100 Wh freely, 100–160 Wh max two with airline approval, over 160 Wh forbidden
- •Since 7 April 2025, the Civil Aviation Department requires all Hong Kong-registered airlines (Cathay Pacific, HK Express, Hong Kong Airlines, Greater Bay Airlines) to ban using power banks to charge devices in flight, charging the power bank from the seat USB, and stowing it in the overhead bin — it must stay in the seat pocket or under the seat in front
- •Mainland Chinese airlines have similar bans and, since June 2025, mainland airports also refuse power banks without the 3C certification mark
- •Why: a Hong Kong Airlines fire in March 2025 and several mainland incidents.
- •Advice: Charge your phone before boarding. For onward mainland trips, make sure the power bank shows a 3C mark or it will be confiscated at Shenzhen/Guangzhou airports.
