Cathay Pacific power bank rules prioritize passenger safety amid rising concerns over lithium battery risks on flights. These regulations, updated in 2025, strictly govern what power banks you can bring, where to store them, and how to use them during travel.
Cathay Pacific Power Bank Capacity Limits
Cathay Pacific allows power banks under 100Wh without approval in carry-on baggage. Devices between 100Wh and 160Wh require prior airline approval at least 48 hours before your flight, while anything over 160Wh remains prohibited entirely. Calculate watt-hours by multiplying voltage by amp-hours, using the industry standard of 3.7V for accurate compliance with Cathay Pacific lithium battery policy. Spare batteries, including power banks, must stay below 2 grams of lithium content to meet Hong Kong Civil Aviation Department standards enforced on all Cathay Pacific flights.
Strict Carry-On Storage Rules
Power banks must go in your carry-on baggage under the seat in front of you, never in checked luggage or overhead bins. This Cathay Pacific power bank storage rule prevents hidden thermal runaway risks, allowing quick crew response if issues arise. Protect terminals by taping them or using original packaging to avoid short-circuiting during your journey on Cathay Pacific international flights.

Smart bags with non-removable batteries over limits get denied, but removable ones can check if powered off.
