Flying from Hong Kong with a power bank? Start with the airline’s carriage rules, then choose the battery capacity, weight and charging connections that suit your trip. This guide covers Hong Kong airport departures and the MOMAX models currently listed by EverythingStore.
Hong Kong power-bank flight rules in 2026
Hong Kong’s Civil Aviation Department issued DGAC 2/2026 on 28 March 2026 with immediate effect for flights departing Hong Kong International Airport: each passenger may carry no more than two power banks, in cabin baggage only. Passengers must not recharge power banks during the flight.
Before travelling, check your operating airline’s latest requirements for battery energy in watt-hours (Wh), any approval needed, onboard use and where the pack must be kept. These may be stricter than the circular. Check each flight on a connecting itinerary, including any domestic flight at your destination.
Protect the pack against short circuits and accidental activation. Keep it separate from loose metal objects and follow the manufacturer’s packing instructions. If cabin baggage is collected at the gate, tell staff that it contains a power bank and keep the power bank in the cabin.
Is 5000mAh or 10000mAh better for travel?
Choose 5000mAh when you prioritise a lighter pack for daily top-ups; compare 10000mAh when you want more nominal capacity and accept the extra size and weight. Capacity does not guarantee a number of full phone charges. Wireless transfer losses, temperature and how you use your phone all affect the result.
For flight checks, read the actual Wh marking on your pack. A headline mAh number alone does not establish airline acceptance: different battery voltages produce different energy ratings. Use the exact model’s documented Wh rather than a generic conversion using your phone’s USB charging voltage.

Magnetic attachment and wireless speed are separate
MOMAX explicitly limits compatible iPhone wireless output to 7.5W for Q.Mag X IP116A and Q.Mag X1 IP117A, even though their advertised wireless maximum is 15W for compatible devices. S.Pass IP161Q2 lists Qi2 / MPP up to 15W; S.Pass² IP163Q22 lists Qi 2.2 up to 25W. These maxima require a receiving device that supports the matching charging profile. The checked S.Pass Air specification does not identify it as Qi2.
Built-in cable or a separate cable?
Mini⁺ IP171 includes a retractable USB-C cable and up to 45W wired output. Pro⁺ IP175HK combines a battery pack, retractable cable and detachable UK wall plug; its reviewed configuration is 357g. A wall plug does not remove the battery’s carriage restrictions. Confirm USB-C PD requirements and shared-output limits for a laptop rather than choosing solely from the headline wattage.
Questions before you pack
Can a power bank go in checked baggage?
For Hong Kong departures covered by DGAC 2/2026, power banks belong in carry-on baggage only. Keep them with you if a bag is checked at the gate.
Does a listed Wh value guarantee I can take that model?
No. The actual battery label, condition, quantity and your airline’s current rules all matter. This page lists manufacturer figures and does not certify an individual pack or guarantee boarding acceptance.
Can I charge my power bank from the aircraft’s USB socket?
DGAC 2/2026 prohibits recharging power banks during flights. Check the airline separately for its rules about using a power bank to charge other devices.
Where can I check price, stock and Hong Kong delivery?
Open the exact product option linked in the table. EverythingStore currently offers free SF Express delivery to Hong Kong with no minimum spend; estimated delivery is 2–5 business days for an in-stock, paid order with a complete address. Read the delivery and returns conditions before ordering. For a capacity or compatibility decision, compare the power-bank category and Q.Mag X versus X1 guide.
