INIU Carry Smallest Power Bank 20000mAh 22.5W

Canonical fields

Capacity

20,000 mAh / 72 Wh (estimated)

Flight carry-on eligibility

Carry-on OK

100 Wh or less: allowed in carry-on baggage without airline approval, under the global ICAO/IATA watt-hour rule. Based on an estimated Wh figure, not a manufacturer-stated one.

Power banks must always go in carry-on baggage, never checked, regardless of capacity. Since March 2026: max 2 power banks per passenger, and recharging one during a flight is prohibited, worldwide. Some countries go further still -- South Korea bans in-flight use entirely; China requires a 3C-certified power bank at any Chinese airport or domestic flight (not something this data can check). Always confirm with your specific airline and destination before travel.
