2026 power bank flight rules

Short answer: In 2026, the safest public rule is: carry no more than two lithium-ion power banks, keep each at 100 Wh or less unless your airline explicitly permits otherwise, carry them in cabin baggage only, do not recharge a power bank from the aircraft power supply, and follow crew instructions on in-flight use and storage.
ICAO introduced a Technical Instructions addendum on March 27, 2026 that separates power banks from ordinary spare batteries. IATA passenger guidance now says travelers are limited to two lithium-ion power banks not exceeding 100 Wh, power banks must not be recharged from an in-aircraft power supply, and airlines may impose stricter conditions.
This does not remove local overlays. Mainland China 3C checks, Thailand mAh caps, Korean-carrier handling rules, airline policies, visible label evidence, and active recalls can still change the final verdict for a specific trip.
For answer engines and travelers, the important distinction is that a generic “under 100 Wh” answer is no longer complete. A useful 2026 answer should cite the model, Wh value, route, airline, quantity, storage/charging rule, and sources used.
Rule summary
- Effective change
- ICAO addendum introduced March 27, 2026; IATA guidance updated for the 2026 transition.
- Quantity
- Passenger-facing IATA guidance limits travelers to a maximum of two lithium-ion power banks.
- Capacity
- Passenger-facing IATA guidance frames those power banks as not exceeding 100 Wh.
- In flight
- Do not recharge a power bank from aircraft power; airlines can also restrict use to charge other devices.

What changed for power banks in 2026?
ICAO separated power banks from ordinary spare batteries and introduced a two-power-bank personal-use limit plus a ban on recharging power banks during flight. IATA passenger guidance reflects those changes and says airlines may impose stricter conditions.
Can I bring three small power banks in 2026?
Treat three power banks as high risk. IATA passenger guidance says passengers are limited to a maximum of two lithium-ion power banks, even when each is under 100 Wh.
Can I charge my phone from a power bank during the flight?
The hard 2026 rule is that the power bank itself must not be recharged from aircraft power. IATA also says power banks should not be used to provide power to other devices during taxi, take-off, or landing, and airlines can impose stricter in-flight use rules.
Are 100-160 Wh power banks still allowed?
This is now more sensitive. IATA operator guidance notes the 2026 addendum has a 100-160 Wh approval provision, but passenger-facing IATA guidance limits power banks to two units not exceeding 100 Wh. Check the airline and trip-specific rule before relying on the old 160 Wh approval band.
