Short answer: In 2026, the safest public rule is: keep each power bank at 100 Wh or less unless your airline explicitly permits otherwise, carry power banks in cabin baggage only, do not recharge a power bank from the aircraft power supply, treat two units as a conservative planning limit unless your airline says otherwise, 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. The cited IATA passenger battery guidance supports the 100 Wh planning threshold and airline/operator handling controls; quantity still has to be checked against the operating airline and route rather than treated as one global country-agnostic cap.
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
- Treat quantity as airline-specific; two units is only a conservative planning assumption unless the carrier publishes a different allowance.
- 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 tightened passenger handling expectations. Treat quantity as airline-specific because the cited IATA battery document is strongest on Wh thresholds and handling, not a universal country-level quantity cap.
Can I bring three small power banks in 2026?
Treat three power banks as high risk. Some airline and passenger-facing materials use a two-unit planning limit, but that is not a universal ICAO/IATA cap; check the operating airline before relying on it.
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 power-bank planning should not treat that older approval band as automatic. Check the airline and trip-specific rule before relying on 160 Wh language.
