Tokyo Narita & Haneda power bank rules, 2026.
What Japan's CAB allows and what ANA and JAL enforce at NRT and HND.
Two banks, in-flight use banned (ANA/JAL).
Japan’s Civil Aviation Bureau adopted the ICAO framework on April 24, 2026. ANA and Japan Airlines limit passengers to two power banks under 100 Wh in carry-on, with no in-flight use permitted.
Smooth screening, strict cabin rules.
Japanese airport security is methodical — pull your power bank out of your bag at the tray. The strictness comes once you board: no using the bank during flight on either ANA or JAL. Top up before boarding.

Is the Clutch Pro allowed on Japan flights?
Yes. The Clutch Pro is approximately 18.5 Wh (5,000 mAh × 3.7V), well under the 100 Wh carry-on limit every major airline uses.
Can I put a power bank in checked luggage?
No. Lithium-ion batteries must always travel in carry-on luggage. This is an FAA, EASA, CAA, and ICAO rule — no airline allows it.
How do I convert mAh to Wh?
Wh = (mAh ÷ 1000) × voltage. For lithium-ion power banks, voltage is typically 3.7V. So 5,000 mAh ≈ 18.5 Wh, 10,000 mAh ≈ 37 Wh, 27,000 mAh ≈ 100 Wh.
What if my power bank is over 100 Wh?
Power banks between 100–160 Wh require airline approval and are limited to two per passenger. Anything over 160 Wh is banned from passenger aircraft.
