Is the Clutch Pro allowed on ANA?
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.
