International security: the electronics playbook.
What's the same everywhere, and what varies between EU, UK, Japan, UAE, Singapore, and Australia.
What every airport asks for.
Laptops and tablets typically out of bags for X-ray (unless you have a domestic PreCheck-equivalent). Power banks and spare batteries always in carry-on. Liquids in 100 mL containers. Shoes typically stay on outside the US.
Where rules diverge.
EU: liquids 100 mL, electronics often pulled. UK: same as EU plus extra scrutiny on power banks. Japan: efficient and thorough — electronics out, batteries tray. UAE: very strict on labeling. Singapore: streamlined, follows ICAO precisely. Australia: strict on quantity, two-bank cap.
Pack for the strictest country on your route.

Is the Clutch Pro allowed on international 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.
