The 24-Hour Essentials Rule in Your Personal Item
Always pack prescription medications in original labeled bottles, passport + backup copy, portable USB-C power bank (must be carried in the cabin, never in checked luggage), toothbrush/skincare under 100 ml, eyeglasses/contacts, and 1 complete change of clothes in your cabin bag.
Why Lithium Battery Power Banks Are Prohibited in Checked Bags
FAA, EASA, and ICAO safety regulations strictly forbid spare lithium-ion power banks and e-cigarettes in checked luggage. Keep all power banks under 100 Wh (approx. 27,000 mAh) in your under-seat personal item.

Frequently Asked Questions
Can I bring a 20,000 mAh portable charger on an international flight?
Yes, a 20,000 mAh (approx. 74 Wh) power bank is well below the universal 100 Wh cabin limit and must be carried in your cabin baggage.
Do I need a voltage converter for phone, laptop, and camera chargers?
Modern USB-C laptop and phone power bricks are dual-voltage (100V–240V, 50/60Hz) and only require a plug adapter; high-wattage hair straighteners or dryers require dual-voltage ratings.
