Powerbank Flight Regulations Require Hand Luggage and Capacity Limits

Airlines worldwide require portable powerbanks to be carried in hand luggage, not in checked baggage, because lithium‑ion cells can overheat and cause fires. The International Air Transport Association (IATA) sets the baseline rules, while national safety authorities such as Germany’s TÜV Verband emphasize the fire risk. Powerbanks up to 100 Wh may be taken on board without special permission; devices between 100 Wh and 160 Wh need airline approval, and any unit above 160 Wh is prohibited. Travelers must inspect batteries for damage, swelling, or exposed contacts and keep terminals separated from metal objects. A recent incident in which a Swiss flight en route to the United States was diverted after a headphone charger ignited underscores the importance of these precautions. Passengers are advised to verify airline‑specific limits before travel.
