From April 15, 2026, passengers flying out of Singapore will only be allowed to carry a maximum of two external batteries in their cabin baggage. This move, which reflects the global tightening of safety requirements in response to lithium battery fire risks on aircraft, is being implemented by the Civil Aviation Authority of Singapore (CAAS) in line with new standards from the International Civil Aviation Organization (ICAO). Passengers will have to surrender any additional devices before boarding. External batteries must be placed in carry-on bags and remain prohibited in checked luggage. The terminals of these batteries must be protected to prevent short circuits. The new thresholds do not fundamentally change the capacity rules but tighten their use. Power banks of 100 Wh or less remain allowed in the cabin, limited to two units per person. Between 100 Wh and 160 Wh, they can only be carried with the prior approval of the airline. Above 160 Wh, external batteries are strictly prohibited for passengers. This measure aims to reduce fire risks while continuing to meet the needs of travelers. Passengers will no longer be able to recharge their power banks on board or use them to power their electronic devices once the aircraft door is closed. The Civil Aviation Authority of Singapore plans a large information campaign at Changi Airport to minimize unpleasant surprises during security checks. Carriers operating in Singapore have also been asked to relay the new rule in advance. Security agents will be trained to apply these restrictions in a 'smooth and orderly' manner.
