Your phone's lifeline just got stricter. Beginning 15 April 2026, anyone flying out of Singapore's Changi Airport can pack exactly two power banks in their carry-on bag. Not three. Not five. Two. The Civil Aviation Authority of Singapore (CAAS) has drawn a line in the sand, and the decision comes directly from real-world disasters.
The culprit behind this tightening? Lithium batteries. A blaze that tore through an Air Busan aircraft in January 2025 and a power bank fire aboard an Air China flight that same year exposed just how dangerous these portable chargers can be when things go wrong at cruising altitude. Trapped in a pressurized cabin with nowhere to land quickly, a lithium battery fire becomes a nightmare scenario. CAAS director Foong Ling Huei put it plainly: "The new requirements will help reduce the risk of fire caused by power banks on board flights."
How this ripples across the region
Singapore isn't alone in tightening the screws. Japan and Macao have already restricted power bank quantities and charging. Hong Kong went even further, banning passengers from using power banks mid-flight altogether. The Asia Pacific region has become the early adopter of stricter battery rules, setting a template that global aviation is now following.
The International Civil Aviation Organization (ICAO) finally formalized guidelines on 2 April 2026, establishing the two power bank maximum and restrictions on mid-flight charging and use. Major carriers including Virgin Australia, Qantas, Jetstar, Lufthansa Group, and Emirates have already announced compliance. Singapore Airlines quickly issued updated guidelines following ICAO's framework, signaling that this isn't a temporary measure.
What you need to know before you fly
Here's the practical breakdown. Power banks must travel in your carry-on, never in checked baggage (every airline prohibits that). Your devices also face capacity limits. Any power bank exceeding 100Wh requires special written permission from your airline before boarding, which means most travelers won't bother attempting it. Throw your chargers into protective cases or pouches to prevent short circuits during turbulence.
The chain reaction started in September 2025 when the U.S. Federal Aviation Administration (FAA) issued a Safety Alert for Operations (SAFO) warning about lithium battery hazards. China's Civil Aviation Administration followed by banning uncertified power banks on domestic flights, allowing only those carrying valid China Compulsory Certification (3C or CCC) markings.
What this means for frequent travelers
If you're one of those people who plugs into every outlet between here and your destination, this hits differently. You're now forced to choose wisely between two devices. Bring your main portable charger and maybe a backup, but you're out of luck if you traveled with multiple units for friends, family, or redundancy. Some travelers will need to rethink their packing strategy entirely.
Changi Airport's full advisory on the new rules confirms that enforcement begins immediately for all departing passengers. Pack smart, charge your devices before heading to the gate, and remember that lithium batteries don't care about your tight connection or important work emails. Safety comes first, always.
The battery wars in aviation just entered a new chapter. What started as warnings has become hard rules that affect how you pack for every flight. Welcome to 2026 air travel.
