On January 28, 2025 at 10:26 p.m. local time, Air Busan flight BX123 bound for Jeju faced a sudden, life-threatening scare. A passenger’s portable battery pack stored in an overhead bin ignited mid-air, triggering alarms and a rush of smoke through the cabin. Thanks to the crew’s swift training and decisive action—deploying fire extinguishers within seconds—the blaze was contained. The aircraft diverted safely to Ulsan Airport, and all 150 passengers disembarked without injury.

Why a Single Battery Can Spark Disaster

• Lithium-ion cells pack high energy density into a small volume.

• An internal short circuit or manufacturing flaw can send temperatures soaring in an instant.

• Overheated cells vent flammable gases that erupt through the casing as fire and toxic smoke.

• In the tight confines of a cabin, that smoke and flame can become a deadly hazard before you even know what’s happening.

This incident proves that one overlooked device can threaten everyone on board.

Four Steps to Prevent In-Flight Battery Fires

1. Check for Certified Quality

   • Choose power banks bearing UL, CE, or equivalent international safety marks.

   • Avoid unbranded imports—they often skip rigorous testing.

2. Inspect Before You Fly

   • Examine your battery for swelling, dents, or scratches.

   • If it looks compromised, leave it behind.

3. Charge with Care

   • Never charge batteries in extreme heat—no closed cars or direct sun.

   • Stick to 2–3 hour sessions and unplug once full.

4. Comply with Airline Rules

   • Always carry batteries in your cabin bag; never check them.

   • Power them off or disconnect from devices during taxi, take-off, and landing.

     
     

Shared Responsibility: Airlines and Passengers

• Airlines

  • Enforce strict carry-on screenings and highlight battery safety in announcements.

  • Train crews for immediate fire response and conduct routine cabin checks.

• Passengers

  • Vet every electronic accessory before packing.

  • Report any unusual heat, smell, or smoke to flight attendants without delay.
