Taking a flight for leisure can be both exciting and stressful, so it’s essential to stay informed about the latest airline regulations, especially when it comes to carrying power banks. Recent incidents, such as the fire caused by a power bank in an overhead compartment on an Air Busan flight, have led to stricter rules. Here’s a guide to ensure a smooth journey with your power bank.
The Air Busan Incident
On January 28, 2025, a fire broke out on an Air Busan Airbus A321 at Gimhae International Airport. Investigations revealed that the fire was likely caused by a power bank stored in an overhead bin. This incident has heightened awareness about the risks associated with lithium-ion batteries on flights and prompted airlines to revise their regulations.
New Rules for Carrying Power Banks
Airlines, both Korean and foreign, have implemented similar rules to ensure passenger safety:

- Capacity Limits:
- Up to 100Wh: Allowed in carry-on luggage without prior approval.
- 100Wh to 160Wh: Allowed in carry-on luggage with airline approval.
- Above 160Wh: Prohibited.
- Carry-On Only:
- Power banks must be carried on your person or in your carry-on luggage. Storing them in overhead bins is prohibited.
- Usage Restrictions:
- Charging power banks during the flight is prohibited.
My Next Travel Plan: Flying with a Power Bank
As I prepare for my trip from Singapore to Seoul, I’ve made sure to check the capacity of my power bank. It’s a 20,000mAh power bank, which translates to around 74Wh, well within the allowed limit for carry-on luggage.
Before packing, I double-checked the airline’s specific rules on their website. They confirmed that power banks up to 100Wh are allowed without prior approval, so I’m good to go. I also made sure to pack my power bank in my carry-on bag, as placing it in checked luggage is a big no-no.
To avoid any issues at security, I’ve placed my power bank in a separate small bag within my carry-on. This makes it easy to remove and show to security officers if needed. I’ve also insulated the terminals with tape to prevent any accidental short circuits.

During the flight, I’ll keep my power bank in my personal item under the seat, as storing power banks in overhead bins is now prohibited. I won’t be using it to charge my devices during the flight, adhering to the new safety regulations.
