How to store Korean airplane batteries(Power Bank)

Using a power bank on an airplane is no longer as simple as it once was. Due to an increasing number of in-flight fire incidents in recent years, airlines worldwide have strengthened regulations regarding power banks. In particular, South Korea’s new regulations, effective March 1, 2025, have established stricter standards for storing and using power banks on flights. This guide provides the latest regulations and practical tips for safely using power banks on airplanes.

Power Bank Usage Regulations

1. Power Bank Capacity Limits

The maximum allowed power bank capacity on airplanes is 160Wh.

✅ General Regulations

• Below 100Wh: Allowed up to five (5) units.
• 100Wh – 160Wh: Allowed up to two (2) units (requires airline approval).
• Above 160Wh: Not permitted on board.

✈️ Airline-Specific Variations Different airlines may have additional restrictions, so it’s crucial to check the airline’s power bank regulations before boarding.

2. Proper Storage of Power Banks

Ensuring safe storage of power banks on airplanes is essential.

✅ Storage Guidelines

• Do not store in overhead bins → Keep in seat pockets or carry-on bags.
• Protect battery terminals → Use insulating tape or individual plastic bags.
• No checked baggage → All power banks must be carried in hand luggage.

✈️ Why Terminal Protection is Necessary If metal objects come into contact with a power bank’s terminals (charging ports), a short circuit can occur, leading to potential fire hazards. To prevent this, it’s mandatory to cover terminals with insulating tape or keep power banks in separate protective packaging.

3. Charging Power Banks During Flights is Prohibited

It is strictly prohibited to charge power banks during flights.

🚫 Restrictions

• Using USB ports or power outlets on the plane is not allowed.
• Charging one power bank using another power bank is also forbidden.

✅ Alternative Solutions

• Fully charge your power bank before boarding.
• Use alternative charging methods like laptops (if airline regulations allow it).

✈️ Why In-Flight Charging is Banned Charging power banks in-flight increases the risk of overheating and potential fire hazards. It is safest to charge them before boarding and use them only when necessary.

4. What to Do in Case of Malfunctions

If a power bank overheats, swells, or shows any signs of damage during the flight, immediately inform a flight attendant.

🚨 Signs of Power Bank Malfunctions

• Noticeable swelling or bulging of the battery.
• Unusual or burning smell coming from the device.
• Visible smoke emissions from the power bank.
• The power bank becomes too hot to touch.

✅ Steps to Take

1. Immediately stop using the power bank and turn it off.
2. Separate it from other electronic devices and avoid contact with metal objects.
3. Inform a flight attendant immediately for proper handling.

✈️ Additional Safety Measures Some airlines have onboard fire-resistant battery containment bags (Li-Po Safe Bags) to manage potential fire hazards. Follow crew instructions if an emergency occurs.

Practical Tips for Safe Power Bank Use on Airplanes

✅ Pre-Flight Preparation

• Ensure the power bank is fully charged before boarding.
• Carry insulating tape or individual protective bags for battery safety.
• Check how many power banks are allowed for your flight.
• Review your airline’s latest policies to avoid unnecessary issues.

✅ In-Flight Precautions

• Store power banks in seat pockets or carry-on luggage for easy access.
• Monitor battery temperature regularly and report any abnormalities.
• Before using, confirm airline policies on power bank usage.

✅ Additional Safety Considerations

• Inspect power banks before boarding to ensure they are undamaged.
• Turn off power banks when not in use to prevent accidental activation.

Conclusion: Follow Regulations for a Safe Flight

Using power banks on flights is no longer a simple matter. Regulations worldwide are becoming stricter, and South Korea’s 2025 updates have introduced even tighter restrictions on power bank storage and use.

✈️ Key Takeaways

• Up to 5 units under 100Wh, up to 2 units (100–160Wh) with airline approval.
• Power banks must not be checked in; only carry-on is allowed.
• Protect battery terminals with tape or protective packaging.
• Charging during flights is strictly prohibited.
• Report any overheating, swelling, or malfunctions to flight attendants immediately.
