【The 2025 New Regulations for Carrying Power Banks on Board】

Power Bank Carry-On Regulations (Latest Version for 2025)

1. Carrying Method and Placement
．Power banks must be carried in your hand luggage and are not allowed in checked baggage.
．Do not place them in the overhead compartment; they should be stored in carry-on bags under the seat.
．Using or charging power banks during the flight is prohibited; some airlines explicitly ban this behavior.

2. Capacity Limits (measured in Watt-hours, Wh)
．Under 100Wh: Can be freely carried without airline approval.
．100Wh to 160Wh (inclusive): Prior airline approval is required. A maximum of 2 units per person.
．Over 160Wh: Not allowed on board.

Conversion Formula for Capacity
Wh = Voltage (V) × Current (mAh) ÷ 1000
Example: 3.7V × 10000mAh ÷ 1000 = 37Wh

3. Quantity Limits
．Under 100Wh: Most airlines limit to a maximum of 5 units per person.
．100Wh to 160Wh (inclusive): Maximum of 2 units per person, with prior approval required.

4. Labeling and Packaging Requirements
．Power banks must be clearly labeled with their capacity (Wh). If there is no label, it is recommended not to bring them.
．Each unit should be individually packed to prevent short circuits, and must not be used during the flight.

5. Special Reminders
．Built-in batteries in smart luggage must be removed and carried separately.
．Some airlines (such as EVA Air) will ban the use of power banks during flights starting from March 2025.

To ensure smooth boarding, it is strongly recommended to check your airline's latest policies before departure and confirm that your power bank meets their specific requirements.
