Can You Use a Power Bank on a Plane in 2025?
Therefore, airlines have strict regulations regarding the energy, quantity, and certification of power banks. As a leading power bank manufacturer, we're often asked by foreign trade clients and gift companies, "What kind of power banks are allowed on board?"
Energy Limits and Carry-On Quantity
Power banks with an energy level ≤ 100Wh can be carried directly on board. Power banks with an energy level 100Wh or less and an energy level ≤ 160Wh can be carried on board with airline approval. Power banks with an energy level > 160Wh are prohibited.
Important Notes:
- Prohibited from Use: Power banks must be turned off throughout the flight to prevent accidental activation.
- Prohibited from Checked Baggage: Power banks are not permitted in checked baggage and must be carried on board. Large quantities must be shipped via dangerous goods shipping channels (each box ≤ 10kg).
- Appearance Requirements: Power banks must be in good condition, free of bulges, leaks, or cracks, and clearly labeled.
How do I calculate energylevel (Wh) of my power bank?
Formula: Wh = V (voltage) × Ah (ampere-hour) or Wh = V × (mAh / 1000)
Example: 20,000mAh (20Ah), 3.7V power bank: 3.7V × 20Ah = 74Wh (≤100Wh, portable)
Tip: Common 10,000mAh/20,000mAh power banks (voltage 3.7V/5V) are generally under 74Wh and can be safely carried.
Certifications should be selected based on the target market.
For example: CE (EU), UL (US), PSE (Japan). Specific certification requirements are as follows:
List of Major Certifications in Global Markets
EU
- CE-EMC, CE-LVD
Mandatory Certification: CE logo alone does not guarantee true compliance; a NB number is required.
- RoHS
Recommended Certification: Environmental certification, Restriction of Hazardous Substances
US
- UL2056
Highly Recommended: Product Safety Certification
- FCC
Mandatory Certification: Testing for electromagnetic compatibility and electromagnetic radiation issues
Japan
PSE Roundel
Mandatory Certification: Power banks only require the PSE roundel (for non-specific electrical appliances)
South Korea
KC
Recommended Certification: Enhances product competitiveness
Global Aviation
- UN38.3
Mandatory Certification: Lithium battery transportation safety testing, required for air transport
- MSDS/SDS
Required Document: Chemical Safety Data Sheet
Note: Uninstalled lithium batteries with more than 24 cells or 12 batteries per package must pass a 1.2m drop test.
