Because power banks contain lithium batteries, they pose certain safety risks in harsh environments like high altitudes and low pressure.
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.
