Behind The Ban on Non-3C Certified Power Banks: Who’s Safeguarding Power Bank Safety?

Recently, the Civil Aviation Administration of China (CAAC) issued a notice prohibiting passengers from carrying power banks without a 3C mark, with unclear markings, or from recalled models on domestic flights. This policy highlights the growing concern over the safety and reliability of power banks. To obtain 3C certification, power banks must undergo a series of rigorous tests, placing high demands on the sealing, structural strength, and durability of testing equipment.

Four Key Stages of 3C Testing:

Battery Safety Testing: Simulates extreme scenarios like explosion and fire. Testing is conducted in sealed chambers to prevent risk leakage.

Electrical Safety Testing: Simulates electrical faults through high-voltage breakdown and short circuit; equipment must feature excellent grounding and sealing.

Environmental Adaptability Testing: Uses constant temperature and humidity chambers to simulate various climates and assess structural stability.

Durability Testing: Employs vibration tables and high-temperature platforms for long-duration operation to ensure continuous, stable performance.

These testing devices are structurally complex and demand meticulous attention to detail. Their stable operation relies heavily on the support of precision-engineered hardware components.

✅ Panel Locks: Ensure airtight closure of testing chambers, preventing external air, dust, or temperature interference with test data.
✅ Butt Hinges: Maintain long-term durability under frequent door operations, keeping structural integrity intact.
✅ Leveling Feet: Provide stable support for heavy-duty equipment, minimizing vibration and ensuring accurate test results.
