Sourcing Power Banks in China: Real Capacity, Safety First
We are not a factory. We are your Sourcing Agent in China, helping you filter out risky suppliers and verify Grade A battery cells in Shenzhen and Dongguan.
Why You Need a Sourcing Agent for Power Banks
The mobile power market in China is mixed. On platforms like Alibaba, trading companies often pose as factories. The biggest risks for importers are:
- Fake Capacity: A label says 10,000mAh, but the real capacity is only 6,000mAh.
- Safety Hazards: Poor quality PCB boards (protection circuits) can cause overheating or fire.
- Recycled Cells: Some workshops use second-hand battery cells to cut costs.
We protect your brand. We go to the production line to ensure what you buy is safe and compliant.
Our Technical Sourcing Standards
We focus on the “inside” of the product. Our sourcing process includes:
- Battery Cell Audit: We verify if the factory uses Grade A Li-Polymer or 18650 cells. We check the UL certificates of the battery cell suppliers.
- PCBA Inspection: We ensure the motherboard has essential protection ICs (Over-charge, Over-discharge, Short-circuit protection).
- Aging Test Supervision: We require factories to perform 100% burn-in tests (aging tests) for at least 4-8 hours before packing.
- Capacity Testing: We randomly pick samples and run discharge tests to verify the Real Capacity vs. Rated Capacity.
