A sound quality control mechanism has been set up with detailed inspection procedures, fully implementing multiple testing processes including IQC (incoming quality control) material inspection, full on-line inspection, and finished product sampling inspection.

Raw Material and In-Process Inspection
Before each batch of raw materials enters the workshop, they undergo rigorous tests with professional testing equipment to prevent non-conforming materials from entering production. During manufacturing, dedicated inspectors carry out continuous patrol checks to monitor assembly craftsmanship and performance parameters in real time, guaranteeing that all working procedures meet quality specifications.

Final Product Testing
Prior to delivery, finished products go through comprehensive aging tests, performance assessments, and safety inspections via our 15 professional aging test racks. These tests fully verify the products' battery life, charging efficiency, stability, and safety. By implementing strict quality checks from raw material intake to finished goods shipment, we fully ensure that every delivered item features premium quality, reliable safety, and compliance with relevant domestic and international certification standards.
