Amidst increasing product homogeneity, Dongguan Sanshang Electronics prioritizes technological innovation and quality safety. We are proud to announce that all of our power banks have passed the testing and certification of China's national standard GB/T 35590-2017, "Information Technology - General Specification for Power Banks for Portable Digital Devices."

This certification sets extremely stringent requirements for power banks, including rated capacity, conversion efficiency, safety protection, and material flame retardancy. This certification ensures that Dongguan Sanshang Electronics' products meet authoritative national standards for safety, reliability, and performance, safeguarding the safety of customers and consumers.

Furthermore, to completely address the industry's pain point of inflated capacity labels, we have invested in a world-leading lithium battery capacity sorting system. Each battery cell undergoes 100% charge and discharge testing before assembly. We precisely select cells with the highest consistency in capacity and internal resistance for pairing. This ensures that the actual discharge capacity of our products exceeds the nominal capacity, giving your customers peace of mind.

We understand that safety and integrity are the cornerstones of any partnership. Dongguan Sanshang Electronics is committed to building long-term, stable partnerships with you through transparent data and uncompromising quality.

In today's society, power banks have become an indispensable necessity, not only for daily life but also for travel. As air transport requirements evolve, Dongguan Sanshang remains compliant with regulatory requirements, ensuring that all its products meet air transport standards.
