AI-Powered supplier vetting

SummaryShenzhen Gold Power Tech Co., Ltd. is identified as a Chinese manufacturer established in 2001 in the company profile, while another description states operations began in 1995. It has approximately 487 employees, an independent 80,000-square-meter industrial park, about 100 R&D engineers, and stated annual power-supply capacity of 6 million units. Its products cover power supplies, EV chargers, energy storage systems, UPS products, and related solutions. The supplier reports ISO9001 approval and holds ISO14001:2015, ISO45001:2016, and IATF16949 certifications. Export activity is stated across more than 30 countries and regions, with shipment records showing repeated traffic-control power-supply shipments to the United States through Shenzhen/Yantian ports for one named buyer. Evidence supports manufacturing scale, relevant certifications, R&D resources, and international shipment experience. After-sales capability and financial credibility are not sufficiently documented.

Supplier typeThe supplier is explicitly classified as a manufacturer, with a factory in Shenzhen, an independent industrial park, and stated production of power supplies. Its product scope is concentrated in power electronics and related systems, supporting a direct manufacturing role rather than a trading-only profile.

CertificationsThe supplier reports ISO9001 approval and lists ISO14001:2015, ISO45001:2016, and IATF16949 certifications. These certifications provide explicit evidence of formal quality, environmental, occupational-safety, and automotive-sector management systems, although certificate validity and scope are not further detailed.

R&D capabilityThe supplier reports 100 R&D engineers, many core intellectual property rights, national high-tech enterprise status, and more than 20 years of power-supply industry practice. These statements explicitly support meaningful R&D and innovation resources, although no specific patents, product innovations, or R&D outcomes are provided.

Production capacityEvidence indicates approximately 487 employees, an 80,000-square-meter industrial park, stated capacity of 6 million power-supply units annually, and a Shenzhen factory location. The supplier also reports exports to more than 30 countries and regions, supporting substantial production scale and operating experience.

Customization capabilityThe product keywords explicitly include customized power supply, and the company presents itself as an integrated power-supply solutions partner. This supports the existence of customization offerings, but the slices do not specify engineering processes, customization limits, or examples of customized products.

Client casesThe supplier states that its products are exported to more than 30 countries and regions. Four 2025 shipment records identify power supplies for traffic-control equipment, shipped through Shenzhen/Yantian ports to the United States for Jasper Electronics Inc., providing concrete evidence of repeat international customer activity in a relevant product category.
