SummaryGuangzhou Senfly Technology Co., Ltd. is identified as a manufacturer/factory in Guangdong, China, specializing in automotive emergency power products such as jump starters and tire inflators. The supplier states that it has 15 years of experience in this area, nine production lines, 11–20 quality-control staff, 50 years of combined R&D engineer experience, and a 10,000-square-meter R&D and manufacturing center established in 2024. It reports annual product output of 2,000,000 jump starters and 1,000,000 tire inflators. The supplier also claims to accept ODM orders and possess more than 150 patented technologies. An SGS audit is recorded, but the provided data does not identify the audit result in interpretable terms or establish current certification validity. Information on after-sales services, financial credibility, customer cases, traceability, detailed R&D documentation, OEM, SDK, and overseas capabilities is insufficient.

Supplier typeThe supplier is explicitly identified as Guangzhou Senfly Technology Co., Ltd., a manufacturer/factory in Guangzhou, Guangdong, China. Its stated focus is automotive emergency starting power supplies and related automotive products, indicating direct manufacturing involvement rather than only trading or distribution.

R&D capabilityThe supplier states that it has focused on automotive emergency starting power supplies for 15 years, employs R&D engineers with 50 years of total experience, operates a 10,000-square-meter R&D and manufacturing center established in 2024, and has more than 150 patented technologies. These statements provide explicit evidence of established R&D activity and patent output, although detailed innovation documentation and new-product launch data are unavailable.

Production capacityThe supplier identifies itself as a manufacturer/factory with nine production lines and a new 10,000-square-meter R&D and manufacturing center. Reported annual output includes 2,000,000 jump starter sets and 1,000,000 tire inflator sets, supporting a substantial production capability for its stated product categories.

Customization capabilityThe supplier explicitly states that it accepts ODM orders, which supports product customization. However, the slices do not confirm private-mold development, 3D design services, OEM execution, or detailed customization workflows, so the evidence supports ODM availability but not the full range of customization services.
