AI-Powered supplier vetting

SummaryShenzhen Langbo Technology Co., Ltd. is identified as a Chinese manufacturer of adapters, chargers, switching power supplies, and related products. The supplier reports adapter output of 6,000,000 pieces, one-month lead times in both peak and off-peak seasons, and export sales of 31%–40%. SGS is listed as the audit organization, but the audit result and audit type are coded values without interpretable descriptions, and the stated report validity ended on 2025-01-10. Product development is described as a strength, supported by claims of a senior R&D team and rapid new-product response, although structured R&D indicators are largely unknown. Manufacturing information is inconsistent: one slice states seven employees and a 50.0 m² plant, while another describes approximately 150 employees, nine production lines, and 50 quality-control staff. Outsourcing, inventory, overseas services, OEM/ODM, traceability, and customer references are not sufficiently documented.

Supplier typeThe supplier is explicitly classified as a Manufacturer and is described as manufacturing, researching, and selling switching power adapters, chargers, and customized safety-standard power supplies. It is a limited company based in Shenzhen, China.

R&D capabilityThe company describes a senior R&D team specializing in power supplies, strong new-product development, rapid response, and awareness of international technology trends. However, the number of new products, ODM availability, SDK support, and other structured R&D indicators remain unknown, so the qualitative claims support potential but not a complete assessment.

Production capacityThe supplier reports adapter output of 6,000,000 pieces, one-month lead times in both peak and off-peak seasons, and nine production lines in one company description. Nevertheless, the records conflict on workforce and facility scale: one states seven employees and a 50.0 m² plant, while another states around 150 employees and 50 quality-control staff. The output and line information support production capability, but the contradictory scale data reduces confidence in the overall assessment.

Customization capabilityThe company description explicitly mentions customized safety-standard power supplies and reports new-product development capability. However, OEM and ODM availability are marked unknown, and no detailed customization process, engineering scope, or customization examples are provided.
