AI-Powered supplier vetting

SummarySunstone Power Industry Co., Ltd. is identified as a factory and reports two China-based production facilities covering lead-acid and lithium batteries, with overseas entities in Germany and Indonesia. It has 20 years of stated energy-product experience, exports 90% of sales, and supplies customers in more than 100 countries. Reported certifications include ISO 9001, ISO 14001, and CE. The supplier offers broad customization, inventory capability, and overseas warehouse services. Production-related evidence includes one-month peak and off-season lead times, but no annual output quantity is provided; the available output field contains a monetary figure and is therefore omitted. Weaknesses or uncertainties include no written supplier-approval, corrective-action, complaint-handling, or service-assessment procedures, and unknown outsourcing-procedure and contract statuses. No specific customer cases are provided.

Supplier typeThe supplier is explicitly classified as a factory and is described as operating two factories in China: a lead-acid battery factory in Jiangxi and a lithium battery factory in Guangdong. Overseas companies in Germany and Indonesia indicate an international operating structure, but the supplied evidence does not establish whether all production is directly controlled by the stated company.

CertificationsThe supplier reports CE product compliance certification and ISO 9001 and ISO 14001 management-system certifications. These certifications provide explicit evidence of compliance and management-system credentials, although the specific certified products or certificate validity periods are not stated.

R&D capabilityThe supplier has a lithium battery production factory, offers multiple battery technologies including lithium-ion and LiFePO4 products, and reports R&D engineer experience of 6–10 years. These facts support product-development capability, but no evidence quantifies new-product launches, patents, dedicated R&D investment, or innovation outcomes.

Production capacityThe supplier reports two production factories, 20 years of energy-product experience, worldwide distribution, and one-month lead times in both peak and off-season periods. It also reports 6–10 quality-control staff and 6–10 years of R&D-engineer experience; however, annual production volume cannot be assessed because the provided output field is monetary and no unit-based capacity is stated.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. This is direct evidence of a broad customization service range.
