AI-Powered supplier vetting

SummaryMaoxin New Energy is an inverter-power and emerging-energy-technology supplier with stated OEM/ODM experience and broad product and technical-service activities. It holds ISO 9001 certification, operates one production line, and reports one quality-control inspection staff member, six test-equipment units, and one R&D engineer. The supplier offers flexible customization and provides technical support for production and after-sales service. However, it has only one year of export experience, no stated SDK availability, no valid manufacturing-capacity contract with related subcontractors, and no in-stock, overseas warehouse, or overseas showroom capability. It reports no cooperation with Fortune 500 companies. Financial information is present only as year labels, which is insufficient to assess credibility.

Supplier typeThe supplier is a manufacturer and technical-service provider focused on emerging energy technologies, power electronics, batteries, distribution switch-control equipment, and related components. Its stated ambition and industry positioning center on inverter power, while the available information does not establish whether it is a trading company or manufacturer-only entity.

CertificationsThe supplier reports holding ISO 9001 certification. This explicitly supports the presence of a recognized quality-management-system certification, although no certificate scope, issuing body, or validity details are provided.

After-Sales capabilityThe R&D engineer is responsible for technical support for production and after-sales service, and technical services are included in the business scope. However, the supplier reports no in-stock service capacity and no overseas warehouse or showroom, so the evidence supports technical after-sales assistance but not comprehensive local or inventory-based service coverage.

R&D capabilityThe supplier states that innovation and R&D are central to its development, conducts emerging-energy-technology research, and has one R&D engineer responsible for customer-request confirmation, product design, and technical support. It plans further R&D investment, but reports no available SDK, so its innovation capability is supported at a basic product-development level rather than a demonstrated software-development platform level.

Production capacityThe supplier lists welding, cutting, bending, drilling, and soldering equipment, operates one production line, and has written warehouse-control procedures with retained records. Production quality resources are limited to one inspection staff member and six test-equipment units, while no valid manufacturing-capacity contract with related subcontractors and no in-stock capacity are reported; overall production capability is evidenced but limited in scale and support flexibility.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. Its R&D engineer is responsible for confirming customer requirements and designing new products, directly supporting the stated customization services.

Client casesThe supplier states that it provides long-term OEM/ODM services to numerous prominent domestic and international new-energy enterprises and offers OEM services for well-known brands. However, it reports no cooperation with Fortune 500 companies and provides no named customer cases, so the breadth of experience is asserted but independently specific case evidence is limited.

Product Q&A

Q:What certifications do your products have?

All products are CE, RoHS, UL, FCC, and CCC certified. ISO 9001 certification demonstrates our robust quality management system.

Q:Can the power supply be customized?

Yes, you can specify input/output voltage, power, waveform type, size, and special features, and we will design and produce according to your requirements.

Q:What is the efficiency of the power supply?

Our high-quality power supplies are highly efficient. Efficiency can reach over 90%, with some even reaching around 95%.

Q:Why is there no output from the device?

This could be due to loose input connections, a blown fuse, switch failure, or internal circuit malfunction. The fuse blows quickly during short circuits or overloads.

Q:What should I do if the output voltage is unstable?

Check the input power supply and battery level. If using rectified DC, install a voltage stabilizer. Avoid exceeding rated output power. Internal faults require professional inspection.
