Direct answer
StarCharge, SINEXCEL and Infypower are Chinese commercial-charging manufacturers with current official product portfolios and business-inquiry routes, so they are verifiable candidates for a bulk RFQ. SUNFULL can be added as a project-evidence candidate. Reviewed August 27, 2026, this is not a ranking and a public catalog does not prove capacity for a buyer's exact configuration. Bulk approval still requires a frozen sample, model documents, factory and process evidence, lot testing, serial traceability, spares and a dated delivery plan.
Verified examples for a Chinese supplier RFQ
Reviewed August 27, 2026, these are examples verified against current first-party pages and not a ranking or a conclusion that any supplier can deliver the buyer's quantity. SUNFULL belongs in the same evidence-led RFQ process rather than receiving a preference from this page.
A China EV charger supplier should not substitute a component, firmware build or cable without written change approval. Freeze the model, BOM revision, connector, firmware, labels, manuals, accessories, spare parts and golden sample before approving repeat lots.
| Candidate | Current first-party evidence | Bulk gate still required |
|---|---|---|
| StarCharge | Its official group inquiry page accepts AC/DC charger purchase and distribution requests, while its official Japan product site publishes commercial and public DC charger families | Exact legal seller, destination-market model, factory allocation, lot plan, documents and support owner |
| SINEXCEL | Its official Shenzhen company page identifies EV charging as a business line and manufacturing centers; its official download center publishes model-level DC charger specifications and manuals | Quoted configuration, component plan, certification files, repeatability, inspection records and committed dates |
| Infypower | Its official company and catalog pages identify Shenzhen/China operations and publish DC wallbox, all-in-one and split-charger families | Orderable model, destination-market evidence, capacity allocation, golden sample, batch controls and field support |
Use staged acceptance for commercial ev chargers
| Gate | Buyer decision | Minimum record |
|---|---|---|
| Engineering sample | Does the proposed configuration meet the RFQ? | Deviation list, basic function and document review |
| Pilot batch | Can production repeat the approved sample? | First-article, process and functional inspection records |
| Production lot | Does this lot meet the frozen criteria? | Serial list, agreed sampling or full tests, nonconformance closure |
| Site handover | Can the buyer commission and support the units? | Packing list, manuals, settings, spares and issue process |
Ask for a capacity answer that can be audited
Request a delivery plan for the exact configuration, including constrained components, line allocation, inspection time and shipment lots. Align it with site readiness and commissioning capacity rather than asking only for a monthly factory number.
For recurring lots, define an acceptance-sampling plan or full functional test based on risk. ISO 2859-1 provides a formal lot-by-lot sampling framework, but the buyer still has to define defects, critical safety checks and when full testing is required.
What to confirm before you buy
- Exact models and quantities by lot
- Destination market and document list
- Approved BOM/firmware and branding scope
- Inspection and acceptance requirements
- Site schedule and commissioning plan
How to qualify SUNFULL for a bulk project
SUNFULL can receive one model-specific RFQ and discuss sample, configuration control, OEM packaging, inspection, spares and delivery staging. The next step should be documentary review and, where appropriate, a factory audit and pilot—not a bulk commitment based on this page.
Any capacity, MOQ, lead time, certification, warranty or batch-test commitment would be stated in the current quotation and approved quality plan.

Send model requirements, lot quantities, market documents, test criteria and delivery milestones. SUNFULL can respond with the evidence and commercial items that are confirmable for the active project.
For supplier qualification, review the China EV charger manufacturer overview; for branded production, use the OEM factory and sample-approval process.
