How do you keep a wireless charger OEM order aligned with the approved sample? Freeze a dated configuration record, identify the physical reference sample, and agree that substitutions need review before they enter the order. A model number and a beauty photograph alone do not define the complete production version.
Shinestone is an OEM/ODM wireless charger manufacturer and supplier. When preparing a sourcing project with Shinestone, connect the selected model to its sample revision, specifications, power accessories and buyer-approved artwork. The workflow below is a proposed purchasing method; agree the actual document access and approval responsibilities for your project.
1. Separate the model number from the approved revision
The model identifies the product family. The revision identifies what you accepted for this order. Give the approval pack a date and version, and record who approved it. Keep a reference sample with identifying photographs; if buyer and supplier retain separate samples, agree how those samples are matched.
A sample-testing checklist asks whether a sample meets your requirements. Change control answers a different question: what happens when a component, firmware setting, accessory or artwork changes after that approval?
| Approval item | Record before production | Review if it changes |
|---|---|---|
| Product identity | Model, revision, sample ID, dated photographs and approved specification | Confirm which order quantities use the revised version |
| Charging configuration | Agreed input profiles, charging positions and intended device/case combinations | Repeat the affected functional checks under the agreed conditions |
| Internal configuration | Available component or assembly identifiers and firmware/configuration reference | Ask engineering to assess the effect of a substitution |
| Accessories | Exact cable, any included adapter, plug version and packing list | Review the charger and power-source combination together |
| Appearance and mechanics | Approved finish, dimensions, joints, mounting parts and logo placement | Check fit, stability, clearances and artwork against the reference |
| Documents and packing | Applicable model/revision references, instruction version and final artwork files | Check the scope of documents and replace superseded files |
You do not need to assume access to a supplier’s entire confidential bill of materials. Agree which identifiers and change notices can be shared, and how the supplier will identify the approved assembly internally.
2. Treat a substitution as a review trigger
Ask for a short written change request: the part or file affected, old and proposed revisions, reason, affected orders, proposed validation and the approval needed. A buyer should be able to accept it, ask for evidence, or defer it without the discussion becoming an undocumented production instruction.
The Wireless Power Consortium explains that housing materials, coil and shielding positions, and firmware differences can affect wireless power transfer. Using components found in another certified product does not automatically establish compliance for the assembled charger. This is a reason to review the affected configuration, not evidence that every change requires the same test plan.
Where certification is part of the purchase requirement, ask the responsible certification provider to confirm the effect of the proposed change. WPC’s certification verification guidance directs buyers to match the product to its registration record. Neither a printed logo nor a generic component certificate establishes that the selected model and version are covered.
3. Apply the record to the actual product format
For SST-WXC2651, the published listing describes a round-base 3-in-1 stand, USB-C input at 9V/2A, and listed phone output modes up to 15W. Its catalogue configuration describes fan and semiconductor cooling. An approval pack should identify the chosen cooling assembly, watch configuration and power setup; these listing details are not controlled test results.
For SST-WXC2701, the published version is a 15W max clamping car wireless charger with one-touch release and a suction-cup mount. Include the approved mounting arm, clamp fit and release operation in its revision record. Do not substitute a vent mount or a different release mechanism without reviewing that change.
These examples show why one generic approval sheet should not silently cover both a desktop stand and an in-car cradle. Check current model specifications and the selected sample before agreeing an order.
4. Link inspection and repeat orders to the approved pack
Give the inspector the approved revision, sample photographs, acceptance method and final packing list. Ask the supplier to identify the batch and configuration used for the shipment. When a discrepancy appears, record the affected units and resolve it against the agreed reference before shipment approval.
For a repeat order, confirm whether the approved configuration remains available. Review later changes explicitly rather than assuming last season’s sample covers every future batch. Keep superseded artwork and specifications marked as obsolete so they cannot be mistaken for current instructions.
Use the sample-testing checklist to define functional checks and the compliance-document guide to organize model- and market-specific evidence.
Buyer questions
Does an approved sample prevent all production changes?
No. Its value is a shared reference. A written review process makes proposed changes visible and records what the buyer accepted for each order.
Is a new model number required for every revision?
Not necessarily. Agree a traceable revision system appropriate to the change, and confirm any identification requirements with the responsible documentation or certification provider.
Is the same output rating enough to approve a replacement part?
No. The stated rating alone does not show that the assembled configuration behaves the same with the intended devices, power source and mounting arrangement. Review the affected functions and supporting evidence.
