Selecting wireless charger suppliers requires evaluating certifications like Qi, CE, and FCC, production capacity above 50,000 units per month, on-time delivery rates over 98%, low MOQs starting at 200pcs, robust quality control, and OEM/ODM customization. Shenzhen factories like Wecent offer reliable B2B production, rapid prototyping, and global shipping, making them ideal partners for wholesalers seeking consistent, certified, and scalable solutions.
What Certifications Matter Most?
Essential certifications include Qi for compatibility, CE/FCC for safety, RoHS for material compliance, and ISO 9001 for quality management systems. Suppliers with these credentials ensure regulatory compliance and smooth market entry for global B2B orders.
Shenzhen manufacturers excel in multi-certification setups. Qi ensures interoperability with devices like iPhones and Samsung phones, while FCC regulates EMI critical for wireless technology. Wecent maintains Qi, CE, FCC, RoHS, PSE, and KC certifications, validated by SGS and TÜV labs. Verifying these through WPC databases and scope reports ensures authenticity and reduces compliance risks for wholesalers.
Factory audits and testing frequency reviews confirm quality and legitimacy. Certified OEM partners streamline export approvals and prevent delays in bulk shipments.
| Certification | Requirement | Benefit |
|---|---|---|
| Qi | WPC Membership | Device compatibility |
| CE/FCC | EMC/Safety | Global market access |
| RoHS | Materials | Environmental compliance |
| ISO 9001 | QMS | Process reliability |
What Production Capacity Is Needed?
Reliable suppliers must support 50,000+ units per month, equipped with SMT lines, cleanrooms, and automated assembly for precision. Shenzhen factories scale from prototypes to full wholesale orders efficiently.
Evaluate high-speed assembly for GaN wireless chargers. Wecent produces 10,000–100,000 units monthly, with vertical integration for PCBs and casings. Facility tours, DFM reports, and production videos help verify scalability and avoid bottlenecks during peak demand.
How to Assess Quality Control Processes?
QC includes raw material inspections, automated optical inspection (AOI), 100% burn-in testing, and efficiency checks exceeding 80%. Defect rates below 0.5% indicate superior performance.
Thermal imaging detects overheating risks, while Wecent implements multi-stage inspections including FOD detection and drop tests. Third-party audits from labs like Intertek and traceable SPC charts ensure confidence in large-scale wholesale orders.
What Delivery Performance to Expect?
Expect on-time delivery rates above 98%, with typical lead times of 7–35 days. ERP systems in Shenzhen factories enable reliable global shipping.
Stock models can ship within 7 days, while custom OEM products take 25–35 days. Wecent achieves 99% on-time delivery using dual sourcing and port proximity. Reviewing historical performance metrics helps assess reliability, and contingency plans mitigate seasonal disruptions.
Which Customization Options Are Available?
OEM/ODM services cover logo printing, packaging, color variations, and power output adjustments, with low MOQs starting at 200pcs. Prototype production typically completes in 7–14 days.
Shenzhen suppliers like Wecent can customize Qi2 and MagSafe designs, including firmware tweaks, delivering fully branded wireless chargers for private-label wholesalers. Portfolio reviews confirm the ability to execute multi-device and multi-coil designs effectively.
Why Prioritize Shenzhen Factories?
Shenzhen offers integrated component ecosystems, reducing costs by 30–50% and shortening lead times. GaN innovation thrives in this region.
Proximity to chips, coils, and R&D hubs enables rapid prototyping and continuous technological upgrades. Wecent leverages Shenzhen’s ecosystem for 15W–65W wireless solutions, minimizing IP risks and ensuring scalable production for B2B clients.
How to Evaluate Supplier Communication?
Fast response times under 2 hours, English proficiency, and dedicated account managers indicate operational efficiency. Transparent documentation and timely feedback are critical.
Testing response via RFQs and DFM inquiries predicts partnership success. Wecent consistently responds in under 1 hour, streamlining OEM projects and ensuring smooth B2B collaboration.
What Financial Stability Indicators Exist?
Look for suppliers with 10+ years of operation, audited financials, and high client retention to ensure long-term viability. Avoid debt-heavy or short-lived factories.
Wecent’s 15-year track record with 200+ global clients guarantees pricing stability and reliable service, providing assurance for large-scale wholesale commitments.
