Frequently Asked Questions
Everything you need to know about our wireless charging solutions, OEM services, and retail-ready programs
We focus on three product families designed for retail channels:
3‑in‑1 magnetic charging stations (phone + watch + earbuds), e.g., YF‑3 with Qi2.2‑compatible magnetic alignment and up to 25W output.
6‑in‑1 foldable chargers (3 wireless pads + USB‑A & Type‑C wired outputs), e.g., YF‑6, which folds to 19 mm for travel retail.
Single‑device pads, desktop stands, and multi‑device docks.
Every product is designed with real shelf demand in mind, not just technical specs. Custom ODM development is also available.
Yet we keep creating new models for the growing markets demand.
Yes – full brand customization is our core. We cover:
Logo application: pad printing, laser engraving, or silicone embossing.
Colour matching: we match your Pantone codes for the housing, cable, and packaging.
Retail packaging design: custom box structure, insert, user manual, barcode (UPC/EAN), and QR code.
Firmware tweaks: LED behaviour, auto‑wake, or custom welcome patterns (optional).
Logo placement proofs are delivered within 5 business days of receiving your artwork, and a pre‑production sample is shipped for final approval before mass production.
Every standard product ships pre‑certified to simplify your market entry:
CE (EU requirement)
FCC (US standard)
RoHS (hazardous substance restriction)
Qi / Qi2 compliance where applicable (interoperability & magnetic power profile)
Certificates and test reports are included with each shipment as PDF files. We can also assist with UL, ETL, or other region‑specific certifications if your order volume justifies it.
We keep MOQ flexible to match your launch plan, typically it depends on the product type and customization requirements.
Standard products usually support lower MOQ, while OEM and custom packaging projects may require higher quantities.
Please contact us for project-specific details.
Timelines are stable and predictable:
Standard product + logo: 15-20 days after sample approval.
Custom packaging & color: 20-30 days.
New ODM development: engineering samples in 30-45 days, then mass production lead time as above.
Shipping from Shenzhen to US/EU main ports typically takes 8–15 days by air and 25–35 days by sea. We reserve capacity for repeat partners to avoid delays during Q4 peak.
Yes, we offer three sample tracks:
Stock sample (no customization): dispatch within 2–3 working days.
Custom sample (with your logo/color): produced in 7–10 days, then shipped.
ODM engineering sample: built after design freeze, timeline depends on project complexity.
Sample fees (if any) are typically refunded against your first production order. Shipping cost is borne by the buyer.
Every unit includes multi‑layer hardware‑level protection:
Over‑temperature protection (auto‑throttles power when temperature exceeds safe limit).
Over‑voltage / over‑current protection.
Foreign object detection (FOD) – stops charging if metal objects (keys, coins) are placed on the pad.
Short‑circuit protection.
These are engineered into the PCB design and verified during QC, not added as an afterthought.
Yes.
Our wireless charging products are designed to support a wide range of compatible devices based on Qi or magnetic charging standards.
Compatibility may include major smartphone brands and wireless charging-enabled devices.
Absolutely. Our ODM process covers:
Industrial design and mechanical engineering.
PCB layout, antenna tuning, and coil optimization for charging efficiency and thermal management.
Prototyping (EVT/DVT) and design‑verification testing.
Certification assistance (CE, FCC, Qi) for the new design.
We’ve taken projects from a napkin sketch to a shelf‑ready product in under 90 days, depending on complexity.
We manufacture the full retail unboxing experience:
Custom‑printed colour boxes (matte/gloss lamination, window cut‑outs, spot UV).
Inserts – moulded pulp, plastic tray, or die‑cut EVA foam.
User manual, warranty card, and brand story booklet in your language.
Barcode (UPC/EAN) and QR code directly printed on the box.
Export master carton with shipping marks and palletization if needed.
All packaging is designed to survive long‑haul freight while looking premium on shelf.
We implement a three‑stage QC protocol:
IQC (Incoming): inspection of all components (PCBs, coils, housings, cables) before assembly.
IPQC (In‑process): line checks every two hours, plus 100% functional testing of each unit on the line.
OQC (Outgoing): random sampling per AQL 2.5 Level II; each shipment includes a QC inspection report upon request.
For repeat orders, we assign dedicated production lines and maintain batch traceability via date codes.
We mainly support clients targeting:
- US markets
- EU markets
- eCommerce brands
- Retail chains
- Promotional product distributors
Our solutions are developed with international market requirements in mind.
Warranty: 12 months from shipment date against manufacturing defects.
Defect rate allowance: standard allowance is ≤1%. For batches exceeding this, we provide replacements, credit, or a rework arrangement.
After‑sales: we offer remote technical support to your customer‑service team. If a systemic issue arises, we’ll dispatch a quick corrective action report and implement changes to prevent recurrence.
Qi2 is the next‑generation wireless charging standard by the Wireless Power Consortium. It introduces a magnetic power profile based on Apple’s MagSafe technology. Key advantages:
Perfect magnetic alignment every time, eliminating misplacement that causes slow or failed charging.
Consistent 15W fast charging for iPhones and future Android devices adopting the standard.
Better thermal management through precise coil positioning.
Our YF‑3 model is designed to be Qi2‑compatible, giving your retail brand a strong selling point as the market shifts to Qi2.
We take IP protection seriously:
A mutual NDA can be signed before any detailed project discussion.
For custom ODM designs, the mould ownership is transferred to you in writing after payment.
We offer exclusivity agreements for custom formulations (colors, materials) and proprietary packaging designs.
Your buyer list and pricing are never shared with other clients.
Like what we’ve been doing all the time, every model is wholly and privately developed by ourselves and fully patented.
Yes, we support your sales channels with:
High‑resolution white‑background product images and lifestyle shots.
3D renders and exploded‑view diagrams.
Ready‑to‑download spec sheets (PDF) with full specifications and certification logos.
Basic video footage clips (on request).
These assets are provided free of charge for your active products, helping you list faster and sell more.
OEM services focus on customizing existing products with your branding and packaging.
ODM services may involve additional product design modifications or customized development based on project requirements.
We focus on providing retail-ready wireless charging solutions that combine:
- Product functionality
- Customization flexibility
- Packaging support
- OEM/ODM capability
- International market experience
Our goal is to help clients launch reliable and market-ready wireless charging products efficiently.
