OEM / ODM wireless power engineering

Custom Qi Wireless Charging TX & RX Solutions

From a transmitter module or receiver PCBA to a finished branded charger, CowinLink helps product teams turn wireless-power requirements into production-ready hardware.

Three ways to work with us

One engineering partner, from power transfer to product

Choose a proven platform for faster development or request a custom electrical, coil, firmware and mechanical design around your product.

TX

Transmitter solutions

Qi and Qi2 transmitter modules, coil assemblies and complete charging bases designed around your input, power, thermal and space constraints.

  • Single- or multi-coil architectures
  • FOD, thermal control and firmware tuning
  • USB-C, automotive and embedded power inputs
RX

Receiver solutions

Compact receiver PCBAs and custom coils for products that need cable-free charging, sealed enclosures or a purpose-built battery interface.

  • Thin, shaped and space-constrained coils
  • Battery, PMIC and system integration
  • Efficiency, heat and alignment optimization
OEM

Finished wireless chargers

Private-label charging pads, stands, foldable multi-device chargers and embedded products with industrial design and packaging support.

  • Housing, materials and branding options
  • Prototype through pilot production
  • Compliance and certification support

Engineering workflow

A practical path from requirements to mass production

The exact scope is agreed at project start, so your team knows which technical files, samples, tests and production outputs are included.

DefinePower, device, coil gap, enclosure, input, target market and volume.
DesignArchitecture, chipset, coil, schematic, PCB, firmware and mechanics.
ValidatePrototype testing for power, heat, FOD, alignment and interoperability.
QualifyEVT/DVT refinement plus EMC, safety and certification preparation.
ProducePilot build, fixtures, quality controls and volume manufacturing handoff.

Project deliverables

What your development team can receive

Electrical

Schematic, PCB/PCBA, coil specification and BOM as defined in the project scope.

Embedded

Firmware configuration, protection logic and system-interface support where applicable.

Validation

Performance, temperature, FOD, alignment and pre-compliance test records.

Production

Approved samples, assembly requirements, test methods and quality checkpoints.

Certification note: Qi or Qi2 certification applies to a specific final product and WPC registration. Certification status should be verified by product ID in the Wireless Power Consortium product database.

Starting points

Representative TX and RX platforms

These existing product pages can help define an initial direction. Parameters and certification requirements can be adapted to the final application.
