Wireless charging built for real products
Qi, Qi2, TX & RX solutions, ready to integrate.
CowinLink develops finished wireless chargers and custom transmitter and receiver hardware for OEM/ODM projects. We support the electrical, coil, firmware and product-integration work needed to move from an idea to a production-ready design.
Three ways to build with CowinLink
Start with a product, a module or a requirement.
Use an existing platform to shorten development or ask us to adapt the circuit, coil, enclosure and firmware around your device.
Finished Wireless Chargers
Charging pads, stands, foldable multi-device chargers and automotive products for private-label and OEM programs.
Browse finished products →TX Transmitter Solutions
Qi and Qi2 transmitter PCBAs, coils and firmware for embedded, automotive and purpose-built charging products.
Explore TX modules →RX Receiver Solutions
Compact receiver modules and custom coil designs for devices that need sealed, cable-free or repeatable charging.
Explore RX modules →Applications beyond the phone
Wireless power across products and industries.
Qi/Qi2 fits interoperable near-field charging. Custom inductive systems can be designed for dedicated devices, docks and operating environments.
A defined engineering path
From the first drawing to a production build.
Project deliverables are agreed at the start, including the files, samples, test work and production support your team needs.
Selected starting platforms
Hardware to begin the conversation.
These products cover finished chargers and both sides of the wireless-power link. Specifications can be adapted to the final application.
Built for product-development teams
Engineering detail matters before the industrial design is locked.
Coil position, metal, magnets, air gap, heat paths and surrounding electronics all affect wireless charging performance. Early integration work reduces avoidable redesign later.
Have a device, drawing or target specification?
Send the application, available space, input source and required receiver power. We will help identify a suitable TX, RX or finished-product route.
