KingARC's technical library covers Qi2 MPP, EPP, BPP, Samsung PPDE, Apple-compatible and Google-compatible protocols. The reference designs serve phone chargers, watch chargers, in-vehicle chargers, magnetic power banks and multi-device charging stations. Each page provides chipset, compatibility, coil and PCB data, input conditions, performance and protection details for engineering evaluation.
Based on target power, device protocols, mechanical space, power input and destination-market certification, we can support module selection, PCB and coil adaptation, firmware tuning, thermal optimization, EMC improvement and OEM/ODM development from prototype to mass production.
The library includes Qi2 MPP, EPP, BPP, Samsung PPDE, Apple-compatible, Google-compatible and AP/SAM watch charging solutions from 1.5W to 25W. Protocol support varies by module and is listed on each specification page.
Yes. We can adapt the chipset, coil, PCB layout, firmware, input interface, thermal strategy and mechanical structure for phone chargers, car chargers, magnetic power banks, watch chargers and multi-device charging stations.
Please provide the target devices and protocols, required wireless power, input voltage, available PCB and coil space, product structure, certification market, estimated volume and development schedule. We can then recommend a suitable module and development path.
