Product Features
● Efficient charging: three coils work together to produce a more complex and uniform magnetic field, effectively improving the charging efficiency.
● Fault-tolerant: multiple coils can be adapted to different charging distances and angles, the device being charged does not need to be accurately aligned with the charging area
● High degree of integration: integrated on the PCBA circuit board, closely matched with other circuit components.
● Good compatibility: As part of the PCBA circuit board, it is easy to integrate with the charging system of various electronic devices.
● Optimize the use of space: the integration of three coils on the circuit board can achieve a more powerful charging function in a limited space.
Product Advantages
● Free-Position Charging: Three-coil design provides a wide charging area without precise phone alignment.
● Stable & Efficient Charging: Flat copper wire, multi-layer winding and ferrite shielding improve power transfer and reduce energy loss.
● Low Heat & Reliable Performance: Low-resistance coils and magnetic shielding help reduce heat, ideal for enclosed installation in cars and furniture.
● Easy Integration: Coil array, drive circuit and control are integrated on one PCBA, with a plug-in connector for quick installation.
● 12V & 24V Compatible: Supports both 12V and 24V DC systems for passenger cars, trucks, buses and other vehicles.
● B2B Customization: Custom coil design, wire, connector, lead length and power output available based on project requirements.
● Quality & Compliance: RoHS compliant, CE certified, and manufactured under an ISO 9001:2015 quality management system.
