Wireless Charging Coils, Ushering in A New Era of Convenient Charging

Wireless charging coils, ushering in a new era of convenient charging

In the context of rapidly advancing technology, wireless charging technology is gradually transforming our lifestyles, bringing tremendous convenience to the charging of various electronic devices. As an industry leader, Pingxiang Chengpin Technology Co., Ltd. has attracted much attention for its wireless charging coil products, leveraging its exceptional technical strength and rich production experience.

Excellent Quality Stems from Professional Manufacturing

Pingxiang Chengpin Technology Co., Ltd. boasts advanced production equipment and a professional technical team, dedicated to creating high-quality wireless charging coils. The company strictly controls every link in the production process—from raw material selection to the final product formation—with rigorous inspections at every stage. We insist on 100% reliability testing of raw materials to ensure that each wireless charging coil delivers outstanding performance and stable quality.

For example, in material selection, we use high-quality copper as the coil wire. Copper, with its excellent conductivity, effectively reduces resistance loss and improves charging efficiency. Additionally, based on different application scenarios and customer needs, we carefully select suitable shielding materials, such as ferrite and other magnetic shielding sheets. These shielding materials act like "traffic police" for magnetic field management, precisely directing magnetic fields to target devices, preventing scattered magnetic field diffusion, enhancing coil efficiency, and reducing the risk of overheating in surrounding metal objects.

Innovative Design to Meet Diverse Needs

The company's R&D team continuously explores innovations, delving into key specifications of wireless charging coils to meet the increasingly diverse market demands. In the design of wireless charging coils, parameters such as coil diameter, number of turns, and inductance are carefully considered and optimized.

In terms of coil diameter, we offer multiple specifications: from small coils of approximately 15mm for compact electronic devices like smartwatches and wireless earbuds, to 50mm diameter coils for larger equipment. Different diameters determine variations in magnetic field coverage, and we provide the most suitable solutions based on the actual needs of customers' devices.

In turn design, we understand its critical impact on inductance and magnetic field strength. Through extensive simulation tests and accumulated production experience, we have precisely found the balance between the number of turns and efficiency. For instance, for a Qi-standard transmitting coil, we carefully design the number of turns to be between 12-15, ensuring sufficient magnetic field strength and transmission distance while avoiding overheating caused by excessive turns.

As a key indicator of energy conversion, inductance is strictly controlled in accordance with Qi standards: the transmitting end inductance is maintained between 5-30μH, with the receiving end precisely matched. For coils supporting 15W fast charging, we set the inductance to approximately 10μH, balancing charging efficiency and stability.

Wide Applications Leading a Convenient Life

Pingxiang Chengpin Technology's wireless charging coils have extremely wide applications across numerous fields. In consumer electronics, whether smartphones, tablets, wireless earbuds, or smartwatches, our coils provide efficient and convenient charging solutions. Users simply place their devices on a wireless charging pad to start charging, freeing themselves from cumbersome cables and making charging simpler and more convenient.

In the automotive sector, our wireless charging coils also play an important role. Today, more and more cars are equipped with wireless charging functions, allowing drivers to conveniently charge their phones and other devices while driving, enhancing driving safety and convenience.

Furthermore, our wireless charging coils are widely used in smart homes, medical equipment, and industrial instruments. For example, in smart home systems, they power devices like smart cameras and speakers, keeping living environments neat and aesthetically pleasing. In medical equipment, wireless charging reduces cable connections, lowers infection risks, and improves usability.

In the future, Pingxiang Chengpin Technology Co., Ltd. will continue to uphold the spirit of innovation, continuously improve product quality and technical capabilities, provide customers with more high-quality and efficient wireless charging coil products, and contribute more to promoting the development and popularization of wireless charging technology.
