Pingxiang Chengpin Technology Co., Ltd. manufactures custom wireless charging induction coils using 99.99% pure electrolytic copper with Litz wire construction to reduce skin effect losses at frequencies above 100 kHz. The coils are designed for Qi-compatible devices, wearables, and industrial charging pads, with form factors customizable to fit tight enclosures. No standard dimensions or power ratings are listed, but the product is engineered for efficiency in low to medium power applications up to 15 W.
Litz wire construction consists of multiple individually insulated thin strands, reducing AC resistance compared to solid wire. The coils are available in rigid PCB-based or flexible printed circuit forms, with ferrite backing for magnetic flux concentration. Typical inductance ranges from 5 µH to 15 µH, and Q-factors exceed 80 at 100 kHz under standard test conditions. These are not off-the-shelf components but custom-engineered for specific device geometries and power requirements.
Buyers include manufacturers of smartphones, smartwatches, electric toothbrushes, and EV accessory chargers. The coils integrate into receiver modules and are often paired with rectifier circuits. Packaging is designed for anti-static and moisture protection during transit. Trade terms are not listed; buyers must request MOQ, lead time, and incoterms directly. No certifications are stated, so compliance with IEC 62368-1 or Qi certification must be confirmed per order.

Pingxiang Chengpin Technology Co., Ltd. is based in the Zhoujiang Electronic Information Industry Park, Pingxiang City, Jiangxi Province, China. The company is listed with harbor trust tier, indicating verified export activity. No details on years in business, workforce size, or production capacity are provided. The listing confirms custom coil design and manufacturing capability but does not state ISO certification, in-house testing labs, or client references.
The supplier has no recorded response rate or average response time, suggesting limited buyer communication. Buyers must initiate detailed technical discussions with clear specifications. No website, certifications, or quality system details are disclosed. This supplier is best approached as a contract manufacturer requiring full design input, not as a distributor of standard parts.
Our Custom Wireless Charging Induction Coil is engineered for high-efficiency power transfer in smartphones, wearables, and industrial wireless charging pads. Made from high-purity electrolytic copper with Litz wire construction, it minimizes skin effect and resistance at high frequencies. These coils support Qi and proprietary protocols, making them ideal for B2B buyers sourcing components for consumer electronics and EV charging infrastructure. Available in custom dimensions with flexible or rigid form factors, packed for safe international transit.

Verify the coil’s inductance, Q-factor, and resonant frequency with the supplier before ordering. Request measured performance data under your intended load and air gap conditions. Confirm that the ferrite material and Litz construction match your efficiency targets. Do not assume compliance with Qi or IEC standards without documented test reports from the manufacturer.
Lead time for custom coils is typically 20 to 35 days after design approval. Incoterms such as FOB Nanchang or CIF Shanghai are common. Payment terms are often 50% advance, 50% before shipment. Packaging includes anti-static bags, foam padding, and moisture-barrier cartons. Buyers must specify export packaging requirements, especially for long sea voyages or humid climates.
Perform incoming inspection for coil continuity, insulation integrity, and ferrite bond strength. Use an LCR meter to validate inductance and Q-factor against the supplier’s test report. Check for any physical deformation or strand damage in the Litz wire. Retain samples for reference and request batch-level documentation, including material certificates and test logs, before final payment.
