Product Description
27mm Qi Watch Coil Wireless Charging Coil
This 27mm Qi standard wireless charging coil is specifically designed for smart wearable devices such as smartwatches, integrating ferrite magnets and isolation sheets. The coil utilizes high-precision winding technology, complies with Qi protocol standards, and delivers stable low-power output suitable for watches.
Key Functional Benefits
Core Energy Transmission
- Wireless Power Supply: Compliant with Qi standards for safe, stable energy transmission to smartwatches and compatible devices through electromagnetic induction without physical connections
- Efficient Energy Conversion: Integrated ferrite magnets efficiently gather magnetic fields, guide magnetic flux lines, significantly improve charging efficiency, increase effective transmission distance, and reduce energy dissipation and heat generation
Safety and Stability Assurance
- Electromagnetic Shielding and Interference Isolation: Ferrite magnetic sheets and isolation sheets work together to absorb and shield excess electromagnetic fields, preventing interference with precision electronic components and external metal objects
- Electrical Insulation and Physical Protection: Isolation sheets provide reliable electrical insulation to prevent short circuits and offer mechanical protection and fixed support
Design and Adaptation Features
- Miniaturization and Precision Integration: 27mm diameter standard size tailored for compact devices with highly integrated module design for easy embedding into small devices or charging bases
- Magnetic Positioning Assistance: Works with internal watch magnets for precise automatic alignment using magnetic attraction, enhancing user convenience
