Thin Square Base Hollow Circular WPT Coil, Custom Wireless Charging Induction Coil For Smart Watch & Wearable Gadget

Engineered for compact wearable electronics, our hollow circular charging coil is mounted on a square ferrite base. The slim profile minimizes overall product thickness, ideal for smart watches, earbud charging cases and portable health monitoring devices. We support customized coil inner/outer diameter, wire length and inductance parameters to match limited internal space of mini consumer products. Small batch samples are available for prototype verification.
