What is Wireless Charging?

Goodbye cables! Wireless charging provides consumers with newfound flexibility by eliminating cords and cables from the charging process and creating spatial freedom to charge multiple devices at once. Wireless charging can be used for next-generation devices in consumer, infrastructure, municipal, and industrial applications.

Semtech’s LinkCharge® wireless charging platform supports a broad range of device power levels: low (<5), medium (5W-15W) and high (>15W). Our out-of-the-box-ready infrastructure can be used in essentially any environment, providing wireless charging to standards-compliant and proprietary mobile phones and tablets.
