Wireless Charging

Understanding Wireless Charging Technology

Wireless charging, also known as inductive charging or Qi charging, relies on electromagnetic induction to transfer power from a charging pad or transmitter to a receiver coil embedded within a compatible device. When the charging pad is plugged into a power source, an alternating current (AC) is generated, creating a magnetic field around the transmitter coil. The receiver coil in the device picks up this magnetic field, inducing a current that is converted into usable power to charge the device’s battery. Wireless charging standards such as Qi (pronounced “chee”), developed by the Wireless Power Consortium (WPC), ensure interoperability and compatibility between different devices and chargers, enabling widespread adoption and seamless integration across various industries.
