What Is Wireless Charging And How Does It Work?
Wireless charging is a technology that allows you to charge your device without the need for a physical cable. It works by transferring energy between a transmitter (the charging pad or base) and a receiver (the device to be charged) through an electromagnetic field. When the device is placed on the charging pad, the transmitter sends an alternating current (AC) through a coil, generating a magnetic field. The receiver in the device then converts this magnetic field back into an electrical current, which is used to charge the battery.
The technology used in most wireless charging pads and devices, including the S21, is called Qi (pronounced “chee”). Qi is an open standard developed by the Wireless Power Consortium, a group of companies that aim to promote wireless charging technology. The Qi standard ensures compatibility between different devices and charging pads, making it easy to find a compatible charger for your S21.
