The technology that allows for the charging of devices without physical cables is known as wireless charging, often using inductive charging or resonant charging methods. Inductive charging works by transferring energy through electromagnetic fields between a charging pad and a compatible device. Devices that support this technology typically include smartphones, smartwatches, and other electronic gadgets. Wireless charging enhances convenience by eliminating the need for physical connectors and helps reduce wear and tear on ports. It is increasingly common in public spaces such as restaurants and airports.
