The Qi Standard is a universal standard for wireless charging technology, allowing devices to charge without the need for physical connectors. Developed by the Wireless Power Consortium, it enables compatible devices, such as smartphones and tablets, to charge simply by being placed on a charging pad. This technology uses electromagnetic fields to transfer energy between the charger and the device. Qi charging is designed to be safe and efficient, with built-in features to prevent overheating and overcharging. Many popular brands, including Apple and Samsung, have adopted the Qi Standard, making it widely available in various public spaces and homes, enhancing convenience for users.
