WIRELESS CHARGER A wireless charger is a device that allows you to charge your electronic device without using cables. It uses the principle of electromagnetic induction to transfer energy from the charger to the device being charged. The charger consists of a base station that is connected to a power source and a charging pad that is placed on top of the base station. The charging pad contains a coil that generates an electromagnetic field, which induces an electrical current in a compatible device placed on the pad. The current is then converted into a usable form of energy that charges the device's battery. Wireless chargers are commonly used to charge smartphones, smartwatches, and other portable electronic devices.
