A wireless charger is a device that allows you to charge your electronic gadgets without using a physical cable. It works by using electromagnetic fields to transfer energy between the charger and the device. Most commonly, wireless chargers are used for smartphones, but they can also charge other devices like smartwatches and earbuds. To use a wireless charger, you simply place your compatible device on the charging pad. The charger then sends power to the device through a process called inductive charging. This technology is convenient because it reduces wear and tear on charging ports and eliminates the hassle of tangled cords.
