charger

A charger is an essential electronic device used to replenish the energy in batteries, most commonly for smartphones, laptops, tablets, and other portable gadgets. It works by converting electrical energy from a power source—such as a wall outlet or USB port—into a form suitable for the device’s battery. Chargers come in various types and power ratings, including wired and wireless options. Modern chargers often feature fast-charging technologies that significantly reduce the time needed to power up a device. With the growing demand for mobility and connectivity, chargers have become a crucial accessory in everyday life.
