An EV charger is a device that supplies electrical power to recharge electric vehicles (EVs). There are various types, including home chargers, public charging stations, and workplace chargers. They come in different power outputs, such as slow (up to 3kW), fast (7-22kW), and rapid (50kW and above), which affect charging time and suitability for different vehicles. Most residential users opt for fast chargers, while rapid chargers are found in public areas for quick top-ups.
