[0002] A power adapter, also known as a charger or power supply, is an electronic device whose primary function is to convert alternating current (AC, such as the electricity from your home grid) into direct current (DC) for use by electronic devices. Power adapters are essential because most modern electronic devices, such as mobile phones, laptops, tablets, and digital cameras, use DC power to operate their internal circuits. A power adapter typically includes an input terminal, a rectifier, a transformer, a filter, and an output terminal.
