Comprehensive Guide to Chargers

1. Core Definition

A “Charger” (formally called a charging device) is an electronic accessory designed to supply electrical power to rechargeable devices such as smartphones, laptops, tablets, wearables, and other portable electronics. Its primary function is to convert AC (alternating current) from wall outlets into DC (direct current) compatible with the target device, or to transfer power from one device to another (e.g., power banks). Chargers vary in power output, port types, and compatibility, and are essential for maintaining device usability.
