Charger

A charger is a device used to supply electrical energy to recharge batteries. It converts electrical power from an outlet into a format that can be used to replenish the charge in batteries, such as those found in phones, laptops, and other portable electronic devices. Chargers can vary in design, size, and functionality, typically consisting of a power plug, a transformer, and a connector for the battery or device being charged. In broader contexts, the term "charger" can also refer to a type of large plate for serving food or a horse trained for battle or sport; however, in the context of electronics, it primarily denotes the device used for battery charging.
