A power bank is a portable electronic device designed to store electrical energy and recharge other mobile devices such as smartphones, tablets, or other USB-powered gadgets. It typically consists of a lithium-ion battery, input/output ports, and a circuit to manage the charging process. Users can charge the power bank in advance and carry it on the go, providing a convenient and portable solution to extend the battery life of their devices when access to traditional power sources is limited.
