POWERBANK

A power bank, also known as a portable charger or external battery pack, is a portable device designed to store electrical energy and later release it to charge or power electronic devices. Here is a description of the key components and functions of a typical power bank:

1. Battery Cells: The core of a power bank is its battery cells. These cells store electrical energy and determine the power bank’s capacity, which is typically measured in milliampere-hours (mAh) or watt-hours (Wh). Power banks may use various types of battery cells, such as lithium-ion or lithium-polymer, depending on the model and capacity.

2. Input Port: The input port is used to recharge the power bank itself. It typically features a USB Type-C, Micro-USB, or Lightning connector, allowing you to connect the power bank to a charger or computer for recharging.

3. Output Ports: Power banks have one or more output ports where you can connect your electronic devices using USB cables. These ports may vary in terms of charging speed (e.g., standard USB, USB-A, USB-C) and compatibility with different devices.
