Power Bank

A power bank, also known as a portable charger, is a rechargeable battery pack that can be used to charge mobile devices such as smartphones, tablets, and other gadgets. It’s a convenient device, especially when you’re on the go and don’t have access to a wall outlet.

Power banks typically come with a USB port and a charging cable. To use a power bank, you simply connect your device to the power bank’s USB port using a compatible charging cable. The power bank will then provide power to your device, allowing you to charge it on the go.

Power banks are available in various capacities, measured in milliampere-hours (mAh). A higher capacity power bank can charge your device multiple times before needing to be recharged itself. When choosing a power bank, consider the capacity and the number of USB ports it offers.
