Portable Chargers, also known as power banks, are compact electronic devices designed to charge other portable electronics such as smartphones, tablets, e-readers, and laptops when conventional power sources are unavailable. They come in various capacities, measured in milliampere hours (mAh), to accommodate different charging needs. Smaller chargers with lower mAh ratings cater to devices like smartphones, while larger ones can charge multiple devices simultaneously or even laptops. Portable chargers may feature one or more USB ports for universal compatibility across various devices and often support fast-charging technologies. Some models include built-in cables or LED indicators displaying the remaining power. Overall, portable chargers provide a convenient and versatile solution to keep electronic devices powered on-the-go.
