The use of mobile phones is increasing day by day due to the involvement of digital and online things in our lives. During the period of the pandemic, when offices and educational institutions were closed due to the risk of spreading Corona, everyone shifted their work to the online mode. In the online working, a large backup of battery is required to continue the work. Students and workers have to face the problem of insufficient battery in mobile phones when they do not have the access to electricity or an ordinary charger. The power bank gives them the facility of charging their mobile phones at any time especially when they do not have the charger. The users just need to charge their power bank at once and then they can charge their mobile phones without any interruption.

Creating a power bank on PCB is very simple but the task to send it to the manufacturer for fabrication is quite difficult for me. I avoid going to the manufacturer, so I have created my project online on Inventhub. Through Inventhub I can get connected to the manufacturer and component provider directly. This online platform gives me the facility of creating the Bill of Material (BOM) of my project that helps me to send my components list used in the project with exact parameters including value, footprint, and manufacturer.
