In today's video I am going to share an awesome idea about how to make a portable charger or a power bank as lots of people call it yourself at home. Let's call the DIY craft a mini tic tac power bank because all inside component will be fitted into a tic tac container. To make one yourself is pretty easy and simple. We will need only L 7805, a 9 volt krona battery, USB connector and connectors for krona batteries as well. Since a usual krona battery isn't enough I advise you to to use a maximum capacity krona battery you will only be able to find. Keep your fingers crossed!
