In this video we will be having a closer look at powerbanks and their one flaw. Now I do love powerbanks because they are the perfect portable power source for your electronics projects. They provide 5V, are super easy to handle, safe and cheap. Only problem is that they turn off automatically when there is only a small load attached which can be a problem for some of my projects. So in this video I will explore 4 solutions or “hacks” in order to get rid of this problem. Let’s get started!
