Such Power Banks are great to have around to quickly charge up your big electronics like a laptop or tablet and they are also very useful when powering more current demanding electronics projects. That is why I properly tested a PCB from Aliexpress which allows us to create such a DIY Power Bank easily. And at the end we will see whether you should try such a DIY solution or rather stick to the Buy version. Let's get started!
