Open source 12V powerbank
A custom 12V powerbank for Cube i7 Stylus from Muxtronics: Why would anyone even try to build a power bank – i.e. an external battery for charging mobile devices – these days? These things are commodity, it’s impossible to compete. Right? Well, that is until you find out that...
