9v power bank
thingiverse
I wanted a power bank that could supply 9 volts to my DSO138 and component tester, so I coupled a TP4056 charger board and M140 step-up board together. This product was remixed from the website http://www.thingiverse.com/thing:1684850. It was created with Tinkercad and can be edited online at https://www.tinkercad.com/things/b2wxAGBoVvL.
