The power bank 4000 project is a power bank that uses a 4Ah Lipo cell and a charge/discharge circuit. Besides the main component: the LiPo charger there are other components: n.2 usb breakout n.1 power switch I designed the 3D case using a parametric open-source software: openScad that is particularly suitable for projects like this.
