A mini power supply made with the ZK-4KX module, 4 18650 (2P2S) for a total of 8.4V and about 5A, a power bank recycled PCB only for charging. The switch, connects all the batteries in parallel for charging and unconnects the module.
All the stuff is recycled. The power supply comes quite handy for me.
