Li-ion Battery Charger with Magnetic Connector

by duthienkt

This is a simple, low-cost, and convenient charger. All plastic parts can be 3D printed, including the magnetic connector. Components include: * 1 mini Type-C power bank charging circuit * 2 electrical wires with an outer diameter of 1.8mm * 2 magnets with a diameter of 5mm and thickness >4mm * 2 screws 2mm*6mm Additional version for TP4056(Type C) * TP4056(Type C) * 2 electrical wires with an outer diameter of 1.8mm * 2 magnets with a diameter of 5mm and thickness >4mm This version omits the 5V output and functions solely as a charger — I will add that feature later. If you have any specific requirements for the magnet or wire sizes, feel free to leave a comment below.
