This miniature USB power supply utilizes a 18650 Li-Io battery as its power source. It features a Mini USB port for charging and another USB port for discharging purposes. The electronic components are sourced from DX.com, where I chose a Li-Io charger and a USB power converter circuit board to cater to this specific application. DX part numbers: 144856 and 146765.
