The battery is a 18650 lithium-ion battery, and the charging board supports 5V/2.1A input and output. The PCB board has several components, including resistors, capacitors, and IC chips. We noticed that the PCB board had a protective film covering the circuit board, which is excellent for protecting the components from dust and moisture.
