Solar Power Manager (C) for 6-24V Solar Panel

This is a Solar Power Manager from Waveshare. The Power Manager supports panels from 6-24V, thus charging three 18650 Li-Ion batteries (not included) and provides a regulated 5V/3A output via either USB-A or USB-C. The battery can be charged via USB-C or the solar cell and can be used as a conventional power bank. With this power bank, you can also load a power bank with small currents goes into a sleep mode and the output voltage drops to 2.5V. 

WARNING: Li-Ion and Li-Po batteries can catch fire or even explode with careless use. Always check the polarity of the batteries, never use batteries from different manufacturers at the same time and keep out of the reach of children.
