Charging indicator light description
The module can roughly judge the working status of the module through the two LED lights and other status. CHRG
It's red, stdby is blue. When the battery is charging, the red light is highlighted and the blue light is on.
Not on, but the red light is slightly brighter. If there is a boost output
Depending on the output power, the red light may be highlighted during charging but not connected.
When there is no load, the blue light is on and the red light is dimly on.

Note:
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2cm measuring deviation due to manual measurement.
