Describe:

100% new and high quality

Color: see picture

Size:4.4*1.9CM

Package Includes:1Set Charging Module with Cable

This module has three input voltages 6V/9V/12V, corresponding to the working voltage (nominal voltage) of the solar panel 6V/9V/12V respectively.

This MPPT solar charger enables you to get as much power as possible from a solar panel or other photovoltaic device into a rechargeable lithium battery.

Product Features:

Input voltage: select the corresponding module according to the nominal voltage of the solar panel (6/9V/12V)

Output voltage: nominal 3.7V full end voltage 4.2V lithium battery

Working ambient temperature: -40°C+85°C

When the current output capability of the input power supply is reduced, the internal circuit of CN3791 can automatically track the maximum power point of the solar panel and the charging current can reach 2A

PWM switching frequency: 300KHz Constant voltage charging voltage: 4.2V ± 1%

Constant current charging current set by external resistor for slip current charging of deeply discharged batteries

The product has automatic recharging function, soft start function

When charging, the CH light (red light) will be always on, and the OK light will be off (blue light): When fully charged, the CH light will flash, and the OK light will be always on

Note:

1. Please allow 5-10mm differences due to manual measurement, thanks.

2. The actual color of the product may be slightly different from the picture, and the website is caused by various factors such as the brightness of the monitor and the brightness of the light.
