The default output is about 9V, please debug before use
Input voltage 4.5-8V
The output voltage is continuously adjustable from 4.3 to 27V (more than 4.3V and less than 27V, any voltage can be output, and the voltage can be adjusted counterclockwise by self-adjusting)
Charging voltage 4.2V
Charging current: 1A max
Discharge current: 2A max
Output current: 5V 1.4A, 9V 0.8A, 2V 0.6A
Quiescent current is about 0.5 mA
Overshoot protection: Yes
Over-discharge protection: None (2V cuts off the boost but does not block the output, the output is 2V)
For example, the VIN+ terminal is connected to a 5V solar panel and the BAT+ terminal can output 4.2V to charge a 3.7V 18650 battery.
The OUT+ terminal can output an adjustable voltage.
Can be used to recharge the lithium battery of a multimeter
