The maximum allowed load power is 15W. The parameters of each version are as follows:
5V Version : Input 5-5.5V,Output 5V/3A
6V Version : Input 6-6.5V,Output 6V/2.6A
9V Version : Input 9-10V,Output 9V/1.7A
12V Version : Input 12-13V,Output 12V/1.3A
15V Version : Input 15-16V,Output 15V/1A
24V Version : Input 24-25V,Output 24V/0.5A

NOTE: Because the input and output ends are isolated by Schottky diodes, there is a voltage difference of 0.2-0.6V


Working Principle:
1 Input port input voltage, output port output voltage (Vout=Vin-0.2~0.6V)
2 If the battery is not fully charged, recharge the battery.
3 If the input port voltage disappears, the battery is discharged, and the voltage is boosted and output from the output port.
