Well, I don’t know, it needs to be a whole study. I was specifically interested in the question of how the module holds voltage. The goal is to replace the expensive Krona in measuring instruments with a pair of ordinary finger batteries. Look on the Internet, there will probably be something there.

And efficiency = what?
And what is the output? What kind of interference? What can be connected except for a bulb?

The package arrived pretty quickly. The SX1308 module made me happy. Gathered a small stand for verification. I applied 3 V to the input, set 12 V at the output with a trimming resistor. The output was loaded with a 220 Ohm 2 W resistor. The voltage did not subside. He smoothly raised the input voltage to 10 V, the output voltage increased by only 0.08 Volts. A very good result for such a crumb! Ali Bastre, Stary Oskol, 15,11,2019
