I would not recommend this product. Power up spikes to about 25 V, takes about 400ms to regulate. Power down spikes to about 20V for about 100ms. Regulation when input is about 3.4V is nonexistent, oscillates or goes to about 27V. This would damage anything connected to it needing a regulated supply. Output was set to 5V and I varied the input from 4.5V to 3.4V. Put an oscilloscope on the output and was very disappointed. Current with no load varied from 8 to 12 ma. Put a 12ma load on it,

Start at Abluft 3.2volts. Always Step up so sou cannot Input 12v down to 5v. So aß descrbed Step up At lowest thank about 3.2V teh Output dann Raise and changes in and direction unpredictabke. I measures suddenly 20v instead 5volts which were adjusted. So dangerious if battery voltage for input goes too low But valuable device
