    purchased to boost the power of mobile Bluetooth speakers with two 18650s, connect multimeter to Vin+/Vin- Then turn the small screw to display the desired volage, the module is very small and takes few places.

    This is the module powering my DSO Shell oscilloscope at about 9.5V from an 18650 cell. It shows about 10-15mV ripple at around 10kHz(?).

    If anyone has any problems with these boost converters most of the time they're not broken you just have to turn the trim pot up to 20 times in the anticlockwise direction until the voltage starts to climb. I thought all of mine were dead until I did that. Apart from that they're good value little modules.
