GabrielVii Wrote 2419 days ago. build feels solid and hooked up with RC 3S lipo tested to power up laptop, feels warm after 15min running input voltage at 11.4v while output 19.23V @ ~1.1A with laptop under idle, unable to test load due to my multimeter unable to properly read current draw..... second & third pic show size comparison to old 5A boost regulator that failed after 3 months usage

By pe1osq 18/08/2015 I used this module to build a variable power supply. I use an input voltage of 12 volts (from a computer power supply) and need this module to create a variable (settable via the potmeter) output voltage ca 1 - 30 volt. With output voltages over 12 volts everything works fine. In the step down mode (voltages below 12 volt) the output voltage is not stable. For instance if I set the output voltage to 5 volts and apply no or very little load, then the outputvoltage "swings" between 4.8 and 5.3 volt.
By ArturKrajewski 24/05/2020 Great product. I used it to build a bench power supply with 2 variable channels and it works fine.
