    Powering Raspberry Pi as a print server
  

*by A***N on Reviewed in India on 11 June 2019*

Fast delivery, good packaging and works like a charm!!👍👍 Lowest voltage attainable was ~1.5V. I used this buck converter to get a 5V supply from a 30V source inside a HP printer. 5V was needed to power up a Raspberry Pi WiFi print server which could be fitted inside the printer cavity to convert this non WiFi printer to a WiFi one. Initially the buck converter gave out 1.5V then after few clockwise turns of the adjustment screw it started putting out 5.1V which was perfect. It didn't load the printer power supply significantly at all.

    Works fine
  

*by D***U on Reviewed in India on 8 June 2021*

The voltage adjuster needs to be more smooth in operation. I used to step down my laptop charger voltage from 20v to 14v to charge bike battery.Initially it was pain to set the output voltage . It charged in 9 hrs with 1A o/p.
