Review: Compact solution to drop 24v to 12v/5v for my Noctua Upgrade - Worked great when upgrading the fans on my Ender 3 V2. Take time to dial in the required voltage correctly. Twin output is useful if running more than one fan off the Buck or in my case sending the 12v output off to a Micro USB buck to power a Raspberry Pi. It states an input voltage of 23v but working fine with the 24v input on my printer. All 5 working great, no duds.
Review: Nice small, reliable buck converters - Good value for money buck converters, had them running 24/7 and they output the correct voltage continuously when set with the potentiometer. Very small form factor would recommend.

### ⭐⭐⭐⭐⭐ Nice small, reliable buck converters
*by M***S on 11 June 2026*

Good value for money buck converters, had them running 24/7 and they output the correct voltage continuously when set with the potentiometer. Very small form factor would recommend.

### ⭐⭐⭐⭐⭐ Ideal to set down from 24 volts to 12 volts.
*by J***N on 11 February 2024*

Used one of these to reduce voltage from 24 volts to 12 volts on my 3d printer to run a different fan. Works well. It was also possible to find a 3d printed case on a well known website for stl files which worked perfectly. Good value for money.
