PARAMETER --- Input voltage range DC 6V-32V; Output voltage DC 1.5V-32V; Max output current 5A, recommend use of within 4.5A; Max output power 75W, recommend use of within 50W. GENERAL USE --- As ordinary step-down module with over-current protection; As constant current LED driver module; DIY a solar power controller, etc. DISPLAY --- Large clear digital LCD display voltage & current value simultaneously. FEATURES --- Constant current/voltage mode; Voltage calibration & current calibration; USB interface; Protective case; Short-circuit protection; Over-temperature protection; Input reverse connection protection. NOTE --- 1). Output voltage is set as around 20V by default, if your input is lower than that, please turn potentiometer anticlockwise for 10 laps or more until voltage changes. 2). The case is packaged unassembled to avoid damage during transit. It needs to be manually installed. 3). Please carefully read the userโ€™s manual, especially the โ€œCautionsโ€ before using. You can find the PDF Instructions on this page -- Product information -- Product guides and documents -- User Manual [PDF].

Works and is great value

This is a buck converter that reduces DC voltage. If you need a specific output voltage, the input voltage needs to be about 1.5-2 volts higher than the desired output voltage. It has a nice makeshift "body" worth having. It's great because you can limit voltage, current, or both. This has confused people in some of the other reviews but is actually an advantage. If the current limit is too low for your minimum, it won't spend what you need. To use it you need to put a minimum load on it andโ€ฆ

Cons
  • Questionable purchase for the elderly

The DROK buck converter could damage your equipment

This little device is quite simple in design, but it has critical flaws in the following areas: 1) Voltage and current regulation (by powering the Input while holding the SET button) does not always allow calibration. You may have to turn the device on and off several times before the SET and ENT buttons increase/decrease the voltage or current accordingly. 2) There is absolutely no way to adjust the output voltage. You read that right. The board *has* voltage and current potentiometers, butโ€ฆ

Cons
  • I don't remember, but something happened

Excellent product works as expected - instructions are vague

This buck converter module was purchased for use in a project. It arrived quickly and looked good, but for some reason I can't calibrate the current. I've followed the instructions in the item descriptions (and also downloaded the user manual) and I'm still unable to perform the current calibration. Maybe because I'm using the USB port? No idea. The voltage is perfectly calibrated, everything else works perfectly. I'm not sure if I have a bad block or if I'm doing something wrong. It's supposed

Cons
  • Low repairability
