- 【Characteristics】 This Buck Converter is equipped with LCD Display, Acrylic Case and Heat Sink. LCD Screen can display input/output voltage, output current and output power. Voltage precision is 0.05V, current precision is 0.005A. Acrylic case can keep the converter board away from dust, which is protective. Heat Sink can keep module 120W for long-time using in a low temperature. If you want to reach maximum power 160W, please improve heat dissipation.
- 【Easy Operation】 A user manual will be included in package, which can help you easier to operate. The button can control ouput voltage ON/OFF status, and you can set the default output state is ON/OFF for the next time. The potentiometer can help you to adjust volt amp in a simple and fast way.
- 【Protection】 It has reverse-connect protection, short circuit protection and over current protection. When you connect the input wire reversely or short circuit, the module will not burn. And roate the CC potentiometer to set over current protection value you want.
- 【Application】 The volt conversion board can be used for 5v 6v 9v 12v 24V 30V 32V 3a 5a 10a devices, like solar panel, lab, experiment, RV, All-Terrain Vehicle, car, battery charger, LED stripes, etc.

- Reviewed in Canada on October 31, 2024Verified PurchaseI bought a USB-C trigger module and programmed it to output 20V, 5A. However, I needed more amps to heat 18AWG Nichrome wire to 300C.
This buck converter took the input of 20V, 5A (Measured with a Fluke 117 Multimeter) and outputted 5V, 12A consistently (also measured with the same multimeter).
I tweaked it later on to output 5V, 8A which is more than enough for my application. It works flawlessly.
A bit on the pricey side, but it is flawless.

- Reviewed in Canada on April 28, 2019Verified PurchaseThis is a great little device whether you're running it on the bench or fitting it in a project box. It is easy to assemble and looks and feels good too. Fitment of the heatsink is recommended. The simple controls and easy to read display indicating input and output voltages as well as current draw are helpful as well.
I ordered two of these and using my benchtop power supply and a volt meter I did find that the output voltage was 0.02 volts lower than what was indicated on the converters display but for the price and the equipment I'm powering off it I am not complaining.
If I were to have issues it would only be that one of the displays I had was scratched by one of the screws during shipping and that having either a display brightness controller or an option to turn the display off would be welcome. Also be careful about how tight the screws are when assembling as the clear plastic protectors can crack in the corners. Theses really are just super minor things that doesn't really take away from the operation of the device.
- Reviewed in Canada on May 18, 2023Verified PurchaseI like the LCD display. It comes handy when adjusing the right voltage and current that I need. I also prefer a higher current rating of 15 to 20 amps. It would be better if it's in a good close casing to prevent dust from accumulating which might cause short circuiting. I used it for my HHO generator.
- Reviewed in Canada on July 6, 2025Verified PurchaseThis was the second one I bought because the first one didn't work.. I'm pretty sure I was sent a pre assembled broken convertor. With no instructions. I think it was the broken one I previously returned
- Reviewed in Canada on May 5, 2025Verified Purchaseworks okay a long as the voltage stay at least 2 volt or high to maintain a lower out put voltage. the display back light is always on and to me that a deal breaker. I'm going to order " DC Step Down Converter, DROK Adjustable Buck Converter, Voltage Regulator 6V-32V 30V 24V 12V to 1.5-32V 5V 5A LCD Power Supply Volt Reducer Transformer Module Board with USB Port Protective Case " instead. I have had this for a very long time and you can shut off the backlight, it uses a little more amps but seem to maintain the voltage i need to be coming out at all times.
- Reviewed in Canada on June 16, 2022Verified PurchaseI am extremely happy with my purchase of this product. It was easy to assemble, came with accurate instructions and worked as advertised. It is truely remarkable, how technology has evolved over the years to produce a product like this for the low cost and excellant proformance this unit has.
Thank you...

- Reviewed in Canada on June 30, 2024Verified PurchaseNo load, the capacitor(s) in this unit draw a lot of current when you initial power on. I ended up buying some anti spark connectors for the supply side.

1.0 out of 5 stars Actual product sent was different than what's advertised.
Verified PurchaseThe seller sent a product that's similar but not the same as the listing.
It did not have any current control.
So it's only CV not CC. Which kind of defeated the whole purpose of buying it as there are several voltage adjustable modules for much cheaper price. Its adjusting the current output which makes this different from other modules.
Ended up returning the same minute. A total waste of time. Watch out before buying this.
Also, the voltage adjustment was not through trimpot (potentiometer), it was through +/- buttons, which again is not as listed.
