DROK DC-DC Adjustable Buck Voltage Converter Stabilizer 6-32V to 1.25-32V LCD Display Constant Volt Amp 6V 12V 24V Step Down Voltage Regulator Power Module with USB Port Protective Shell

Nice little buck converter. Works as expected and it has been in service for over a month now. Of note, the current adjustment only works when the input current is continuous at a stable level. Since my application uses a solar panel for input power this is not possible. The LEDs are a nice addition and the display appears to be accurate. I like that it has the clear plastic case as well.

Works as advertised so far. All you have to do is put together the case.Rated at 75watts but the instructions recommend adding a cooling fan for use over 35 watts.Most of the concerns on negative reviews are covered in the troubleshooting and instructions provided.The display illumination can be turned on and off.For lower voltage use you have to turn the potentiometer screws back at least 10 turns or so before you will begin to see adjustments happen. You have to short the outputs to adjust amperage.The adjustment offered is very fine so you can get it bang on where you want it.I do not intend to use the USB as it warns you that it’s output is adjustable beyond 5 volts and can fry things.Bench tested it with a 9 volt battery.My intended use is to power outdoor LED lighting from a 12 volt battery source.

I needed a power regulator for an FPV setup in my RC car. No soldering required I was able to connect the battery lead to the screw down terminals selected the voltage in a safe range required by the DJI 03 Air Unit and hit enter. I am a novice with electronics so it was nice to feel confident that this plug n play regulator was installed safely and easily. I 3d printed a case for it with lots of ventilation and it looks cool strapped to the truck.

I have gotten into working with Arduino controllers and with that, I have acquired various power supplies over time. I needed something to be rather portable and allow me to adjust as I deem necessary.... this was simple to put together and all of the holes lined up right on the money. I used a 12v power supply from a bar code scanner and everything works great. What works for me is that I use the 12v side for some sensors that require that voltage and then use the other side of this for the stepped down voltage.And to say it does have a built in volt meter and amp meter plus it can toggle between in and out voltages... I am happy with the purchase. I have not scoped the output as for me it really doesn't matter yet!

The DROK Buck Converter is a compact unit with LCD display. It has three LED displays showing charging, full charge and constant current charging.I am using it to charge a 6V, 6AH LiFePO4 lantern battery from a 12V solar power pack that has 12V, 30AH LiFePO4 battery that is charged from a 120W solar panel through a charge controller.The DROK Buck Converter has good range to adjust input and output voltages. I liked its ability to adjust constant current output for charging batteries. Though it is rated at 5Amp, it cannot be used beyond 3Amp without the external cooling.IMPROVEMENTS RECOMMEND:1. The wire connectors +ve and -ve on both INPUT and OUTPUT side are too close to each other that can cause short circuiting. A larger terminal blocks (wire connectors) are recommended. The unit size may increase slightly but it is worthwhile to make this improvement.The heat sink on power supply chip is too small that is why it’s rated at 3Amp. If a larger heat sink is used the unit can handle 5Amp without needing any external cooling. It may require increasing the size of PCB but the unit is really small and increasing it size is worthwhile that will improve its utility.
