4.0 out of 5 stars Very handy way to create a controlled voltage or amperage from a DC power source
Reviewed in the United States on February 12, 2024
Verified Purchase
I love the small panel mount housing. Makes very easy to install into an existing tool or create a housing around the small form factor. I wish it was faster to get to the voltage set point. I also wish they would make one that would carry more than 8 Amps. Still very useful tool for technicians in the automotive or electronics industry. Great price!

4.0 out of 5 stars Works Perfectly - Installed on Tesla Model 3 for secondary battery charger in trunk
Reviewed in the United States on December 14, 2023
Verified Purchase
Mobile Radio secondary LiFePo4 100ah battery, in the trunk, needed to drop source from 15.5VDC to 14VDC at 1amp. The DC-DC Converter/Charger worked perfectly. It is mounted inside a project box with adequate ventilation. Power source is a standard fused cigarette light plug. No signal distortion VHF/UHF. I have not tried HF yet.
The only weak point is the internal power plug. Max wire is #14. I used #14 red/black wire. If too much cable movement, the internal connector will come out. I may have to use Loctite Stik'n Seal to secure plug.
Hope this helps others.

5.0 out of 5 stars These DROK DC-DC converters work well for my DIY electronic projects.
Reviewed in the United States on September 18, 2023
Verified Purchase
I've been using DROK DC-DC converters for a while now. I have a bunch of Ryobi 18V tools/batteries and a couple of the 40V ones. I use the DROK DC buck/boost and buck converters to make adjustable DC power supplies to power various items (small guitar amplifiers, effects pedals....) so I don't have to plug into AC. I've purchased battery adaptors on Amazon for Ryobi 18V, Milwaukee 18V and Kobalt 24V. Some simple wiring, a small project box, a DROK converter and you can build a nice power supply.

I purchased this 0-55V buck converter to use with my 40V Ryobi batteries and made a 0-39VDC/0-8AMP power supply for my workbench and so far, it works great and the readings are very accurate when comparing the display with my DVOM.

Note: The photos show both the DROK 0-55VDC buck converter (w/Ryobi 40V battery) and the 0-30VDC buck/boost converter (w/Ryobi 18V battery).

Would recommend DROK products as I only had one the was inoperable (0-30V buck/boost - may have been user error when I desoldered the wiring terminals so I could hard wire to the PC board).

Takes a little getting used to when controlling the outputs. It sits on my work bench and is powered by solar panels. Great for powering electronic projects.

4.0 out of 5 stars This is a good product with a nice display
Reviewed in the United States on July 8, 2023
Verified Purchase
This is a good product, but wasn’t perfect for my application. (I needed a step-up converter with the same display and controls). Still this is easy to use and nicely done. Be aware the voltage drop between input and output will be several volts, typically about 3.5V minimum in my use.
