Exactly what I needed for my project! The wires are nice tinned copper and the jackets are silicone. I did notice the unloaded voltage was a touch high at 5.27v, but with my devices at idle the voltage dropped to 5.16v, and during a max stress test the voltage dropped down to 5.00v on the nose. I used mine to power a Pi 4, Pi Zero W, and USB cellular modem.

I used these to connect “battery” operated lights in a cheap tent trailer to the 12v. Works great

Works well, powers my project perfectly in a small package. Using to run a small siren (3d printed), Arduino, small led "lightbar" and a servo. No drop outs or issues, no brownouts, just steady power to run all my 5v devices from a 12v power supply (that also lowers a lightbar for a cruiser).

Good budget converter. (high end of the low cost models). This converter provides a stable 5 V output from 12–24 V sources - I use it on small electronics projects. Using an electronic load the voltage was stable at 5 A in short tests. The module is fully potted, with a compact housing, mounting ears, and color‑coded open leads. Measured outputs are generally around 5.0–5.3 V across a wide input range, with low ripple. The lack of reverse‑polarity protection means wiring errors can be destructive, so it is better suited to permanent, correctly fused installations than frequent rework. Price is somewhat higher than bare buck modules, but mechanically solid, electrically stable.

Review of ”PlusRoc Waterproof 12V/24V to 5V 5A Step Down Converter, 25W DC-DC Buck Converter...": (Please refer to my reviewing guidelines at the bottom of the page). We live on our 52' Trawler 100% of the time and anchor out and travel 99% of the time. We use these buck converters connected to 4 port USB outlets (that I built, see photo) around the boat to power 5v DC fans and USB gadgets. It seems often that we come up with a use for another one so I ordered this when it became available. This is a very nice version of the buck converter in that it not only meets the output specs (as others have shown in photos), it is very well made with high quality tinned wires. Tinned wire, commonly referred to as "Boat Cable" is very resistant to corrosion and highly important for use on a boat because of the corrosive environment a boat is normally in-- especially if in saltwater. The manufacturer should add this feature to their ad because it is a very important feature for boaters or anyone that wants to use this in an outdoor environment. I've done a bit of market research on Amazon for this specific type of product and find that the current price of $10 is just into the higher side of average for a single unit on the Amazon market. But the fact that it has high quality tinned wires makes it a good value for that price and is why I'm assigning 5 stars. My responsibility as an Amazon Vine Reviewer: Considering the Amazon rules/regulations for being a Vine Member It is obvious that it is very important to Amazon that the person doing the review has indeed inspected, tested, used the product as well as being aware of the competitive situation of the market segment. This is so it can be fairly compared and reviewed whether good, bad, average, or anywhere in all of the grey area between. One thing that I wish were better defined by Amazon is exactly what each star should represent from 1 to 5 so that every Vine member would use the same guide in that regard. So, to let you know the guide that I use, I include it as follows: I always start off considering that average is 3 stars, and an average rating to me is: The product was correctly represented in the ad. The manufacturing quality is as expected. The product performed as intended. The product operating/user guide if needed is helpful. The product is priced accordingly. Then after inspection, measuring, testing, using, wearing, or whatever is required I add or subtract from the average as follows: Subject to additional stars: Additional product features not expected that are useful. Manufacturing quality/performance above what was stated or expected. Included guides and/or useful information that is beyond the norm. Product pricing highly competitive for a superior product. Subject to fewer stars: The product was misrepresented in the ad. Manufacturing quality/performance below what was stated or expected. No useful guide or understandable user information when required. Product pricing is on the high side considering quality, features, or the market. I hope this review helps you while making your purchase decision. all the best, dr
