No problems at all. The Pi's are used in radio applications which use 18.8V power. More convenient to power off the 13.8v power rails. I also use it to power a Pi3B+ used in Octoprint for my Ender 3 printer. 24v power taken from the Ender 3 power supply through the buck to power the Pi. **Q: Do you have a suggested way to mount these usb boards? Is there an adapter housing?** A: I used Hammond 1551USB2BK housing and mounted using epoxy. **Q: Does this have low voltage protection that automatically shuts off when voltage drops below 12 volts? If so, can you turn it off?** A: The input range is 6-32V. I operate mine at 6-8V typically. You don’t have to do anything special for this. **Q: do they auto cut off when battery is charged?** A: No. As long as there is power to the converter it will supply power at the USB port. The device being charged should have its own battery management system to cut off power when appropriate. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***M on 14 December 2023* I removed the USB connector as I wanted to direct-wire a USB cable to the board. I would be nice to have a solder-pad output option rather than only the USB port. ### ⭐⭐⭐⭐⭐ Review *by W***. on 5 November 2021* Product looks as sold. Each unit has performed well. Recommend! ### ⭐⭐⭐⭐⭐ Review *by R***C on 25 August 2025* Great little modules we use within our line of products to run a microcontroller off of 12v. Very low RF noise compared to other buck converters we have tested and stable voltage. We can't really speak as to how they work under high load, as we only draw about 20mA from them, but we load test each one at 2 amps for 30 seconds and I don't believe we've ever had a dud out of 100+. At the power levels we draw heat is not an issue at all but it would be important to test this for high draw applications. We typically see a power conversion efficiency of about 85% from 12v to 5v@2A when load testing. Module size is always extremely consistent, which is important as we insert them into an enclosure with extremely tight tolerances. We chose this module for our product because of the consistent specifications, low cost, and low noise which is important as our microcontroller generates audio for a radio. ## Frequently Bought Together - DROK USB Buck Converter, 4pcs DC-DC Step Down Module 6-32V 12V 24V to 5V QC 3.0 Charging Module Power Supply Voltage Regulator Volt Transformer Board - MP1584EN 5pcs Mini 5V Buck Converter Board - 5-30V to 5V, 1.8A Output, Small Size, Black - ALLECIN IRLZ44N IRLZ44 MOSFET Transistors 47A 55V IRLZ44NPBF Logic Level Mosfets 47 Amp 55 Volt TO-220 (Pack of 10Pcs) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.dk/products/280334712-usb-buck-converter-4pcs-dc-dc-step-down-module-6](https://www.desertcart.dk/products/280334712-usb-buck-converter-4pcs-dc-dc-step-down-module-6) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-04-28*
