## Questions & Answers

**Q: could this be used to power a raspberry pi? wondering if it will be able to output the 5.1v at 3 amps constantly**
A: I use them to power Pi 3b+ and Pi4.  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

### ⭐⭐⭐⭐⭐ Works with Pi 5
*by S***S on June 21, 2025*

Works great charging any smartphone and also works well with a Raspberry Pi 5. Input is LiFePO4 13.2V, output is a solid 5V 5A.

### ⭐⭐⭐⭐⭐ It Works GREAT With a Battery Made of 2, 3.65v LiFEPO4 Prismatic Cells
*by C***O on August 12, 2022*

Almost 1 & 1/2 years ago, I ordered a 10 pack of 3.2v, 50ah, Prismatic Lifepo4 cells from an online vendor. With 8 of those cells I built a 100 amp hour LiFEPO4 battery. But I had 2, 3.2v, 50ah cells remaining that I did not know what to do with.I started wondering if there was a USB module that would accept an input of a minimum of 6 volts to which I could connect the battery to charge and power USB devices. Then I discovered the DROK USB DC-DC Step Down Buck Converter capable of taking 6 volts minimum and converting it to a 5V QC 3.0 Charging Module. I read the reviews, good and bad...bad to see what people were complaining about, and decided to buy a set of 4.I figured that the converter module should work as a USB charging device when connected to the 2 remaining LiFEPO4 cells if the cells are wired in series to produce the required 6+ volts. (See the first picture of the 2 LiFEPO4 cells connected in series with one of the 2 connections coming from the converter module connected.)The second photo shows both wires connected, and the blue illuminated LED on the converter module. You can see "78% 10 m until full" on the screen of my phone. The third photo shows the charging symbol on the screen. It shows 79%. Sorry for the fuzziness of that picture.I used a few of the converter modules to charge my phone and tablet for quite a while over the last few days. I wanted to see how warm they would get. The converter module does get warm, but not too hot to handle...unlike another similar product that got far too hot to be safe. And that was only at about 1 amp of current output. I'll be submitting a brutally honest review on that one soon.I foresee finding an appropriate container in which I will cut holes for the 4 converter modules and the the 50 amp hour battery and use the power source for a portable mega-USB charging station. I'll upload pictures when I get around to making it.I am very happy that my idea panned out!

### ⭐⭐⭐⭐⭐ Buck converter.
*by M***R on May 18, 2025*

I soldered this in yesterday to a solar panel whose original one burned out. So far it is working properly in good sunlight.
