We found 3 Reddit mentions of DROK 180051US Numerical Control Voltage Regulator DC 5-32V to 0-30V 5A Buck Converter, 24V 12V to 5V Step Down Power Converter Adjustable Digital Control Voltage Reducer. Here are the top ones.
or
- 5-32V to 0-30.0V adjustable buck CC CV converter with volt amp display. 0-5A constant current / voltage output, over 2A please add a heatsink.
- Numerical Control: there are "-" button for decreasing output voltage/current and output adjustment "+" for increasing output voltage/current in setting mode.
- Dual LEDs accurately displays volts & amps simultaneously. Press the "OFF / ON" button to switch to turn on/off the output. In working mode, you can switch the input and output voltage display.
- Setting current and voltage limits: press the "SET" button to select the digit you want to change, then use the "+" "-" buttons to increase or decrease the value. Press "SET" again to move to high-digit. Press "OFF / ON" button to determine the data.
- Neatly laid out and soldered, with the mounting holes, which is easy to hook up the wires. You can use it to DIY a high-power LED constant current driver, rechargeable lithium batteries charging, solar panels, etc.

This can be accomplished with a voltage converter and a voltage regulator design for solar power for less than fifteen bucks
EDIT: People wanted details.
Batteries, panel, wiring, tools, housings, not included.
There's a bunch of better guides online, but the main components are a voltage converter, and a charge controller to get your pi powered by battery while charging the battery with what solar is available.
I think their product requires more investment than that little hat, personally. Do you think that little thing is going to step down 12v-5v with good heat management? I don't think it handles power conversion, and there might be something else in the line before it, like a regulator. Maybe you need their 12v battery.
But like any kickstarter, no guarantee on delivery of product, or features so be skeptical.
(looking for guide that I used...)
No need to paypal, please just post your results! Success or failure, we want to see, learn and maybe help! Going straight from one battery to another poses the same problem as going from solar to battery directly. Little or no control. You can get basic buck down constant current constant voltage power supplies that would work with these. Again, they won't be smart and may have some ripple in their voltage, but they should work as long as you input the right stuff. https://www.amazon.com/dp/B01CE5P33M/ref=cm_sw_r_sms_apa_G9NHzbZ3YAENK. Be super careful, watch and measure voltage regularly, and set the voltage conservatively low to start. I'd start at 3.7 volts per cell. Best of luck!
Just test it with the power supply before hooking it up to batteries? Still a good idea to have a fuse and some kind of current limiter, either resistive or one of those Drok board you can get on Amazon for $10.
If you want something a bit more straight forward Hobbyking has a packaged device that does the same and more... can’t find a link, I’ll post one when I find it.
