Review on π USB Buck Converter DROK 4pcs DC-DC Step Down Module 6-32V 12V 24V to 5V QC 3.0 Charging Module Power Supply Voltage Regulator Board by Ray Reeltalk
Super high quality boards
They look a lot better than the ones I've used before. They're also small and still capable of delivering 3A. I designed a simple 3D printed case for this and made a small module out of some battery contacts that connects to my Ryobi batteries. Total only costs $3 in parts to make one. Much better than the $80 Ryobi power module. Of course, it comes with an AC inverter, but pretty much everything I need is powered via a USB cable anyway.
- Sturdy construction
- Doesn't fit all
