It works
The product works but if you want to embed it into something its worth removing the USB since it adds to much size to the board, would be nice if the potentiometer wasn't so massive but I assume it has been made for a specific use case

Don't Bother, poor quality
These were purchased to use on an electronics project to control the voltage on some simple breadboards, so far on one the adjustable resistor has blown and will not go any higher than 5.1 volts and one other has had a part of the circuit board smoke out ( a diode I think ) and now appears to be dead It was not connected to the board at the time just a 12volt supply.... I dread to think how long the last o the 3 will last.These are the same as the ones sold on TEMU but cost about £1 each more.

Flexible
All items fully functional. Useful to have varied input range and especially output voltage range above and below input. Onboard output voltage display saves having to add separate one to monitor.

DIY 6v charger
The media could not be loaded. Great converter a must for electronics work
