Works as expected, very useful thing.
Many electronic devices, such as TV in mobile homes are very sensitive to over voltage (<12V) during charging, and many people in forums write about that problem. This circuit will save all these situations. My tests are 100% positive. Read more
Pros: this device I use to connect my 12v led lights to my 24v battery and works exactly as described. I am very happy with this products you can use it to connect almost an dc device to a battery aslong as you adjust the voltage correctly. Cons: can be very inefficient Read more
the converter can easily be mounted in an apprpriate plastic housing, I made this possible with cutting away the sides of the housing so the cooling of the item are open.
The product works as advertised as a step down converter with about 1V input over output needed to regulate the voltage. Under this value the output voltage equals input. Read more
Easy to use and connect, compact and powerfull!!! With this small circuit, you will can drive up to 12Amps, and 4,5 to 30Volts!!! You will need an extra potentiometer to choose volts, because the variable resistor is too smal, and complicates the volt regulation, and when you increase power, you will need a fan to cool the transistors!!! I have no more ... Read more
