    very useful addition to my diy. very compact. does what it say and pleased. my problem is it looks cheaply made with flux on pcb and the input/output receptacle too small and very close! not very ideal. cables can easily short circuit and no very pleasant when dealing with voltages of 30 and of...

    Pros: Great price. Good current capability. Cons: This buck converter uses an XLSEMI XL4016E1 buck converter that is rated an 8 AMPS Maximum. Therefore the 12 AMP spec is not realistic. According to the XL4016E1 Data Sheet (google it) this device goes into shutdown if the output current exceeds a... Read more

    Pros: Stable voltage output at several amperes. Cons: Is not specially recommended to drive LEDs. There are no constant current function. As LEDs gets warmer their inner resistance are reduced, hence increased ampere draw. This module keeps the voltage stable, which means if its adjusted to maks... Read more

    Small, compact module with high power output. Tested output current to greater than 10A, voltage regulation is good. I have ordered more units, and would recommend this power supply.

    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.

    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

    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... 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... Read more
