eHUB DC-DC Digital Step Down Converter Module LM2596 Digital with LED Voltmeter

Good product. It works as described. Note that the potentiometer requires around 20 rotations or more to set the output voltage. It will be helpful for the first time buyers if a sheet of paper with instructions on how to set the output voltage. The seller was helpful as they called me immediately when I needed help. I use the product along with a 12 volt bike battery, a Bosch C3 battery charger to provide uninterrupted 12 volt DC power supply to my broadband router. My 1100 VA UPS shutdown after 15 minutes of power failure and the current setup is a great alternative to power my broadband router for several hours after power failure

Accuracy is not perfect , price rs-395 is not suitable for this , 200-250 is enough , dont buy if u r not surego for only bunk convertor thats price lows also

Works fine, But adjustable problem

Display for input and output voltage, select with switch. Works as expected. But i think its cost is on higher side,hence lower rating.

A probable low power dc to dc step down out put voltage adjustable adapter.

God

Very heĺpful

It is good
