DROK DC-DC Stabilizer, 9V-36V to 12V Boost Buck Converter 5A 60W Waterproof Auto Step Up Down Voltage Regulator 12V Volt Transformer for Car Audio Solar Power System LCD Television LED Display Screen

Works awesome! My application requires close to 12 volts with the input voltage varying from 11.5 - 14 volts. This does the trick holding the output voltage at exactly 12.5 volts across an even larger input voltage range than I require. Admittedly, I would have been fine with the 3 amp version but chose the 5 amp to provide additional current capacity. I am drawing 1.7 amps continuous and it does not even get warm to the touch.

Our Maxfan wasn't working when we bought the fan, and just by attaching the voltage controller, now it is working great.

I used this for a step-down voltage 5v output on a portable ham radio setup for POTA since November. Everything else required 12v, the tuner required 5v so I added this in line for its power. Seemed to work well. Yesterday the device failed spectacularly. Sudden "pop" noise, smoke, and even flame for a couple of seconds where the case had split. I had to evacuate the car until the smoke had dissipated. Glad I was there when it happened. Definitely done with these things, I will replace those I'm running at home as well. I can't trust them.

Works great by stabilizing output voltage

Great product. Working perfectly.

Works are described. The one I received put out 12.37v from 8 to 15 v input. Solid unit.

I wanted to connect my 10 amp (20 volt) solar panel to a small 12 volt water pump. The voltage of the solar panel varies between 20 volts down to zero depending on the sunlight and I wasn't sure the that the small pump would take more than 12 volts so I connected this in between the solar panel and the pump. Worked perfectly. In bright sunlight the panel puts out 20 volts and the unit drops the voltage down to 12 volts for the pump. Problem solved! Specs say it will take in up to 36 volts and output 12 volts at a maximum of 5.6 amps. The solar panel puts out about 20 volts at a maximum of 2 amps, this unit drops the voltage down to 12 volts. Works fine. In addition, the unit is well sealed and seems weatherproof, which is important since I have it mounted outside of the water fountain in the weather and exposed to the elements.

This DC to DC converter supplies 12v to my Eversecu Mod:ES-AHD-BGZ5 "HD Analog IR PTZ Dome Camera", mounted 80 feet up on a tower, So it's a big deal to replace when it fails. This is the second 5A, 60 watt unit to fail in 12 months. The first one destroyed the camera it supplied by passing 34vdc to the cameras 12v input. This time I was lucky, the camera survived, but there is still the issue of accessing it to replace it, 80 feet up the tower. I thought I'd give Drok one more try since I am happy with a different one of their products. So I bought a "F36W12V10A5L", 9V-36V in 12V 10A out model and it failed in 20 minutes, before I could even raise it up on the tower. @ $27 I expected longer service life especially with such a minimal 600ma load. Meanwhile my security system is down until a replacement arrives(next week, I'm told)
