Connect the wiring in strict according with the wiring instruction. 2. Use short and thick input & output wire to ensure output enough voltage and power. 3. If there are multiple output wire, do not combine the load. 4. Leave a margin for the power supply to ensure it can long-term stably working.Package Included: 1x DC-DC Stabilizer

Review: Works great with MaxxFan for voltage regulation. - Easy install and quick-fix for MaxxFan voltage errors. Fits inside MaxxFan housing.
Review: Spectacular failure - 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.

## Questions & Answers

**Q: If  it fails, does it pass the input voltage straight through or does it block it?**
A: Blocks it and doesn't work

**Q: Vent fan connect to led interior light. led burns out. can this stabilize interior led power save from burn out??**
A: Only one word, excellent !!!!

**Q: Several people have asked if the grounds on this module can be tied together. i asked drok, an they said yes, because the module is non-isolated. ok?**
A: Black wires are already tied together inside module.  One black wire (ground/ return) goes to input, second black wire goes to output/ load.  Have a blessed day!

**Q: Can the 2 negatives share a common ground?**
A: This goes in the line.  You will have a positive and negative going to your load.  You  cut the wires and hook the positive and negative from your power sorce to ine in-side and the positive and negative coming out go to the load.  Simple.
