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. ## Customer Reviews ### ⭐⭐ Stopped Working *by S***L on 26 July 2025* Bought this August '24 to supply a stable voltage to a MaxxAir Deluxe fan in my motorhome which pulls a maximum of 4A. Worked great..........for about 3 weeks in the 10 months it was installed and used.

The MaxxFan is the Best and Worst RV fan in the industry. When working, it is without a doubt the best RV fan with the most air movement, quietest operation, and low amp draw of the various options out there. But it suffers from 2 manufacturing fatal flaws that have been well documented by many who have suffered the fan failure. The first flaw is the circuit board not being waterproof, and living below a vent cap that can allow outside water onto the board, or inside condensation to drip onto the board. The second flaw is the electronic components used that are extremely sensitive to voltages over 13 volts or so. This is problematic as many RVs see voltages up to 14 to 14.5 volts when receiving charge from a generator, a tow vehicle, or a solar system. So having read numerous accounts of fan failures, and methods to correct the problem, I went in search of a DC voltage regulator. This one received good reviews, was well priced, and was also used by other fixing the same issue with their own MaxxFans. I installed this voltage regulator after having to replace my failed circuit board, in the hope that this permanently solves one of the problems. I bench tested this unit before installing it, as shown in the photo, using a portable lithium battery that provided 13.3 volts output. This Autoutlet regulator held the through voltage to a constant 12.2 volts. After installation, I again tested it once connected to my RV 12 volt system, which on shore power with the battery charger active was showing over 13 volts. This regulator did a great job of holding it to 12.2 volts installed. To protect the circuit board from problem #1 (moisture) I also coated top and bottom with thin coat of GE Silicone Supreme (neutral curing silicone sealant). I'm hoping these two remedies will keep my MaxxFan operating for many more years to come, hopefully with no more flashing-green-lights-of-death. I can't speak to longevity of this voltage regulator yet as it's only been in for a few months of operation, but so far it has helped the fan work flawlessly, thru all 10 speeds, in forward and reverse, as it is meant to operate. If you're looking for a reliable Voltage regulation option, I can highly recommend this Autoutlet device and the company selling it. Check out the attached photos for visuals of how I mounted it, using hot melt glue, into the outer frame of the fan. This caused no problems with clearance even in the low profile roof of our little Coachmen Apex Nano trailer. ## Frequently Bought Together - 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 - MG Chemicals - 422B-340G 422B Silicone Conformal Coating, Clear, 340 gram Aerosol - Dicor BT-1834-1 Butyl Seal Tape - 1/8" x 3/4" x 30' Repair Tape for RV, Trailer, Motorhome, Window, and Vent Sealing --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/497649320-drok-dc-dc-stabilizer-9v-36v-to-12v-boost-buck](https://www.desertcart.be/products/497649320-drok-dc-dc-stabilizer-9v-36v-to-12v-boost-buck) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-10-11*
