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: Stopped Working - 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. Now there is no output. Review: Works to regulate output voltage - Cannot attest to it boosting 9v to 12v. It does buck (regulate) 14.5v down to 13.2v. Solved a problem with security cameras occasionally shutting down do to high a input voltage. ## Features - PARAMETER --- DROK DC-DC converter input voltage range is DC 9~36V (12V); output voltage is DC 12V; output current is 5A; output power is 60W. - APPLICATION --- the 12v buck boost converter module can be used in integrated wiring for monitoring fire alarming system; car radio, audio; bus, minibus, truck display screen, taxi advertising screen; LCD television, LED; solar power generation system; interphone, etc. - PROTECTION --- this voltage stabilizer comes with over-current protection, over-temperature protection; adopts potting technology, characterized by waterproof, dust-proof, moisture-proof and shock-proof, can be used in various situations such as car, outdoor, underground, etc. - FEATURE --- the step down power module adopts high-integrated chip, stable and reliable; synchronous rectification technology, with conversion efficiency of over 90% and low heat generated. - NOTE --- Leave a margin for the power supply to ensure it can long-term stably working. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B081RG8XP5 | | Best Sellers Rank | 517,527 in DIY & Tools ( See Top 100 in DIY & Tools ) 550 in Transformers (DIY & Tools) | | Brand | DROK | | Brand Name | DROK | | Colour | Plastic Shell | | Customer Reviews | 3.9 out of 5 stars 446 Reviews | | Input Voltage | 9 Volts | | Input voltage | 9 Volts | | Item Dimensions | 39 x 57 x 22 millimetres | | Item Weight | 2.39 Ounces | | Item dimensions L x W x H | 39 x 57 x 22 millimetres | | Item weight | 2.39 Ounces | | Manufacturer | DROK | | Manufacturer Part Number | 200494 | | Model Number | 200494 | | Number of Outlets | 1 | | Output Voltage | 12 Volts (DC) | | Output voltage | 12 Volts (DC) | | Plug Type | Type C | | Power Source | Solar | ## Product Details - **Brand:** DROK - **Colour:** Plastic Shell - **Item weight:** 2.39 Ounces - **Input voltage:** 9 Volts - **Item dimensions L x W x H:** 39 x 57 x 22 millimetres ## Images ![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 - Image 1](https://m.media-amazon.com/images/I/61Kjl410K8L.jpg) ![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 - Image 2](https://m.media-amazon.com/images/I/61xy0ZE38gL.jpg) ![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 - Image 3](https://m.media-amazon.com/images/I/61X9i3M7lVL.jpg) ![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 - Image 4](https://m.media-amazon.com/images/I/61uqUHD1CJL.jpg) ![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 - Image 5](https://m.media-amazon.com/images/I/61JvMO7hfIL.jpg) ## 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. ## 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.
