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: It worked to convert an alternators 14v to a steady 12v to feed a microcontroller. High quality feeling and thick gauge wire. Review: 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. ## Features - PARAMETER --- DROK DC-DC converter input voltage range is DC 9-36V (9V 12V 24V 36V); output voltage is DC 12V; maximum output current is 10A; output power is 120W. - 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.

High quality feeling and thick gauge wire. ### ⭐⭐ Review *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. Now there is no output. ### ⭐⭐⭐⭐⭐ Review *by J***. on 19 August 2024* I wanted a steady 12 volts for my CPAP machine when running off a battery when can vary from just over 13 volts to under 12 volts. So far this converter seems to put out a steady 12.3 volts and the CPAP machine is happy. BTW, I paired it with a ERYY "12V LiFePO4 Lithium Battery, 4000+ Deep Cycles Battery with BMS, Perfect for Off-Grid Solar, Trolling Motors, Boat, Marine, RV, Solar, etc (12V 25Ah Plus (30Ah))" and after 4 nights it still shows over 70% charge. I don't use water or a heater with the CPAP machine. ## Frequently Bought Together - DROK Boost Buck Converter 9V-36V to 12V 10A 120W Aluminium Shell Waterproof Auto Step Up Down Voltage Regulator 12V Volt Transformer for Car Audio Solar Power System LCD Television LED Display Screen - Victron Energy SmartSolar MPPT Solar Charge Controller (Bluetooth) - MPPT Charge Controller for Solar Panels - 100V 20 amp 12/24/48-Volt - Victron Energy SmartShunt Battery Monitor (Bluetooth) - Victron Smart Shunt - 6.5V-70V - 500 amp --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/471088855-boost-buck-converter-9v-36v-to-12v-10a-120w-aluminium](https://www.desertcart.hr/products/471088855-boost-buck-converter-9v-36v-to-12v-10a-120w-aluminium) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-23*
