They feature wide input voltage, low power consumption, high efficiency, high reliability. We provide different power voltage converters for all kinds of application devices. Compact Size Compact aluminium shell with epoxy potting is anti-shock, damp-proof ,anti-dust protections and better heat dissipation Intelligent Protection Assembled with smart chip--has features of Over-current /Over-load /Low-load /Short-circuit /Over-heat intelligent protection Synchronous Rectification Technology The synchronous rectifier circuit use MOSFET instead of rectifier diode to greatly reduce the loss of the rectifier and improve the converter efficiency Features Non-Isolated Module Input Voltage: 12V/24V/36V nominal, Input range: 8V-40V Input Current: 10A (max) ; No-load input current: ≤10mA Output Voltage: DC 12V ±2% ; Output Current: 3A Ripple Wave: 50Mv Starting Delay time: ≤ 2S Efficiency: ≥95% Operating Temperature:-40 ~ 80℃ Net Weight: 110g / 3.8oz Package Include 1x Buck Boost Converter 8V-40V to 12V 3A 36W IP68 Waterproof Module Better Heat Dissipation Strict glue pouring process is waterproof, moisture-proof, seismic and adapt to a variety of harsh environment. Aluminium shell improve better heat dissipation effect and sturdiness to extend service life. SMT Process FR-4 multilayer lines, resistors, capacitors and switch MOS tube are SMD components with high integration, high reliability, high stability. Notes: It's normal that the case is hot when converter inside temp is over 113℉, converter will protect itself when inside temp is over 185℉. Wide Applications T hese compact size dc voltage reducer converters are high reliability power transformers. They can work safely and reliability within temperature range -40°C~80°C. Widely used to golf cart, motor, speaker, GPS, LED car display screen, air-conditioner, electric fan, solar energy, photo-voltaic power, DVD, industrial equipment ect. Review: Worked perfectly - I bought this to step down a battery that was rated at 12v but was actually delivering 18v. I wanted to power a telescope mount but not fry its electronics. Fortunately, I'm cautious enough to test the battery before just blindly hooking it up. With this in the circuit, the battery delivers a nice even 12v. Review: Excellent performance. - I'm using this to power a Tech2 to avoid the typical Tech2 reboot while starting the vehicle. For that it works beautifully. I bench tested all the way down to 5.5 volts and it still maintained the full 12v output. Very happy with my purchase, we'll see how long it lasts. ## Features - voltage converter ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07V8K6YZ6 | | Best Sellers Rank | #30,099 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #8 in Power Transformers | | Brand | HOMELYLIFE | | Brand Name | HOMELYLIFE | | Current Rating | 3 Amps | | Customer Reviews | 4.6 out of 5 stars 197 Reviews | | Item Weight | 110 Grams | | Manufacturer | EPBOWPT | | Model | 8-40V/12V | | Mounting Type | Surface Mount | | Part Number | 8-40V/12V | | Power Source | Dc Powered | | Specification Met | CE, RoHS | | UPC | 192834003323 | | Unit Count | 1.0 Count | | Warranty Description | 6 months | ## Product Details - **Brand:** HOMELYLIFE - **Current Rating:** 3 Amps - **Mounting Type:** Surface Mount - **Power Source:** Dc Powered - **Specification Met:** CE, RoHS ## Images ![Voltage Reducer DC 8V-40V to 12V 3A 36W Automatic Buck Boost Converter Step Down Up Regulator Waterproof Module Transformer for Golf Cart Club Car - Image 1](https://m.media-amazon.com/images/I/71GeP5ChGgL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked perfectly *by C***M on May 27, 2025* I bought this to step down a battery that was rated at 12v but was actually delivering 18v.

Very happy with my purchase, we'll see how long it lasts. ### ⭐⭐⭐⭐⭐ This is just great *by D***Y on November 30, 2023* Great product, works exactly as expected. However, at one point I made a careless error and accidentally reversed polarity on the input and burned out something in the circuit. The internals aren't easily accessible, they're filled with some kind of rubber material so I can't easily replace whatever burned out. If y'all could add an easily accessible diode that could be swapped out to protect against accident prone people like me that would make a great product even better. ## Frequently Bought Together - Voltage Reducer DC 8V-40V to 12V 3A 36W Automatic Buck Boost Converter Step Down Up Regulator Waterproof Module Transformer for Golf Cart Club Car - Digital Low Voltage Protector Disconnect Switch Cut Off 12V Over-Discharge Protection Module for 12-36V Lead Acid Lithium Battery Low Voltage Cutoff for Solar Panel Lighting System Camper --- ## 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.be/products/148982939-voltage-reducer-dc-8v-40v-to-12v-3a-36w-automatic](https://www.desertcart.be/products/148982939-voltage-reducer-dc-8v-40v-to-12v-3a-36w-automatic) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-06-23*
