No issues came perfectly sealed, shiney and awaiting your project! Review: Not 24v input. - NOT 24V tolerant! Blew up two of these trying to buck 24V to 5V for a project. These definitely don't accept 24v input. ## Features - Voltage regulator input voltage range is DC 4.5-24V, adjustable range is 0.8-17V, fixed output are 1.8V, 2.5V, 3.3V, 5V, 9V, 12V that can be chosen on the back side. Max output current: 3A (please enhance cooling work when it is full load); If the actual test input is 12V and output is 1.5A, no other system is required. - Adjustable and fixed voltage output, you can get fixed output voltage by soldering the pot on the board of regulator module; You can also adjust the fixed output voltage by potentiometer as you needed. Default output is adjustable. Note: if you need to fix the output voltage, use a knife to cut the wires in the red circle in the picture, and then connect the pads with solder at the voltage you need. - High efficiency and super compact size, high frequency and low ripple, stable working performance, wide range of applications, this 12v to 5v converter will be a good component for fixing work. - Integrated enable port defaults the working mode and it will be off when it is at low electric level off, which bring a great convenience for users. NOTE: This 5v step down converter is really tiny, each unit is smaller than half a one-dollar coin. - Convenient to use, integrated enable port of the regulator board defaults to working mode and will be closed when it is at low electric level off, and with ultra-low quiescent current, quiescent current is 0.85 mA; It can be connected to the car battery without a switch, cigarette lighter cord or the ACC power cord. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08Y674Z6F | | Best Sellers Rank | #170,891 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #701 in Power Converters | | Brand Name | DORHEA | | Current Rating | 1.5 Amps, 3 Amps | | Customer Reviews | 3.3 3.3 out of 5 stars (52) | | Item Weight | 0.04 Kilograms | | Manufacturer | DORHEA | | Maximum Frequency | 500 KHz | | Minimum Frequency | 50 Hz | | Model | B08Y674Z6F | | Mounting Type | PCB Mount | | Part Number | 13680-1 | | Power Source | Battery Powered, Corded Electric | | Specification Met | FCC, UL | | UPC | 701715461765 | ## Product Details - **Brand:** DORHEA - **Current Rating:** 1.5 Amps, 3 Amps - **Mounting Type:** PCB Mount - **Power Source:** Battery Powered, Corded Electric - **Specification Met:** FCC, UL ## Images ![Dorhea 10PCS 5V Regulator Module Mini Voltage Reducer Adjustable DC 4.5-24V 12V 24V Step Down to 5V 3A Buck Converter Board Reduced Voltage Regulator Power Supply Transformer Module - Image 1](https://m.media-amazon.com/images/I/81PUyiyX2aL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Regulators mount up! 😆 *by M***N on February 24, 2026* Still working with them but they seem great to me. No issues came perfectly sealed, shiney and awaiting your project! ### ⭐ Not 24v input. *by B***T on January 15, 2026* NOT 24V tolerant! Blew up two of these trying to buck 24V to 5V for a project. These definitely don't accept 24v input. ### ⭐⭐⭐⭐⭐ Works great! Must cut trace above adjustable pads for fixed voltages to work *by H***Y on April 22, 2024* These work great for a esp32 project I am working on. Keep in mind, these are designed to used the adjustable pot by default. If you want to use the fixed voltages then you need to break the trace right above the adj pads. There are two dots, break the trace between them. ## Frequently Bought Together - Dorhea 10PCS 5V Regulator Module Mini Voltage Reducer Adjustable DC 4.5 - 24V 12V 24V Step Down to 5V 3A Buck Converter Board Reduced Voltage Regulator Power Supply Transformer Module - KOOBOOK 5Pcs DRV8833 Motor Drive Module 1.5A Dual H Bridge DC Gear Motor Driver Controller Board - ESP-WROOM-32 ESP32 ESP-32S Development Board 2.4GHz Dual-Mode WiFi + Bluetooth Dual Cores Microcontroller Processor Integrated with Antenna RF AMP Filter AP STA Compatible with Arduino IDE (3PCS) --- ## 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.nz/products/380170134-dorhea-10pcs-5v-regulator-module-mini-voltage-reducer-adjustable-dc](https://www.desertcart.nz/products/380170134-dorhea-10pcs-5v-regulator-module-mini-voltage-reducer-adjustable-dc) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-05-17*
