I think these modules need a heat sink to function at their full specification. Might work better at half spec. Review: Works great for converting small AC electronics into battery power. - Have been using these for awhile to convert small solid state guitar amps to portable battery operation. No issues dialing in the proper +\- DC voltages. Make sure you don’t accidentally hook the input voltage incorrectly as smoke will come out (my fault one piece, whoops😬). ## Features - It is a Adjustable Dual Output Step UP/Down Power Supply Module with input DC 3.6V~30V and output DC +/-3V~30V. - It has fixed output voltage and dual voltage output. - Low power consumption, adjust the potentiometer on the module to change the output voltage. - Input voltage:DC 3.6V~30V Output voltage:DC +/-3V~30V - After-Sale Service: Thanks for your purchase. If you have any problem , please feel free to contact us any time. We promise you the satisfying solutions within 24 hours. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08YYX14PS | | Best Sellers Rank | #240,891 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #1,010 in Power Converters | | Brand Name | MiOYOOW | | Customer Reviews | 3.8 3.8 out of 5 stars (27) | | Item Weight | 0.03 Kilograms | | Manufacturer | MiOYOOW | | Maximum Frequency | 400 KHz | | Minimum Frequency | 50 Hz | | Model | 1 | | Mounting Type | PCB Mount | | Part Number | 1 | | Power Source | Dc Powered | | UPC | 770429487033 | ## Product Details - **Brand:** MiOYOOW - **Item Weight:** 0.03 Kilograms - **Mounting Type:** PCB Mount - **Power Source:** Dc Powered - **UPC:** 770429487033 ## Images ![Boost Buck Voltage Converter, DC-DC 5V-24V to +/-3V-30V Step UP Down Power Supply Module Adjustable 20W Positive Negative Dual Output Voltage Charging Converter for Amplifier - Image 1](https://m.media-amazon.com/images/I/612rek1q6jL.jpg) ![Boost Buck Voltage Converter, DC-DC 5V-24V to +/-3V-30V Step UP Down Power Supply Module Adjustable 20W Positive Negative Dual Output Voltage Charging Converter for Amplifier - Image 2](https://m.media-amazon.com/images/I/61N3Fqo1puL.jpg) ![Boost Buck Voltage Converter, DC-DC 5V-24V to +/-3V-30V Step UP Down Power Supply Module Adjustable 20W Positive Negative Dual Output Voltage Charging Converter for Amplifier - Image 3](https://m.media-amazon.com/images/I/61schQkivqL.jpg) ![Boost Buck Voltage Converter, DC-DC 5V-24V to +/-3V-30V Step UP Down Power Supply Module Adjustable 20W Positive Negative Dual Output Voltage Charging Converter for Amplifier - Image 4](https://m.media-amazon.com/images/I/61H+6rGUc3L.jpg) ![Boost Buck Voltage Converter, DC-DC 5V-24V to +/-3V-30V Step UP Down Power Supply Module Adjustable 20W Positive Negative Dual Output Voltage Charging Converter for Amplifier - Image 5](https://m.media-amazon.com/images/I/61kkl58J85L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Seems to work *by W***) on June 2, 2023* I was unable to get the correct voltage. I think these modules need a heat sink to function at their full specification. Might work better at half spec. ### ⭐⭐⭐⭐⭐ Works great for converting small AC electronics into battery power. *by M***E on December 24, 2023* Have been using these for awhile to convert small solid state guitar amps to portable battery operation. No issues dialing in the proper +\- DC voltages. Make sure you don’t accidentally hook the input voltage incorrectly as smoke will come out (my fault one piece, whoops😬). ### ⭐⭐⭐⭐ Only adjustable on one side. *by W***I on June 2, 2025* Works ok. No separate adjustment for + and - outputs. +5.15v gets you almost -6 on the other side. No holes for mounting so you will have to glue/silicone it in place. Other than that I’m happy with it, it’s working for my project. ## Frequently Bought Together - Boost Buck Voltage Converter, DC-DC 5V-24V to +/-3V-30V Step UP Down Power Supply Module Adjustable 20W Positive Negative Dual Output Voltage Charging Converter for Amplifier - DROK Micro Dual Power Supply - DC to DC Buck Boost Converter 4.8-35V to ±15V Positive Negative Dual Output, Step Up Voltage Regulator for OP-Amps - DONGKER TPS5430 Voltage Regulator Module,DC-DC -12V 12V Positive Negative Dual Output Module Power Supply Module with Switching --- ## 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.tn/products/363357083-boost-buck-voltage-converter-dc-dc-5v-24v-to-3v](https://www.desertcart.tn/products/363357083-boost-buck-voltage-converter-dc-dc-5v-24v-to-3v) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-06*
