When you encounter this problem, please firstcounterclockwise rotation potentiometer 10 laps above, and then use the modulecan be normal adjustment of the voltage.Note:The input and output interface can not be reversed. Keep it under 2.5 A and use the heat sink when working for long hours.(Factory default stays a high voltage, you need to contrarotate about 7-15 circles before the voltage starts changing, 1 circle means +/- 1V). Review: Product has been working great - So far so good, bought these for my DJI 03 air system. Has been operating 03 air and a fan at the correct current/adjustable also. Thankx! Review: Very useful - This buck converter is fantastic! Holds the set voltage well. Easy to install and use. ## Features - ★Input： DC 3-40 V (input voltage must be 1.5 V higher than the output voltage, no boost). - ★Output: DC 1.5-35 V voltage is continuously adjustable, maximum output current is 3 A. - ★Easy work: convenient to accurately adjust the output voltage with a mini screwdriver. - ★Features: use SANYO solid-state capacitors,36u thickening circuit boards, high-Q inductance with LED indicator output. - ★Application: widely used for DIY mobile power, monitor power supply, communications equipment supply,etc. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08CGL6FQD | | Brand | DaFuRui | | Brand Name | DaFuRui | | Current Rating | 3 Amps | | Customer Reviews | 4.6 out of 5 stars 46 Reviews | | Item Highlight | Input 3-40V, output 1.5-35V, adjustable voltage, stable power supply, for DIY electronics projects. | | Manufacturer | DaFuRui | | Minimum Frequency | 50 Hz | | Model Number | LM2596 | | Mounting Type | PCB Mount | | Number of Items | 10 | | Number of Packs | 10 | | Part Number | LM2596 | | Power Source | Dc | | Power Source Type | Dc | | UPC | 747966641198 | | Unit Count | 10.0 Count | ## Product Details - **Brand:** DaFuRui - **Current Rating:** 3 A - **Mounting Type:** PCB Mount - **Number of Items:** 10 - **Power Source:** DC ## Images ![LM2596 Buck Converter 10Pack Adjustable Step Down Module - Image 1](https://m.media-amazon.com/images/I/81s6vpOJ8aL.jpg) ![LM2596 Buck Converter 10Pack Adjustable Step Down Module - Image 2](https://m.media-amazon.com/images/I/71lJENT83ZL.jpg) ![LM2596 Buck Converter 10Pack Adjustable Step Down Module - Image 3](https://m.media-amazon.com/images/I/71aqIayNBlL.jpg) ![LM2596 Buck Converter 10Pack Adjustable Step Down Module - Image 4](https://m.media-amazon.com/images/I/71OMmgWCgUL.jpg) ![LM2596 Buck Converter 10Pack Adjustable Step Down Module - Image 5](https://m.media-amazon.com/images/I/81yD-LoYd4L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Product has been working great *by M***N on 5 April 2025* So far so good, bought these for my DJI 03 air system. Has been operating 03 air and a fan at the correct current/adjustable also. Thankx! ### ⭐⭐⭐⭐⭐ Very useful *by L***X on 23 June 2026* This buck converter is fantastic! Holds the set voltage well. Easy to install and use. ### ⭐⭐⭐⭐⭐ Great for DIY projects converting higher DCV to lower DCV. *by M***E on 14 February 2024* Have been converting small AC powered electronics (guitar amps) to DC battery operation for a while now. These work great and maintain a consistent output voltage even when the battery (Li-ion) drops slightly during operation. --- ## 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.ec/products/543134176-lm2596-buck-converter-10pack-adjustable-step-down-module](https://www.desertcart.ec/products/543134176-lm2596-buck-converter-10pack-adjustable-step-down-module) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-09-25*
