Adjustable range: 1-16V; Fixed voltage: 1.8V, 2.5V, 3.3V, 5V, 9V, 12V; Output current: Max 3A (peak: 3A, long-term: within 2A); Power: 10W. - Output Voltage Adjustable or Fixable --- The tiny buck converter board can be changed to adjustable output voltage or a fixed one. The reducer is default to be used for adjustable voltage output. If you want to get fixed voltage output, you need to cut off the Pad A by using a sharp thing such as a knife, then weld together the port of the fixed voltage you want. - High Efficiency --- Big energy in small size. The conversion efficiency of this volt transformer can be up to 97% (typical value: >90% when step down 12V to 5V 2A). - Protection and Enable Control --- The 12V buck converter is designed with output short circuit protection, but please do not keep short circuit for a long time. Also, the reducer is equipped with an integrated enable port which defaults the working mode that it will be off when it is at low electric level off, which bring a great convenience for users. - NOTE --- This mini buck converter is really very tiny, much smaller than a 1-dollar coin, nearly a half of the coin. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08Q3TKJH5 | | Best Sellers Rank | #42,153 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #171 in Power Converters | | Brand | DROK | | Color | Black | | Customer Reviews | 4.3 4.3 out of 5 stars (36) | | Input Voltage | 20 Volts | | Item Weight | 0.63 Ounces | | Manufacturer | DROK | | Number of Outlets | 10 | | Output Voltage | 5 Volts | | Power Source | Corded Electric | | Unit Count | 10.0 Count | ## Product Details - **Brand:** DROK - **Color:** Black - **Input Voltage:** 20 Volts - **Item Weight:** 0.63 Ounces - **Output Voltage:** 5 Volts ## Images ![DC 12V to 5V Buck Converter, 10pcs Mini Voltage Regulator Board DC 4.5-20V 12V 9V Step Down to 1-16V 5V Reducer 3A Fixed Adjustable Volt Output Transformer Power Supply Stabilizer Module - Image 1](https://m.media-amazon.com/images/I/71AZ2j+nf2L.jpg) ![DC 12V to 5V Buck Converter, 10pcs Mini Voltage Regulator Board DC 4.5-20V 12V 9V Step Down to 1-16V 5V Reducer 3A Fixed Adjustable Volt Output Transformer Power Supply Stabilizer Module - Image 2](https://m.media-amazon.com/images/I/71n0xRrs5ZL.jpg) ![DC 12V to 5V Buck Converter, 10pcs Mini Voltage Regulator Board DC 4.5-20V 12V 9V Step Down to 1-16V 5V Reducer 3A Fixed Adjustable Volt Output Transformer Power Supply Stabilizer Module - Image 3](https://m.media-amazon.com/images/I/71G2+HN7+0L.jpg) ![DC 12V to 5V Buck Converter, 10pcs Mini Voltage Regulator Board DC 4.5-20V 12V 9V Step Down to 1-16V 5V Reducer 3A Fixed Adjustable Volt Output Transformer Power Supply Stabilizer Module - Image 4](https://m.media-amazon.com/images/I/81PgV0EWZJL.jpg) ![DC 12V to 5V Buck Converter, 10pcs Mini Voltage Regulator Board DC 4.5-20V 12V 9V Step Down to 1-16V 5V Reducer 3A Fixed Adjustable Volt Output Transformer Power Supply Stabilizer Module - Image 5](https://m.media-amazon.com/images/I/71X50Ntz1+L.jpg) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - DROK DC 12V to 5V Buck Converter, 10pcs Mini Voltage Regulator Board DC 4.5-20V 12V 9V Step Down to 1-16V 5V Reducer 3A Fixed Adjustable Volt Output Transformer Power Supply Stabilizer Module - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - 22 AWG Solid Core Wire Kit – 22 Gauge PVC Coated Copper Wires Pre-Tinned 33ft or 10m Each, 6 Colors (Black, Red, Yellow, Green, Blue, White), Hook Up Wire Kit from Plusivo --- ## 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.us/products/280575558-dc-12v-to-5v-buck-converter-10pcs-mini-voltage-regulator](https://www.desertcart.us/products/280575558-dc-12v-to-5v-buck-converter-10pcs-mini-voltage-regulator) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-17*
