It converts a wide input voltage range (10-24V DC) down to a stable 9V output at up to 1.7A (15W max), housed in a durable epoxy-sealed waterproof case. Featuring comprehensive overload and voltage protections, this lightweight converter ensures reliable, safe power delivery in demanding environments. ## Description This miniature DC-DC step-down converter module converts a 10V to 24V (perfect for 12V automotive) DC input to 9V DC output at up to 1.7A current (15W maximum).Specifications:Epoxy sealed waterproof housingLightweight, compact, convenient to use and transportNon-isolatedWith overload / over-current / over / low voltage protection, stable performanceAuto recoveryInput voltage: DC 12V nominal, will operate on any input voltage from 10V to 24V DCQuiescent input current (no load attached): 96%Size (L x W x H): 38 * 27 * 23 mm (Length including mounting tabs is 52mm)Weight: 30gCase color: White Cable length: 12cm (approx)Operating Notes:As with any DC-DC converter, the input DC power supply powering this converter must be capable of providing the maximum power drawn by your load. If the input supply is not capable of providing the power, the converter will fold back the output voltage as necessary. Example: If your load draws 1.7A at 9V (15W), and the input supply is only capable of providing 12V at 1/2A (6W), the maximum output voltage the converter will deliver is 3.5V (6W/1.7A).Package includes:1X 12V to 9V 1.7A Mini DC-DC Step Down Converter ## Features - Highly Efficient Buck Converter: This miniature DC-DC step-down converter module converts a 10V to 24V (nominally 12V) DC input to 9V DC output, with an output current of up to 1.7A (15W maximum). - Versatile Voltage Input: This step-down converter will operate on any input voltage from 10V to 24V DC, making it highly versatile in automotive, marine, outdoor and various other uses. - Epoxy Sealed Waterproof Housing: The buck converter is securely housed in an epoxy sealed enclosure, offering excellent waterproof properties for reliable performance in different environments. - Overload and Voltage Protection: The step-down converter is designed with overload, over-current, over and under-voltage protection, ensuring stable performance and longevity of the device. - Perfect for Automotive Applications: Excellent for converting from a car's 12V battery to 9V - Easy to Use: The inputs and outputs are labeled on the sticker on top of the converter, the red and black wires are the + and - 12V input, and the red and yellow wires are the + and - 9V output. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07QGXL9XP | | Best Sellers Rank | #297,834 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #1,353 in Power Converters | | Brand | Envistia | | Brand Name | Envistia | | Current Rating | 1.7 Amps | | Customer Reviews | 4.6 out of 5 stars 106 Reviews | | Item Dimensions D x W x H | 0.91"D x 1.06"W x 0.91"H | | Item Weight | 30 Grams | | Manufacturer | Chuangruifa | | Model | 9V 1.7A DC-DC Converter | | Mounting Type | Surface Mount | | Part Number | 9V 1.7A DC-DC Converter | | Power Source | Battery Powered | | Product Dimensions | 0.91"D x 1.06"W x 0.91"H | | Specification Met | CE, UL | | UPC | 732387204923 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Envistia - **Power Source:** Battery Powered - **Current Rating:** 1.7 Amps - **Item Weight:** 30 Grams - **UPC:** 732387204923 ## Images ![12V to 9V 1.7A Step-Down Waterproof Miniature DC-DC Converter Power Supply Module by Envistia Mall - Image 1](https://m.media-amazon.com/images/I/61NjO3dnZ0L.jpg) ![12V to 9V 1.7A Step-Down Waterproof Miniature DC-DC Converter Power Supply Module by Envistia Mall - Image 2](https://m.media-amazon.com/images/I/51Fdabds5sL.jpg) ![12V to 9V 1.7A Step-Down Waterproof Miniature DC-DC Converter Power Supply Module by Envistia Mall - Image 3](https://m.media-amazon.com/images/I/51Hnt0QzMPL.jpg) ![12V to 9V 1.7A Step-Down Waterproof Miniature DC-DC Converter Power Supply Module by Envistia Mall - Image 4](https://m.media-amazon.com/images/I/41BAJaLgaOL.jpg) ![12V to 9V 1.7A Step-Down Waterproof Miniature DC-DC Converter Power Supply Module by Envistia Mall - Image 5](https://m.media-amazon.com/images/I/61qvJxym-rL.jpg) ## Frequently Bought Together - 12V to 9V 1.7A Step-Down Waterproof Miniature DC-DC Converter Power Supply Module by Envistia Mall - Envistia Miniature 12V to 5V Step Down DC to DC Voltage Converter 3A 15W Waterproof Power Supply Module --- ## 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.sc/products/171736359-12v-to-9v-1-7a-step-down-waterproof-miniature-dc](https://www.desertcart.sc/products/171736359-12v-to-9v-1-7a-step-down-waterproof-miniature-dc) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-07-15*
