Package Include: 1* 250W DC-DC Boost Converter Constant Current Power Supply Module Review: excellent medium power boost converter - I originally bought one of these to keep a supercap box in my vehicle charged up to 14.5v volts, from the 12v supply of the truck, and it's working well. I configured the voltage to 14.5v and current to 5a, and mounted it inside the lid of the lid using stand-offs since it does get warm in use. The back of the board is a thin aluminum plate, which does a good job of heat dissipation, and the large coil does a good job of handling the rated power. I didn't need to add any additional heat dissipation though, the aluminum backing kept temps safe. (though do use standoffs to keep the board away from things like plastics) I ended up buying a second one as a spare since these are reliable and useful to have around when needing to boost voltage. (though you need at least 10 volts at the source) Adjusting the output voltage is easy, just turn the adjustment screw. Current is a little more tricky, you need to apply a load at the current you want, and then adjust the current limit screw to right before it starts cutting back the voltage. I've bought small boost converters and big ones, but this one fits right in the middle, where you have some voltage and need several (but less than 6) amps Review: Voltage can not increase - When I first time turned clockwise and counterclockwise the crew, voltage didn’t change. Second time I turned counterclockwise it worked. No manuals in package, better to have one. Otherwise people will complain and return it ## Features - Boost Step-up Constant Current Mobile Power Supply - Module properties: non-isolated step-up module (BOOST) - Input voltage: DC10V-40V - Output voltage: 10-50V continuously adjustable - Operating frequency: 150KHz ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07T137H2Y | | Best Sellers Rank | #21,591 in Electronics ( See Top 100 in Electronics ) #377 in International Power Adapters | | Brand | HiLetgo | | Brand Name | HiLetgo | | Customer Reviews | 4.0 out of 5 stars 217 Reviews | | Item Weight | 0.07 Kilograms | | Item weight | 0.07 Kilograms | | Manufacturer | HiLetgo | | Maximum Frequency | 150 KHz | | Model | 3-01-1209-A | | Mounting Type | Panel Mount or Flange Mount or PCB Mount | | Mounting type | Panel Mount or Flange Mount or PCB Mount | | Part Number | 3-01-1209-A | | Power Source | Battery Powered | | Power source | Battery Powered | | Specification Met | CE | | Specification met | CE | ## Product Details - **Brand:** HiLetgo - **Current Rating:** 6 A - **Mounting Type:** Surface Mount - **Power Source:** Dc Power Supply - **Product Dimensions:** 1.42"D x 2.76"W x 0.51"H ## Images ![250W DC-DC Module 10-40V to 10-50V 6A Adjustable Step-Up Power Supply Module 250W DC Booster Constant Voltage Constant Current Power Converter Module - Image 1](https://m.media-amazon.com/images/I/61S11l2ZtyL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ excellent medium power boost converter *by V***1 on 15 July 2025* I originally bought one of these to keep a supercap box in my vehicle charged up to 14.5v volts, from the 12v supply of the truck, and it's working well.

Second time I turned counterclockwise it worked. No manuals in package, better to have one. Otherwise people will complain and return it ### ⭐⭐⭐⭐⭐ Works great! *by D***. on 13 July 2022* I connected the boost converter (https://www.amazon.com/dp/B07T137H2Y) to an adjustable power supply module (https://www.amazon.com/dp/B01LWXAC5E) on the output. And I have a Volt/Ammeter (https://www.amazon.com/dp/B072BY4XZ7) on the input. All supplied by a 12V marine deep-cycle battery on the input. It was giving me 24v out from the start. I need 48v so I dialed this boot converter up to 50v, and fine-tune the output using the adjustable module. Been running for 2 weeks 24/7 and it's driving 7watts during the day and 15watts at night. No troubles so far! The output is powering a PoE ethernet hub that as a pair of PoE cameras (https://www.amazon.com/dp/B07V1WKRBB). It's all working really well! Once I'm done will the cameras, this will be my workbench power supply. ## Frequently Bought Together - HiLetgo 250W DC-DC Module 10-40V to 10-50V 6A Adjustable Step-Up Power Supply Module Constant Voltage Constant Current Power Converter - UCTRONICS Numerical Control DC 6-55V to 0-50V 5A Step Down Stabilized Power Supply Constant Voltage Current Buck Power Converter Power Supply Adjustable Module - Hilitchi 40 Pcs Binding Posts Terminals 4mm Banana Plug Socket (20pcs) + Red and Black Gold Plated 4mm Banana Plugs(20pcs) for Arduino --- ## 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.co.uk/products/369342764-250w-dc-dc-module-10-40v-to-10-50v-6a](https://www.desertcart.co.uk/products/369342764-250w-dc-dc-module-10-40v-to-10-50v-6a) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-08-29*
