Output current can reach to 8A and Output Power can reach to 120W for long-time use. If enhance heat dissipation, this converter can reach 12A and 160W output. - 【Characteristics】 This Buck Converter is equipped with LCD Display, Acrylic Case and Heat Sink. LCD Screen can display input/output voltage, output current and output power. Voltage precision is 0.05V, current precision is 0.005A. Acrylic case can keep the converter board away from dust, which is protective. Heat Sink can keep module 120W for long-time using in a low temperature. If you want to reach maximum power 160W, please improve heat dissipation. - 【Easy Operation】 A user manual will be included in package, which can help you easier to operate. The button can control ouput voltage ON/OFF status, and you can set the default output state is ON/OFF for the next time. The potentiometer can help you to adjust volt amp in a simple and fast way. - 【Protection】 It has reverse-connect protection, short circuit protection and over current protection. When you connect the input wire reversely or short circuit, the module will not burn. And roate the CC potentiometer to set over current protection value you want. - 【Application】 The volt conversion board can be used for 5v 6v 9v 12v 24V 30V 32V 3a 5a 10a devices, like solar panel, lab, experiment, RV, All-Terrain Vehicle, car, battery charger, LED stripes, etc. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B078Q1624B | | Best Sellers Rank | #21,712 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #84 in Power Converters | | Brand | DROK | | Color | blue-1 | | Customer Reviews | 4.3 out of 5 stars 1,049 Reviews | | Input Voltage | 32 Volts | | Item Dimensions | 1.97 x 1.97 x 1.97 inches | | Item Weight | 90 Grams | | Item dimensions L x W x H | 1.97 x 1.97 x 1.97 inches | | Manufacturer | DROK | | Mfr Part Number | REES-1822 | | Model Number | REES-1822 | | Number of Outlets | 1 | | Output Voltage | 32 Volts | | Power Source | Battery Powered | | UPC | 678535742056 | ## Product Details - **Brand:** DROK - **Color:** blue-1 - **Input Voltage:** 32 Volts - **Item Weight:** 90 Grams - **Item dimensions L x W x H:** 1.97 x 1.97 x 1.97 inches ## Images ![DROK DC Buck Converter, 5.3V-32V to 1.2V-32V 12A Adjustable Power Supply, 5v 9v 12v 24V 30V 32V Step Down Voltage Regulator with LCD Display Volt Transformer Reducer CC CV for RV Solar Panel Golf Cart - Image 1](https://m.media-amazon.com/images/I/71zz5BaeTbL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: How would i use this as a constant voltage supply if i don’t want a constant current supply (eg, i don’t want to accidentally spike the output v) ?** A: For me this has been a marvelously useful device. I power it with the charger "brick" from a retired laptop PC, capable of as much as a couple amps at 25VDC. The specifications don't make it clear, but you independently set the maximum output current and output voltage using the on-board 10-turn pots while monitoring it on the display. For example when charging a lithium-ion battery, its specs might suggest a the maximum charging current of 0.5A and maximum output voltage of 4.2V. So first, you set the open-circuit voltage to 4.2V. Turn the output current to minimum and connect the batery. Assuming the battery is pretty well discharged, when you first connect it you could potentially sink as much as several amps but that would hurt the battery. No problem, you've set the current to minimum (a few mA). When you connect the battery, turn up the current to 0.5A; the voltage will rise as you turn up the current, probably settling around 3.5V. (I am assuming that your power source will easily supply the required power.) As the battery charges, the voltage will gradually increase to 4.2V while the current stays at 0.5A. But once the voltage gets close to 4.2V the current will start to taper off. If left for several hours the voltage will still be at 4.2V but the current will be only a few mA. So the supply acts like constant current, then transitions to constant voltage. I hope this answers your question. I haven't seen any evidence of loss of control over either output voltage or current. FYI it's worthwhile to experiment with the unit connected to an output load resistor first, to get an understanding of which buttons to press to read the desired values. From memory, you can read input voltage and current, temperature of the heat sink in F or C, and output voltage and current. And you can also read output voltage independent of supplying power to the load (i.e. it can act like a voltmeter). **Q: What does opp error mean?** A: Dear customer, OPP:Over-power Protection When output power reaches 35W, OPP will be enable. Best regards. **Q: Is there an operating/owners manual** A: Good day. You can get the user manual on product detailed page ---> Product information ---> Technical Specification ---> User Manual [pdf ] You can also get it via the link below: https://images-na.ssl-images-amazon.com/images/I/C1RCvx6bFMS.pdf If there are any problems, please feel free to contact through Amazon's direct messaging service: https://www.amazon.com/ss/help/contact/?_encoding=UTF8&marketplaceID=ATVPDKIKX0DER&ref_=v_sp_contact_seller&sellerID=AFHAE9RJVUMB Best regards. **Q: I need to increase voltage from 11V to 15V, can it do it?** A: Yes this will work. This morning I needed to run 2 12V PC fans from a USB 2.0 port. It worked drawing around 400mA. ## Frequently Bought Together - DROK DC Buck Converter, 5.3V-32V to 1.2V-32V 12A Adjustable Power Supply, 5v 9v 12v 24V 30V 32V Step Down Voltage Regulator with LCD Display Volt Transformer Reducer CC CV for RV Solar Panel Golf Cart - APIELE 16mm Latching Push Button Switch 12V DC On Off Black Shell with LED Angel Eye Head for 0.63" Mounting Hole with Wire Socket Plug Self-Locking (Blue/Black Shell) - ARRAROWN ZK-1002T 2.0 Channel Bluetooth 5.0 Amplifier Board 200W HiFi Subwoofer Audio AMP with Treble and Bass Control BT and AUX Inputs, DC 12-24V 2.0 Channel Stereo AMP Module for DIY Speakers --- ## 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.be/products/56340225-drok-dc-buck-converter-5-3v-32v-to-1-2v](https://www.desertcart.be/products/56340225-drok-dc-buck-converter-5-3v-32v-to-1-2v) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-07-21*
