I use it with an old laptop power brick and use this as an adjustable power supply for my little projects. It works great for etching steel with salt water and a cotton swab. I use it to put my makers mark on knives that I make. I also use it for testing little electronics projects. It’s a bit fiddly to adjust because you need a tiny screw driver, but it works great. It’s been very reliable over the years I’ve had it. Review: DROK DC Buck Converter, 5.3V-32V to 1.2V-32V 12A Adjustable - Converting AC Led Strip to DC. Removed AC/DC 90v LED converter. Wired LED strips in parallel for 36v Amperage ran past 5 Amps. This was too much voltage and amperage for my Solar Carport Batteries at 11-14.5v. Purchased this Buck converter to regulate my voltage and current from the battery. Adjusted the Output to 12v. Then connected my DC-DC High Voltage Boost Converter 8V-32V to ±45V-390V and adjusted the output to near lowest output of 44.4v. Then adjusted the Dork Buck to 1.15 amps. Keeping a constant 12v 1a draw regardless of the Battery input from 10-15vdc at any high amperage. Works great on both of my carports and work shed. ## Features - 【Parameter】 DROK Power Supply Module input volt range is DC 5.3-32V; Output volt range is DC 1.2-32V which is variable.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great for etching steel. *by A***R on April 7, 2026* I love this little voltage converter.

Removed AC/DC 90v LED converter. Wired LED strips in parallel for 36v Amperage ran past 5 Amps. This was too much voltage and amperage for my Solar Carport Batteries at 11-14.5v.

Works great on both of my carports and work shed. ### ⭐⭐⭐⭐ Great unit with some items to be aware. *by A***R on March 11, 2025* Nice unit it provides a wide voltage range of output. Easy to set up an use. Nice touch with the adjustment buttons and plexiglass shields. What could use improvement, would be nice to have paper instruction or a link to instructions, the voltage display, it is a bit off when measured by 2 calibrated DVM's but it is in the right range. The other area for improvement is the ripple/switching noise is high at 500mv pk-pk for my application at 1.5vdc. Depending on your application this may be acceptable. I didn't check if this is consistent through the output voltage range. I plan on putting some type of filtering on the output to bring it down. Other items, great size, lots of functionality for the price point. ## 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.com.kw/products/56340225-drok-dc-buck-converter-5-3v-32v-to-1-2v](https://www.desertcart.com.kw/products/56340225-drok-dc-buck-converter-5-3v-32v-to-1-2v) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-18*
