Also lost my manual. Can't find a link. Thanks..** A: I use mine for electroplating. When I hook it up, the amperage is adjustable and the voltage sets itself. I don't know why this is, but since I use milliamps and amps for plating, and I can adjust it, that is what I need. I suggest that you contact Tekpower customer service/technical department for further info. **Q: Can this be used to power a car amplifier in home ?** A: It depends on the amp draw of the amplifier. This piece of equipment, though, is meant for temporary bench testing and not for a continuous power supply. You would be better off looking for a power supply designed for continuous use. **Q: How many watts is this?** A: 18Vx3A = 54W **Q: so what is the smallest mA this device can deliver?** A: The lowest for me is 0.05 mA (50uA). For adjustments that depends a bit on the sensitivity of your finger. I needed to simulate a 4-20mA current sensor. I found that I could get better control by adjusting the voltage rather than the current. It was very easy to tune it in 0.2mA steps and I was kind of able to tune it in 0.01 mA steps but at this point it took me like 30 seconds to dial it and I was barely touching the nob. ## Frequently Bought Together - Tekpower TP1803D Lab Grade Variable Linear DC Power Supply, 0-18V @ 0-3A PC, with Alligator Cable and Power Cord,for Labs - Pure Graphite Powder Quart - ALDON Copper (II) Sulfate Solution, 1M, 500mL - The Curated Chemical Collection --- ## 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.pa/products/651678327-tp1803d-lab-grade-variable-linear-dc-power-supply-0-18v](https://www.desertcart.com.pa/products/651678327-tp1803d-lab-grade-variable-linear-dc-power-supply-0-18v) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-10-21*
