The voltage adjustability can be wonky but that is to be expected with the cheaper power supplies. But this is perfect for what I need it for: Testing electronics and building circuits. ### ⭐⭐⭐⭐⭐ Review *by G***0 on 20 May 2025* Excelente producto y calidad ### ⭐ Review *by C***N on 8 March 2025* Bought this to charge 12v trail cam batteries. Failed 2 mos after warranty. Would not set a amp setting. Contacted seller about possible repair, but they talked like they would honor the warranty. In the end they didn't, which I expected but then they told me this unit was not made for what I was using it for..WHAT! I told them if that is the case their add should reflect that. This unit charged them fine for awhile but then puked it up. You can come to your own conclusion but I ain't buying another one from NICE. ## Frequently Bought Together - NICE-POWER DC Power Supply Adjustable Variable 3-Digital LED Display Adjustable Regulated Switching DC Lab Bench Power Supply Digital (30V 10A Black) - Pure Zinc Anode Sheet 2pcs (99.995% Pure) for Plating, Zinc Electrode Strip 0.04''x1''x6'' - SHONAN 6 Inches Pure Nickel Sheets, 2 Pack Nickel Plates, Nickel Plating Kit for Electroplating, 99.6% Purity --- ## 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.at/products/475578897-nice-power-dc-power-supply-adjustable-variable-4-digital-led](https://www.desertcart.at/products/475578897-nice-power-dc-power-supply-adjustable-variable-4-digital-led) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-05-04*
