Also switched it to AC volts and got 3 mV, so not an excessive amount of ripple. For the price it seems to be a fantastic deal. Review: Great power supply - My old power supply died so I found this one and it works great for anodizing titanium which is all I need it for. It’s easy to set up and use and everything is straightforward. ## Features - 1️⃣【4-Digit Display & Power Calculation】: The Jesverty SPS series features a big bright 4-digit LED display that shows measured values of V／A／W that the unit outputs in real-time.

Also switched it to AC volts and got 3 mV, so not an excessive amount of ripple. For the price it seems to be a fantastic deal. ### ⭐⭐⭐⭐⭐ Great power supply *by R***R on April 13, 2026* My old power supply died so I found this one and it works great for anodizing titanium which is all I need it for. It’s easy to set up and use and everything is straightforward. ### ⭐⭐⭐⭐⭐ Good shopping experience *by J***N on June 10, 2025* I was delayed in continuing my electronics project, when I did resume I found that there was a fault in this new unit, which had passed beyond its return deadline. Even so the seller promptly upon understanding the issue sent a replacement power supply. This service was excellent, sometimes things get by and don't work & that's when you learn whether you are dealing with a reputable seller who is self-responsible, or not. This seller is excellent and stands 100% behind their product. This is significant today where you can buy a component or device and have no idea about who the manufacturer is or even if the product is real. Jesverty is a good manufacturer as indicated by the many positive reviews they receive - including this one! ## Frequently Bought Together - Jesverty DC Power Supply Variable, 0-120V 0-3A Adjustable Switching DC Regulated Bench Power Supply with High Precision 4-Digit LED Display, 5V/2A USB Port, Coarse and Fine Adjustment SPS-12003 - Sumnacon Multimeter Banana Plug to Crocodile Alligator Clip Test Probe, 5PCS 4mm Stackable Colorful Silicone Banana Plug to Alligator Clip Test Probe Lead Wire Cable 1M - 2Pcs 4mm Banana Plug to Alligator Clip Test Lead Wire Cable Set 14AWG for Multimeter Oscilloscope 3 Feet --- ## 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/469664339-dc-power-supply-variable-0-120v-0-3a-adjustable-switching](https://www.desertcart.co.uk/products/469664339-dc-power-supply-variable-0-120v-0-3a-adjustable-switching) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-26*
