Small size so you do not need large space. Easy to use it. Like it. ### ⭐⭐⭐⭐⭐ Works, numbers light up niceu *by A***S on February 11, 2024* Purchased this to anodize aluminum in the .58 square foot size using the low current density method. Also successfully used it for etching aluminum. Works well for constant current. Numbers were easy to read, and no overheating problems with 2 hour runs. I didn’t test it for accuracy against a multi-meter. It has no hum. Nice small profile. ## Frequently Bought Together - Naweisz DC Power Supply Variable 30V 5A Precision Adjustable with 4-Digital LED Display - Alligator Leads for Lab Equipment, DIY Tool, Repair, Electronic Research - MAIYUM 63-37 Tin Lead Rosin Core Solder Wire for Electrical Soldering (0.8mm 100g) - Weller 70 Watt Digital Soldering Station | WE1010NA --- ## 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.ie/products/95942838-30v-5a-dc-bench-power-supply-variable-3-digital-led](https://www.desertcart.ie/products/95942838-30v-5a-dc-bench-power-supply-variable-3-digital-led) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-06-11*
