The display shows only voltage and current associated with the main power outlets when output is enabled. When output is not enabled, the display shows voltage and max current settings. A USB connector could be connected to the main power output connectors and any voltage and current through that connector would be shown on the display. **Q: is this machine good for gold and silver plating?** A: I don't know what voltages are required for plating, but, it is a very good supply for the money. **Q: Can this be used as a short circuit killer to repair phones and circuit boards?** A: Yes, as long as it doesn’t exceed the max output rating 5A. It will go into protection mode beyond that point. I use mine daily and for the money it is top notch. **Q: Description says 100w, but at 10a x 30v, that should be 300w output. is the description wrong?** A: It means you can get 10 Amp at 10v ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very good *by K***P on 8 December 2025* Very compact, easy to use. ### ⭐⭐⭐⭐⭐ Good performance *by J***U on 18 October 2024* User friendly and nice,very good product. ## Frequently Bought Together - DC Power Supply Variable, Bench Power Supply with Encoder Adjustment Knob, Output Enable/Disable Button, Adjustable Power Supplies with USB Quick-Charge, Short Circuit Alam (30V 10A Black) - Sumnacon 4 in 1 Banana Plug Alligator Clip Pure Copper Fork Test Lead, 3.3 ft Multimeter Flexible Test Lead Wire Cable with Protective Jack Copper Clamps for Electrical Testing 1000V/15A - 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.be/products/439673243-dc-power-supply-variable-bench-power-supply-with-encoder-adjustment](https://www.desertcart.be/products/439673243-dc-power-supply-variable-bench-power-supply-with-encoder-adjustment) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-05-19*
