I have 4 of them that I used to moniter power supply outputs and they work great, ### ⭐⭐⭐⭐⭐ They work! *by C***N on August 23, 2025* I have used these on various projects and they work very well. A very good value. ### ⭐⭐⭐⭐ Poor documentation. Works well when all is corrected. *by T***K on January 5, 2022* I am an electrical engineer with extensive experience in digital electronics. I used two of these meters to replace defective analog meters in a power supply. I found the connection diagram easy to use but both meters in the 2-pack are showing incorrect voltage and current readings. After much searching for documentation I discovered that when connected to a power supply using that power supply to power the display that the thin black wire must be left unconnected. With that fix the two calibration adjustments worked. ## Frequently Bought Together - HiLetgo 2pcs 0.28" Digital Voltmeter Ammeter DC 100V 10A Amp Voltage Current Meter Tester 0.28 Inch 3 Bits Blue + Red Dual LED Display Panel with Connect Wires - BIQU 15A 250V Rocker Switch Power Socket Inlet Module Plug 5A Fuse Switch with 5Pcs 16-14 AWG Wiring 3 Pin IEC320 C14 - Taiss 2pcs 3590S Rotary Potentiometer 10k ohm Potentiometer 10-Turn Wire Wound Precision, Precision Multi Turn Wirewound Potentiometer+2pcs A03 knob (3590S-2-103L 10k ohm) --- ## 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.it/products/102820772-hiletgo-2pcs-0-28-digital-voltmeter-ammeter-dc-100v-10a](https://www.desertcart.it/products/102820772-hiletgo-2pcs-0-28-digital-voltmeter-ammeter-dc-100v-10a) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-10*
