Been working ok for12months so far. ### ⭐⭐⭐⭐⭐ nice looking and useful *by F***H on 23 April 2026* good thing: it works great. bad thing: it uses the negative rail. ### ⭐⭐⭐⭐ You need some electrical or electronics knowledge. *by C***L on 10 June 2024* There are no instructions beyond the Amazon page. Thin red and black wire are the meter power. 5V is best, as higher will make the on-board regulator hot. Then the yellow wire measures the voltage maybe up to 99.9V. The Voltage decimal point doesn't move for less than 1V or at all. The current meter is actually a 1V approximately max voltmeter for 50.0 A on display. Thus the shut drops 0.2V at 10A, which is 2W. I expect the shunt, which is a surface mount resistor gets a bit two hot at 10A. Being experienced at electonics I removed the shunt. Then suitable external resistor can be used, A 20 ohm shunt will thus measure 0 to 50 mA, with the decimal point shifting one to the left for less than 1.0 on the display (was 1A, now 1mA), thus 0.99 down to 0.01. I'd not use the built in shunt for more than 2.5A. The adjusters are to calibrate voltage and current. ## Frequently Bought Together - VooGenzek 2 PCS 0.28" LED Voltmeter Ammeter, Red and Blue Detector Voltage Current Meter Panel Amp Volt Gauge, DC 0-100V 10A for 12V / 24V Multimeter Amperage Meter Volt Amp Gauge Panel - Hailege 3pcs XL4015 5A DC to DC CC CV Lithium Battery Step Down Charging Board Led Power Converter Charger Step Down Module --- ## 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.pl/products/397621898-voogenzek-2-pcs-0-28-led-voltmeter-ammeter-red-blue](https://www.desertcart.pl/products/397621898-voogenzek-2-pcs-0-28-led-voltmeter-ammeter-red-blue) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-29*
