## Overview

The VooGenzek 2 PCS LED Voltmeter Ammeter features a dual-color 0.28" LED display that simultaneously shows voltage (0-100V DC) in red and current (0-10A) in blue. Designed for 12V/24V systems, it includes a built-in shunt for precise current measurement and reverse polarity protection to prevent damage. With a fast refresh rate and low power consumption, this modern panel meter offers reliable, real-time monitoring in a compact form factor.

## Description

Specifications: Voltage measurement range: DC 0V-100V Current test range: 0-10A Working voltage: 4.5-30 V DC (Note: if the voltage exceeds 30V, an external independent power supply is required) Voltage error: ±0.1% Current error: ±1% Working current: <20mA Refresh rate: ≥300mS / times Display: 0.28" Two color blue and red Operating temperature: -15℃ to 70℃ Working pressure: 80 to 106 kPa Package Included: 2 × LED Voltmeter Ammeter

Review: nice looking and useful - good thing: it works great. bad thing: it uses the negative rail.
Review: How to avoid current measurement error - The current measurement shunt is on the ground side. If you do use current measurement, then leave the small black negative wire on the voltage measurement connector floating. At first I mistakenly connected it to ground, and was getting a large current measurement error. When I let it float, the measurement was pretty accurate. The instructions in the pictures on the desertcart page say, "No need to connect". Ideally it would say, "Don't connect if measuring current".

## Features

- Voltage measuring range: 0-100 V DC; current measuring range: 0-10A (decimal point moves automatically).
- Display mode: Dual-colour digital display 0.28" LED digital tube Display color red+blue.
- Built-in Shunt: The 10A voltage and current meter itself has a built-in shunt.
- Color distinction: Led Display Voltage and current simultaneously in different colors, red for Voltage, Blue for current(the current is measured in the negative rail).
- Connection Protection: With reverse connection protection to avoid burning from reverse connection.

### ⭐⭐⭐⭐⭐ nice looking and useful
*by F***H on 23 April 2026*

good thing: it works great. bad thing: it uses the negative rail.

### ⭐⭐⭐⭐⭐ How to avoid current measurement error
*by K***3 on 20 June 2026*

The current measurement shunt is on the ground side. If you do use current measurement, then leave the small black negative wire on the voltage measurement connector floating. At first I mistakenly connected it to ground, and was getting a large current measurement error. When I let it float, the measurement was pretty accurate. The instructions in the pictures on the Amazon page say, "No need to connect". Ideally it would say, "Don't connect if measuring current".

### ⭐⭐⭐⭐ Worked well
*by D***H on 21 November 2023*

Used to monitor the output of two solar panels. Worked well. Not to confident the connector would last long at 10A, so soldered wires to the pins. Accuracy was a little off, but for indicators to give an idea of whats going on, they are accurate enough. No instructions with the item, so remember to print out the diagram in the listing for future reference.
