Review: Nice little panel meters - Good looking blue LED display with a very small footprint. Good accuracy from 0 to 30V running off of a 5V supply. These do not measure negative voltages.
Review: Got what I paid for - They work accurately enough to give you a point of reference. Not expensive, so not top tier. Example: Vehicle is charging at 14.4v@idle as verified on multimeter at display connection, adjust pot to calibrate this display to match meter, then turn off car to see 12.4 on meter and 12.7 on this display.... As stated, ideally used as a point of reference (you are above or below your target range). The deviation will spread as the range gets wider, but it's perfect for a voltmeter in the dash or on an amp. Just a monitoring tool, not a diagnostic tool.

## Features

- This is Three-Wire Voltmeter. Three-Wire connection enable the Voltage Test Rang from 0.00 to 30V. (Two-wire meters cannot measure the voltage that is below 3V);
- Measurement Accuracy: 0.01(0.01 - 9.99V) / 0.1(10.0 - 30.0V); And the meter is CALIBRATABLE: The screw on the back is used to Calibrate the meter.
- BRIGHT & NICE Reading: Display: Three 0.36" digital LED Tube; Display Color: BLUE;
- Reverse Polarity Protection: The meter won't burn out if reverse polarity is applied, but the screen will display nothing
- NOTE: When measured voltage is larger than 30V, the voltmeter will be damaged.

### ⭐⭐⭐⭐⭐ Nice little panel meters
*by J***. on December 11, 2025*

Good looking blue LED display with a very small footprint. Good accuracy from 0 to 30V running off of a 5V supply. These do not measure negative voltages.

### ⭐⭐⭐⭐⭐ These work great and are very bright.
*by L***S on November 11, 2022*

These are great little devices. I build various size battery packs and use these to determine their state of charge. The wide voltage range of 0-30v is perfect for my application They are very easy to use. If you don't need to measure < 3v than the simple two wire connection is all you need. It doesn't get much easier than that. Even in daylight the blue display is bright and easy to read. All 5 of the voltmeters I received measure accurately and identical. Good quality. Highly recommend.
