Review: Work great. Accurate enough. I will be buying more to save my tools. - Great for B&D 20v converted tools with the "power wheels adapter". B&D Batteries or tools dont have a low voltage shutoff circuit. Relies on the motor requiring 15v. So if you use those batteries in other tools with adapters. You can drain them to a point of no recharge. This lets you monitor the voltage on tools to ensure you never drop past 16.5 volts. You are the low voltage shutoff circuit :D
Review: Fun, cheap, accurate, useful - Keeps working down to about 3 volts, which is impressive. I compared measurements with my expensive multimeter and these little displays are satisfyingly accurate.

## 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: Red;
- 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.

### ⭐⭐⭐⭐⭐ Easy to use and accurate little voltmeter.
*by T***R on May 19, 2020*

Great little voltmeter! Mounting is easy, I 3D printed a shroud to help with this and added some smoky Lexan to cut the brightness down a bit and improve the contrast. Calibration is simple and accurate, I set the 10ths digit to roll over to the next value with the input voltage reaches 0.05V (i.e. an input voltage of 12.44 reads as 12.4 on the LED, and 12.45 reads as 12.5). The accuracy is very good over the input range and the 10ths digit does not jump around excessively. Overall this is a very easy to use and acceptable voltmeter for most projects. I used it here in a mobile amateur radio setup to measure power supply/battery voltage and boosted voltage. I do wish the 3 wires were accessible so you could join the white and red (voltage for the LCD driver and voltage to measure) but they solder to the surface of the PCB under the LED, not a big deal though.
