Feature:

This DC Voltage Meter with DC4.5-30V range. It is easy to read, install and use

And it is self-powered version and supports Reverse polarity protection.

When the voltage is under 10V, there will 2 readings after decimal point, which mean the accuracy is 0.01 when it is under 10V; when it is above 10v, the accuracy is 0.1

No power supply needed
